Hearing impairment, deafness, or hearing loss refers to the inability to hear things, either totally or partially. Hearing loss refers to a diminished ability to hear sounds like other people do, while deafness refers to the inability to understand speech through hearing even when sound is amplified. Degree of hearing impairment - a person's severity of hearing impairment is categorized by how much louder than "usual levels" sound volumes need to be set at before they can detect a sound.
Degree of deafness - any degree of deafness means the person cannot understand speech through hearing at any level of amplification. Sound waves enter the ear, go down the ear canal (auditory), and hit the eardrum, which vibrates. This means that the vibrations are not passing through from the outer ear to the inner ear, specifically the cochlea.
The ossicles may be impaired due to infection, trauma, or their fusing together (ankylosis). Hearing loss is caused by dysfunction of the inner ear, the cochlea, auditory nerve, or brain damage.
Long-term exposure to loud noises, especially high frequency sounds, is another common reason for hair cell damage. Sensorineural total deafness may be due to birth defects, inner ear infections, or head trauma. On the next page we look at prelingual deafness, post-lingual deafness and unilateral and bilateral deafness.

On the inside of the eardrum, the middle ear is open to the throat at the back of the mouth through the Eustachian tube, which equalizes air pressure on each side of the eardrum. All hearing losses can be divided into two general groups, based on where in the ear the loss originates from, namely sensorineural and conductive.A  Hearing losse can also be a combination of conductive and sensorineural types.
Sensorineural hearing loss involves deterioration of the delicate hair cells in the inner ear or nerve pathway to the brain. Noise exposure: A can result from a single incident or prolonged exposure to excessive noise a€“ military and sport firearms, industrial and home machinery, music concerts, i-pod. You have difficulty understanding conversation in a noisy restaurant, crowded room, or large group.


A professional hearing evaluation will be conducted by a hearing care professional (audiologist or hearing aid acoustician) using calibrated audiometric equipment.
Case history : to gather information with regard to the individuala€™s difficulties andA  concerns about hearing, medical history, previous hearing assessments and treatment , and the impact of hearing loss on the individuala€™s personal, social and vocational functioning. A comprehensive audiology test battery, tailored to suit the age and co-operative abilities of each individual, will be conducted. Recommendation of treatment solutions, A including referral to an Ear, Nose and ThroatA  specialist or general practitioner if a conductive hearing loss has been detected, or, in cases of sensorineural hearing loss, hearing instrument recommendation based on the persona€™s hearing needs, lifestyle,A  personal preferences and budget. Tinnitus is often described as ringing, buzzing, hissing, roaring or whooshing noise, which in over 95% of all cases, is only audible to the person concerned. Most professional tinnitus management methods use a combination counseling and sound stimulation. A patient with mild hearing impairment may have problems understanding speech, especially if there is a lot of noise around, while those with moderate deafness may need a hearing aid. Profound deafness means the person cannot hear anything at all; they are unable to detect sound, even at the highest volume possible.
The vibrations from the eardrum pass to the three ossicles (bones called the malleus (hammer), incus (anvil) and stapes) in the middle ear.
It can be due to an excessive build-up of earwax, glue ear, an ear infection with inflammation and fluid buildup, a perforated eardrum, or a malfunction of the ossicles (bones in the middle ear).
If the ear drum and middle ear are functioning properly, patients may benefit from a cochlear implant - a thin electrode is inserted in the cochlea, it stimulates electricity through a tiny microprocessor which is placed under behind the ear, under the skin. If the tube gets infected and becomes blocked by mucus, pressure builds up on one side or the other, and the eardrum bulges, causing pain.
A While there is no cure for A sensorineural hearing loss, in most cases (90%) hearing aids will help. If the hearing test results indicate that you have a conductive hearing loss, you will be referred to an Ear, Nose, and Throat specialist of your choice for medical intervention. It is essential that you contact an audiologist or hearing aid acoustician who will test your hearing, explain the results and recommend solutions.
Tinnitus is a chain reaction of perception, emotion and attention and thus involves processes in both the ear and the brain. The perceived sound is typically a mere 10 dB or less (fainter tha a leaf fallingto the ground). People who are born deaf find lip-reading much harder to learn compared to those who became hearing impaired after their had learnt to communicate orally (with sounds). Some people define profoundly deaf and totally deaf in the same way, while others say totally deaf is the end of the hearing spectrum.
These occicles amplify the vibrations, which are then picked up by small hair-like cells in the cochlea; they move as the vibrations hit them, the movement data is sent through the auditory never to the brain.


As humans get older, the hair cells lose some of their function, and our hearing gets worse.
On the final page we take a look at how deafness is diagnosed and the available treatments for deafness and hearing impairment. The sound waves reach one ear a split second before the other and a slightly different pressure.
The amplified vibrations spread through the fluid-filled cochlea and stimulate sensitive hair cells, which converts vibrations into nerve signals that travel along the auditory nerve to the cerebrum of the brain where the sensation of sound is produced. The sacs contain chalky granules, called otoliths or balancing stones, which lie on sensory fibres.A  When your head tilts the otoliths move under gravity, pulling on the fibres .
Because of the gradual development and unaffected loudness, people are often not aware that there hearing is deteriorating. A Its causes are diverse, including hearing loss or inner ear damage, extreme stress or trauma,A  Meniere disease, acoustic neuroma, degeneration of the middle ear,loud noise exposure (including loud music) and certain medications. However, those who suffer from itA  often struggle to explain their problemA  and to be taken seriously by family, friends and co-workers. In Western Europe and North America it is estimated that over half of all people over 70 years of age have hearing impairment caused by degenerated hair cells in the cochlea. Short fibers in the first part of the cochlea respond to high-frequency vibrations, while long fibres in the last part (apex) are sensitive to low-frequency vibrations. The fibres fire a nerve signal which reaches the brain and set off a reflex tending to return the body to its normal posture The semicircular canals contain sense organs that respond to movements of the fluid. The stress caused by hearing loss is often a significant factor behind the tinnitus.A  Hearing and understanding better by wearing aids reduces stress and fatigue. When you rotate your head, the fluid lags behind and bends a jelly-like blob called the copula at one end of the canal. Furthermore the inner ear noises are usually reduced to the surrounding background when external sounds are once again fully perceived.A  Even with hearing loss in only one ear, people profit from a hearing instrument. Tiny hairs rooted in nerve cells at the base of the copula are stimulated to send information about head rotation to the brain. A Sound stimulation can also be delivered by broad-band or narrow-band signals from a noise generating device, environmental sounds and soft, slow paced music. Based on the semicircular canalsa€™ angles to each other, the brain can detect movement in any direction.
