The human auditory system is usually divided into 3 parts-- the inner, middle and outer ear. The middle ear starts at the eardrum and comprises also the ossicles, which are connected to the oval window of the cochlea. Another function of the eardrum is to separate air in the auditory canal from that in the middle ear, which is connected to the larynx via the eustachian tube. It's worth spending some time examining the function of the cochlea, which is depicted schematically below.
The cochlea is ultimately responsible for converting sounds to electrical signals that encode both the frequency content and spectral amplitude. The cochlea is a somewhat spiral-shaped organ comprising two fluid-filled regions, the scala vestibuli and the scala timpani. The shape of the scala media, bounded on one side the Reissner's membrane and the other by the tectorial membrane is specialized such that the tectorial membrane vibrates maximally at locations determined by the frequency content of the sound signal.
The concept of a correlation between fluid pressure wave maxima and the frequency content of a sound signal is called the Place Theory of Hearing. The critical band describes the zones of the basilar membrane that respond maximally to particular frequencies of pure tones.
We can first test what happens as two identical frequencies are separated by slowly changing the frequency (pitch) of one of the function generators. The textbook speaks of a 'courseness of tone' just when the beats get fast and just before we can distinguish two tones.
We can also set up one function generator to frequency modulate the other about some central frequency. Earlier we mentioned a neural processing technique called sharpening that allows us to hear very small changes in frequency. As mentioned earlier, the amplitude response (dynamic range) of the human ear is very broad. Technically speaking, sound intensity levels are expressed in Bels (named after Alexander Graham Bell), and a decibel is one tenth of a Bel. Further, a 30 dB decrease in sound intensity is a reduction by a factor of 1,000 (divide original intensity by 1,000). The decibel scale of SIL corresponds to what we hear, in that a 10dB increase in SIL is heard as the same change in loudness, irrespective of the starting sound level. There are other tidbits in the textbook, including an interesting discussion of fundamental tracking.
The reduced pressure between the vocal folds causes them to pull together and nearly close, causing air pressure to build up in the trachea below the folds. The lips are generally used to set the frequencies of the lowest formants, while the tongue, soft palate and other parts are used to shape the 'vocal tube' to emphasize or deemphasize higher frequency formants. It would be helpful to see some wave shapes, Fourier spectra and spectragraphs for various formants, best simulated by singing single note vowel sounds such as 'oo,' 'ah,' and 'ee'.
If there is a 'guest soprano' in class on Tuesday, we can record and examine what happens when that individual sings high notes. The temporomandibular joint (TMJ) is the area right in front of the ear on either side of the head where the upper jaw (maxilla) and lower jaw (mandible) meet. The temporomandibular joints are very complex and are made up of muscles, tendons, a disc and bones.You have a temperomandibular joint on each side of your jaw (right and left side).
Micro trauma is considered internal, such as grinding the teeth (bruxism) and clenching (jaw tightening). TMJ pain can usually occur because of unbalanced activity, spasm, or overuse of the jaw muscles. Most patients are quite successful with conventional conservative therapy (such as resting the jaw or night guard). We are a full service dental practice that specializes in relaxation and cosmetic dentistry services, dental implants, TMJ disorder treatment, periodontal disease treatment, teeth whitening, porcelain crowns and porcelain veneers, and other restorative dental care.
A cholesteatoma is a skin growth that occurs in an abnormal location, the middle ear behind the eardrum. Cholesteatoma is a serious but treatable ear condition which can only be diagnosed by medical examination. Otitis media is the inflammation of the middle ear and occurs most commonly during the winter and early spring months.
Remember, without proper treatment, damage from an ear infection can cause chronic or permanent hearing loss. Earwax is healthy in normal amounts and serves to coat the skin of the ear canal where it acts as a temporary water repellent.
Most of the time the ear canals are self-cleaning; that is, there is a slow and orderly migration of ear canal skin from the eardrum to the ear opening. When cerumen is removed from the ear, the physician uses sucion, a cerumen spoon, or delicate forceps to do so.
A perforated eardrum is a hole or rupture in the eardrum, a thin membrane that separates the ear canal and the middle ear.
Middle ear infections may cause pain, hearing loss, and spontaneous rupture (tear) of the ear-drum resulting in a perforation. On rare occasions a small hole may remain in the eardrum after a previously placed PE tube (pressure equalizing) either falls out or is removed by the physician.
Most eardrum perforations heal spontaneously within weeks after rupture, although some may take up to several months.
The most common symptoms of swimmer’s ear are mild to moderate pain that is aggravated by tugging on the auricle and an itchy ear. WARNING: If you already have an ear infection, or if you have ever had a perforated or otherwise injured eardrum, or ear surgery, you should consult an ear, nose, and throat specialist before you go swimming and before you use any type of ear drops.
The tympanogram is a test that measures how easily the eardrum vibrates back and forth and and what pressure the vibration is the easiest. The ABR is a special hearing test that can be used to track the nerve signals arising in the inner ear as they travel through the hearing nerve (called the auditory nerve) to the region of the brain responsible for hearing.
The ABR can also be used on small infants since it requires no conscious response from the person being tested.
The ENG (short for electronystagmogram) is actually not a hearing test but rather a special test of the balance mechanism of the inner ear.
There are several parts of the ear, which are divided into the outer, middle and inner ear sections. The different parts of the ear allow the body to capture sound waves out of the air, translate them into vibrations and send these signals to the brain to be interpreted. The outer ear is the portion of the ear that sits atop the skull, which is made of flesh and cartilage. The middle ear contains tissue and bone but no skin, and is the area where sound is translated into mechanical energy so it can pass through the body. The eardrum, known scientifically as the tympanic membrane Is a thin piece of tissue that is stretched between the outer and middle ear. The anvil bone or the incus sits on top of the hammer, and will collect the vibrations coming from the ear drum, sending them on to the stirrup. The stirrup or stapes sits below the anvil, and is the final bone in the inner ear to collect and pass on sound.
The inner ear is the portion of the ear which is responsible for translating the message and sending it to the brain where it can be interpreted.
These nerves receive the electrical impulses generated by the ear and pass this information up to the brain so it can be interpreted. These are attached to the cochlea, but do not spend much time interacting with the hearing portion of ear function. What causes hearing loss?Losing your hearing is a normal and inevitable part of the ageing process.
Action on Hearing Loss: Enjoy the sparks but avoid the ringing in your ears this bonfire night. Michael Rothschild, MD, director, pediatric otolaryngology, Mount Sinai Medical Center, New York. National Institute on Deafness and Other Communication Disorders, National Institutes of Health. To provide even greater transparency and choice, we are working on a number of other cookie-related enhancements.
From time to time, you may have hear this…”ringing sound”, that hovering around your eardrum. I believe that you would agree with me that living with ringing sounds is definitely not a pleasant experience. In this post, I would like to share some remedies which work pretty well in eliminating my tinnitus. You should NEVER left your ringing ears untreated as it could possibly lead to more health issue.
This can be compared to the human eye, which can detect light frequencies (colors) that vary by less than a factor of 2. As mentioned before, the eardrum and the ossicles provide preamplification of sound signals. Holes in the eardrum allow unwanted, rapid equilibration between canal and middle ear pressures, which ultimately reduces the preamplication of sounds, particularly for lower frequencies.
It even detects phase differences between signals from the same source detected at each ear for purposes of location. Sounds signals transmitted by the ossicles to the oval window set up pressure waves within fluids in the scala vestibuli which travel down a narrowing chamber (the scala vestibuli) and continue along the scala tympani.
These localized vibrations cause shearing of the stereocillia (or hair cells) which, in turn, excite electrical impulses in the organ of corti which ultimately drive signals along the auditory nerve.
An experimental observation that two pure tones separated by an octave (a factor of 2 in frequency) excite equally-spaced regions along the sensor-studded basilar membrane. What do we hear when, instead, if we start with identical frequencies and slowly move them apart?
This is useful for observing the minimal frequency variation where we can hear a difference in tones-- called the Just Noticeable Difference (or JND).
This process evidently uses the higher frequency content (think overtones) of signals to improve (fundamental) frequency resolution. The ear can sense variations in pressure of 1 part in 10,000,000,000 (10^10th) of atmospheric pressure.
The decibel is set up so that every increase in sound intensity level by a factor of ten corresponds to a 10dB increase. In other words, we would interpret an increase of SIL from 10 to 20 dB as an equivalent change in loudness to that from 80 to 90 dB. This phenomenon is observed when we hear two successive overtones (but not the fundamental) of an overtone series. Air moving faster through constrictions in the vocal folds (gaps between them, etc.) creates a reduced pressure via the Bernoulli principle.
The speaker or singer controls the frequency of the source sound by tensioning the vocal flaps, and controls amplitude by varying the average air pressure available just below the vocal folds. The latter causes serves to shorten the length of the resonant cavity-- opening ones mouth widely moves the position of the pressure node to just inside the mouth for example. Guitar players, think of how you change where you pick in order to emphasize higher overtones or not. Muscles attached to and surrounding the jaw joint control the position and movement of the jaw. Patients may complain that it is difficult to find a  comfortable bite or that the way their teeth fit together has changed.  Chewing on only one side of the jaw can lead to or be a result of TMJ  problems.
This continuous pounding on the temporomandibular joint can change the alignment of the teeth.


This trauma can fracture the jawbone, cause dislocation of the TMJ, or cause damage to the cartilage disc of the joint. It is very common for people under stress to release this nervous energy by either consciously or unconsciously grinding  and clenching their teeth. About 80% of patients with a TMJ disorder complain of headache and about 40% report facial pain, and ear pain.
About one half of patients with a TMJ disorder notice ear pain and do not have any signs of ear infection. Grinding, crunching, clicking, or popping sounds (medical term = crepitus) are common for patients with a TMJ disorder. If your symptoms persist, your doctor may recommend medications or a night guard to help keep you from grinding your teeth at night. Dentist or doctor will recommend over the counter medications (like Aleve or Motrin), or prescription medications such as Dolobid are a first option to relieve pain. Antidepressants prescribed to be taken at bedtime have been successful in relieving TMJ pain in some patients. These types of drugs are sometimes used for a few days or weeks to help relieve pain caused by TMJ disorders.
Injecting botulinum toxin (example Botox) into the jaw muscles may give relief to pain associated with TMJ disorders.
For patients who grind their teeth patients may gain from wearing a  firm custom made appliance. For patients whose main symptom is from stress or anxiety they may benefit from a visit to a psychotherapist.
The success of treatment depends on how severe the symptoms are and how well you comply with treatment.
Marielaina Perrone's advanced training and years of experience translate into greater confidence and convenience for your entire family. These funnel through the ear opening, down the ear, canal, and strike your eardrum, causing it to vibrate.
It is usually due to repeated infection, which causes an ingrowth of the skin of the eardrum.
Persisting earache, ear drainage, ear pressure, hearing loss, dizziness, or facial muscle weakness signals the need for evaluation by an otolaryngologist-head and neck surgeon.
Old earwax is constantly being transported from the ear canal to the ear opening where it usually dries, flakes, and falls out. However, if you want to clean your ears, you can wash the external ear with a cloth over a finger, but do not insert anything into the ear canal.
It typically occurs in swimmers, but the since the cause of the infection is water trapped in the ear canal, bathing or showering may also cause this common infection.
If you do not know if you have or ever had a perforated, punctured, ruptured, or otherwise injured eardrum, ask your ear doctor. This graph shows the amount of hearing loss expressed in units called decibels at different sound frequencies (also called Hertz). The middle ear is normally filled with air at a pressure equal to the surrounding atmosphere. A special probe is placed up against the ear canal, like an ear plug, and the equipment automatically makes the measurements. The test is useful because it can tell us where along that path the hearing loss has occurred. The test involves running a cool liquid and then a warm liquid through the ear canal (it is usually done through a small tube so the ear itself remains dry).
If any portion of this system is harmed, it can be difficult to hear, or the patient can lose hearing in that ear all together. This organ is a key portion of the auditory system, which translates sound waves into a signal that the brain can interpret.
This is the physical portion of the ear that you see on the side of your head, which is used like a satellite dish to collect sound and transmit it inward where it can be translated into the appropriate medium. This 2 cm canal helps to amplify sound as it enters the middle ear so it can be interpreted properly. Most diseases such as ear infections will take hold in the middle ear, though some can also affect the inner ear.
It is called the drum because sound waves will hit it and cause it to vibrate, which will take the sound from acting as wave energy and translate it to mechanical energy that can travel through the rest of the ear. It is connected to the ear drum, and will vibrate as the drum is hit by the sound waves, passing the sound on to the rest of the ear.
These sound waves will cause the stirrup to compress, compressing the waves so they can be passed on to the inner ear.
It is filled with fluid that helps to balance the ear organs and comprise the hearing so it can be passed to the nerves.
Instead, these fluid filled tubes will turn and sway with movement, helping you keep your balance. Pressure in ear may be caused by various factors and is often accompanied by other symptoms.
Action on Hearing Loss (formerly RNID) says more than 70% of people over the age of 70 have some degree of hearing loss. It is intended for general information purposes only and does not address individual circumstances.
Together, I want to further improve our health status and continue to enjoy good health as we age. The dynamic range-- the difference between the quietest and loudest sounds we can hear-- is about 130dB (decibels, we'll get to these in a while) which corresponds to a factor of 10^12th (that's 10,000,000,000,000).
The eardrum is also equipped with a specialized muscle-- the tensor tympani muscle-- which can help dampen loud sounds and protect the inner ear. The cochlea is where pressure waves in fluids, excited by movement of the stirrup bone against the oval window, are converted into electrical impulses that travel up the auditory nerve to the brain. The round window at the far end of the combined chambers is set up to minimize reflections of pressure waves which would travel backwards. The stereocillia and organ of corti rest upon the basilar membrane which is about 3.5 cm long and contains about 30,000 nerve endings (hair cells). It also corresponds to about 15 percent in frequency, slightly less than a minor third in musical terms. We can experiment by discerning what our frequency resolution is for square waves as opposed to sine waves (the latter have minimal overtone content when produced by our function generator).
Loud sounds cause pain (the effective upper limit) at about 1 part in 10,000 (10^4th) of atmospheric pressure. Because the dynamic range of human hearing is very large (factor of 1,000,000), and because the frequency response of the ear is non-linear (the same ratio between two frequency stimuli is always perceived to be the same musical interval), we use the logarithmic decibel (dB) to express sound intensity level (SIL). You will often see loudspeaker specifications indicating the frequencies where sound intensity is halved, or decreased by 3dB. The neural mechanism of the ear recognizes the two overtones as part of a harmonic series and will be heard as the fundamental. Those sound waves are filtered by changing the shape of the vocal tract comprising the larynx, the pharynx above it, the mouth and the nasal cavity. An analogy is a perfume atomizer, where air is blown across a small opening above a bottle of perfume and the low pressure at the orifice draws out very small beads of perfume into the air stream. Thus, the vocal folds are regularly closing and opening, creating sound by varying pressure in the larynx above.
The resonant frequencies of this chamber are controlled by altering the shape of these cavities and, thus, serve to filter the sounds produced. When the muscles are relaxed and in balance and both jaw joints open and close comfortably, we are able to talk, chew, or yawn without discomfort or pain.
A problem with either one can lead to stiffness, headaches, ear pain, bite problems ( also called a malocclusion), clicking sounds, or locked jaws. Teeth grinding as a habit can result in muscle spasm and inflammatory reactions, thus causing the initial pain. Pain in the TMJ can also occur following dental treatment whereby the joint is stretched open for extended periods of time. 50% of those patients will have resolution of their tinnitus after successful treatment of their TMJ disorder. Your dentist will conduct a careful patient history, dental examination, and take necessary x-rays to determine the cause of your symptoms. This night guard prevents your teeth from coming together in contact, and repositions teeth to decompress the jaw joint. This would allow the patient to become self aware of stress triggers as well learning relaxation techniques to relieve stress.
As always, it is best to maintain regular appointments to see your dentist and let them know if there any TMJ issues developing.
You’ll find complete dental expertise, utilizing the latest advancements in dentistry, all here under one roof. The vibrations are passed to the small bones of the middle ear, which transmit them to the hearing nerve in the inner ear.
Cholesteatomas often take the form of a cyst or pouch that sheds layers of old skin that builds up inside the ear. The middle ear is connected to the nose by the eustachian tube, which equalizes pressure in the middle ear.
When water is trapped in the ear canal, bacteria that normally inhabit the skin and ear canal multiply, causing infection and irritation of the ear canal.
Simple tests, such as ones done in many schools, may be useful for screening, but a careful audiogram is necessary for accurate diagnosis of most hearing problems.
If the middle ear is filled with fluid, the eardrum will not vibrate properly and the tympanogram will be flat. For example, the ABR is often used for individuals with a sensorineural (nerve) loss in just one ear. Special electrodes automatically record the nerve signal; the patient can even be asleep during the test.
This change in temperature stimulates the inner ear which in turn causes rapid reflex movements of the eyes.
Understanding the inner workings of your ear can help you understand what you need to do to encourage optimum ear health and safety.
In addition to helping the body take in auditory messages, the ear helps to maintain a proper head position. This area also contains cells which produce ear wax, which helps keep debris out of the middle ear. Although there are some simple home remedies to relieve ear pressure, complications may arise if it is not treated properly. However, while many of us will experience gradual loss of hearing over the years, noise exposure at home, work or leisure can also cause impairment. It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. As this is rather a common aliment that had been affecting 45% of population, you will find many remedies in market to address this irritating aliment.
Or did your doctor changes any prescribe drugs for you recently.Try to recall when did your ears start ringing?
However, excessive accumulation of earwax could lead to “blockage” of sound to be correctly perceive by our hearing sensation. This mechanism isn't foolproof, there is a time lag between when loud sounds are sensed and when the muscle is completely activated.
Sound pressure waves within the scala vestibuli are propagated through the Reissner's membrane into the scala media, which contains a fluid with different properties than those in the other scala.


The neural mechanism has evolved to receive this broad range of pitch and narrow it down to a more precise frequency range-- a process called sharpening. The rate at which the folds open and closed is controlled by tension which is controlled by muscles.
Thinking about the boundary conditions of this chamber, we note that the bottom of the larynx, just above the vocal folds is a pressure antinode. The principal vocal formants are at these frequencies, but can be manipulated simply by manipulating the tube diameter at the position of nodes and antinodes for various overtones.
The temporomandibular joint functions to move the jaw, especially in biting and chewing, talking, and yawning. We can also feel the joint motion if we put a little finger against the inside front part of the ear canal. Changes in the normal stimuli or height of the teeth, misalignment of the teeth, and changes in the chewing muscles may cause temporomandibular joint changes. Teeth grinding and clenching are habits that may be diagnosed in people who complain of pain in the temporomandibular joint or have facial pain that includes the muscles involved in chewing.
Massage and heat application following your dental appointment can help relive the discomfort.
These symptoms are usually caused by Eustachian-tube dysfunction (structure responsible for the regulation of pressure in the middle ear). Conventional treatment consists of a diet of soft foods along with warm compresses to settle down the tension of the muscles. Here, the vibrations become nerve impulses and go directly to the brain, which interprets the impulses as sound (music, voice, a car horn, etc.). Over time, the cholesteatoma can increase in size and destroy the surrounding delicate bones of the middle ear. If the middle ear is filled with air but at a higher or lower pressure than the surrounding atmosphere, the tympanogram will be shifted in its position. This movements are recorded, and from these we can get information about how well this balance mechanism is functioning.
The fluid in the ear also helps the body maintain a sense of balance so the body can maintain proper posture and coordination. As the nerves begin to vibrate they will turn these frequencies into an electrical pulse which will be sent up to the brain.
It's estimated that 10 million people in the UK – that's one in six - have some level of hearing loss. Never ignore professional medical advice in seeking treatment because of something you have read on the BootsWebMD Site.
It’s just that in day time, external noise masks off that sound from your hearing sensation. Start taking ginkgo biloba tablets (which is easily available in  most  pharmacy stores) and  you should “see” the positive result in a couple of weeks. Thus any minor increase in  blood pressure can easily aggravate any ringing sounds which presents in your eardrums.
Another page at (hyperphysics, Georgia State University {I presume this is what gsu stands for}) is also informative. The pinna collects more sound that would normally be available at the opening of the auditory canal, thus providing a modicum of preamplification. Dynamic range also varies according to frequency, with greater sensitivity between about 1000 and 6000 Hertz (approximately, this varies by individual). Instead of producing the fundamental with a very large pipe, the overtones for that fundamental frequency are played at the right proportions (using a smaller pipe) to trick the ear into hearing the fundamental (low) frequency.
Some men can produce a falsetto voice-- producing nearly sinusoidal sound by highly tensioning the vocal folds. The other end, at the opening of the mouth, is a pressure node like the end of an open tube. If a patient is experiencing TMJ difficulty the simple act of opening and closing your mouth can cause considerable pain. Opening your mouth allows the rounded ends of the lower jaw (condyles) to glide along the joint socket of the temporal bone. These can include arthritis, trauma to the jaw, or muscle fatigue from clenching or grinding your teeth. Ear specialists are routinely called on to make the definitive diagnosis of a TMJ disorder.
It is believed that patients with TMJ syndromes have hyperactivity (muscle spasms) of the muscles responsible for regulating the opening and closing of the Eustachian tube. Hearing loss, dizziness, and facial muscle paralysis are rare but can result from continued cholesteatoma growth. If the ABR is normal along that region of the path, the chances of having this tumor are quite small.
If the ear is exposed to sound that is too high pitched or too loud, these hair-like nerves can break off, and they will not grow back. Loud noise at workExposure to continuous loud noise during your working day can make you permanently hard of hearing in the long term. For me, it takes about 3 weeks for my ringing ears to subside after consuming ginkgo biloba. Alternative, you may also use warm olive oil or a couple of sodium bicarbonate drops to soften your harden wax. The area of the eardrum (tympanic membrane) is about 15 times that of the oval window dividing the inner and middle ear.
We recall from earlier lectures that the overtone series for this type of chamber are odd harmonics. TMJ disorders most commonly occur in women between the ages of 30 and 50, but can occur in teens after braces, and in both men and women at any age. Jobs that are hazardous to hearing include construction, the military, mining, manufacturing, farming or transportation.
Once the wax are soften, you can easily flush them out by having your ears gently syringed.
The overtone content (amplitudes of the odd harmonic overtones) can be adjusted by shaping the resonant cavities, forming vocal formants. The ossicles-- three bones called the hammer, anvil and stirrup, also provide about 3x preamplification. The Health and Safety Executive says employers have a duty to protect employees from hearing loss. Injury damage or pressure changesTrauma to the head can impact the ear and cause permament hearing loss.
Sudden pressure changes, like scuba diving or flying, can also harm the eardrum, middle ear or inner ear. While eardrums may take a few weeks to get better, serious inner ear damage may require an operation.
These are called ototoxic drugs, which may cause damage to the inner ear, resulting in hearing loss, balance problems and tinnitus. Antibiotics linked to possible permanant hearing loss include: gentamicin, streptomycin and neomycin. Chronic diseaseSome chronic diseases that are not directly linked to ear issues may trigger hearing loss. Some types of hearing loss are also linked to autoimmune diseases like rheumatoid arthritis. How you hear – anatomy of the earSound causes the eardrum and its tiny attached bones in the middle part of the ear to vibrate.
The spiral-shaped cochlea in the inner ear transforms sound into nerve impulses that travel to the brain. The fluid-filled semicircular canals attach to the cochlea and nerves in the inner ear and send information on balance and head position to the brain.
Growths and tumoursHearing loss can be caused by benign, non-cancerous growths, such as osteomas, exostoses or polyps that block the ear canal. A large neuroma can cause headaches, facial pain or numbness, lack of limb coordination and tinnitus. Loud bangs!Remember, remember the 5th of November – but also remember to take care of your ears on Bonfire Night!
Exposure to loud noise over 85 decibels can cause permanent hearing loss and while fireworks are lovely to watch, some can break that sound limit with a searing 155 decibels. Gunshots and other explosive noises also pack a punch to your ear, in some cases rupturing eardrums or causing damage to the inner ear. Loud concerts and tinnitusThat loud buzzing sound in the ears after a loud concert is called tinnitus. The average rock concert exposes you to sound as loud as 110 decibles which can do permamant damage after just 15 minutes. Other noises that break the 85 decibel range and risk permanent hearing loss include power tools, chain saws and leaf blowers.
Prevent tinnitus and potential hearing loss, which can last days, months or years by using earplugs and limiting noise exposure. Personal music playersIf other people can hear the music you're listening to through your earphones, you may be at risk of permanent hearing loss. A recent survey revealed that over 92% of young people listen to music on a personal player or mobile phone. Recent EU standards limited the sound on these devices to 85 decibels, but many listeners plan to override the new default volume – saying they want to wipe out background noise. Action for Hearing Loss suggests using noise-cancelling headphones rather than pressing override and risking lifelong damage to your hearing. EarwaxIt may be yucky and unsightly but earwax does serve a useful purpose, protecting the ear canal from dirt and bacteria.
However, if earwax builds up and hardens, it can dull your hearing and give you an earache. If you feel your ears are clogged, see your GP or nurse who may suggest olive oil drops to soften and disperse the wax. Don't be tempted to do it yourself with a cotton bud – or any other implement - which only risks damage to the ear.
Childhood illnessChildren are susceptible to ear infections, which are among many childhood illnesses that can cause hearing loss. Usually, infections that fill the middle ear with fluid cause only temporary hearing loss but some may cause harm to the middle or inner ear and lead to permanent hearing loss. Illnesses linked to hearing loss in children include chickenpox, influenza, measles, meningitis, encephalitis and mumps. Born with hearing lossIn the UK, one or two babies in every thousand are born with significant hearing loss. Although congenital hearing loss often runs in families, it can also be triggered by an infection in the mother during pregnancy. Hearing loss can also develop after lack of oxygen or trauma at birth, or if a newborn is premature.
AgeRegardless of how you protect your ears, getting older reduces your hearing as you gradually lose inner ear hair cells. If you are struggling to hear and it is affecting your quality of life, go to your GP or NHS clinic to arrange a hearing test.
