The rate at which a sound vibrates is called its frequency and the higher the frequency the higher-pitched the sound, such as a piccolo or birdsong. Loudness varies from person to person and as such it would help to mention here how loudness is described: inaudible, very soft, soft, moderate, loud, very loud or too loud. Our ears are divided into three parts – the outer ear, the middle ear and the inner ear. The outer ear includes the pinna (also called the auricle), the ear canal and the eardrum (also called the tympanic membrane).
The middle ear is an air-filled chamber connected to the nasal and throat passages by the Eustachian tube which equalises air pressure on both sides of the ear drum. The inner ear is filled with a fluid and consists of the spiral shaped Cochlea, named from the ancient word for the shell of a snail. Whilst there are many reasons for hearing loss, the condition itself falls into two main categories: Conductive and Sensorineural.
It is quite possible for a conductive hearing loss to occur together with a sensorineural hearing loss. A common cause of hearing loss is caused through prolonged exposure to harmful sound (noise) or a sudden brief but intense noise like an explosion to the ear.
One way we can prevent hearing loss is by staying in environments with safe sound limits. Occupations particularly at risk of hearing loss due to exposure to noise include fire fighters, police officers, factory workers, farmers, construction workers, military personnel, heavy industry workers, musicians, and entertainment industry professionals. Your hearing healthcare professional will usually begin by asking you questions about the health of your ears and general health and your lifestyle. A physical examination of your ears is performed to eliminate any medical problems such as infections or blockages such as wax. Amongst all the tests that can be performed on your hearing, pure tone audiometry is the most common. This piece of specialised equipment produces tones at specific frequencies and levels to each ear independently.
At the end of a hearing test you may be told that you have normal hearing or a mild, moderate, severe or profound loss of hearing.
How people classify themselves relative to hearing loss is a very personal decision and reflects much more than just their ability to hear. In recent years hearing professionals have seen large changes, not just in what hearing devices can do, but how they are worn.
This device is housed in a small, usually curved case behind the ear and the sound is delivered into the ear canal via a custom-made earmould or tubing system. Along with ITCs and ITEs, CICs are considered to be more modern and cosmetically appealing CICs fit so deep in the ear canal that they are practically invisible. Tinnitus is actually heard by most people at some point in their lives, even those with normal hearing.

RehabilitationCochlear implant users of all ages can practice speaking and listening skills with interactive and downloadable (re)habilitation activities. Any problem in the outer or middle ear that prevents sound from being conducted properly is known as a conductive hearing loss. Sensorineural hearing loss results from missing or damaged sensory cells (hair cells) in the cochlea and is usually permanent.
Mild to severe sensorineural hearing loss can often be helped with hearing aids or a middle ear implant. A problem that results from the absence of or damage to the auditory nerve can cause a neural hearing loss. Hearing aids and cochlear implants cannot help because the nerve is not able to pass on sound information to the brain. The following is a guide to hearing that covers many of the questions I receive on a regular basis about all things hearing. A healthy ear is able to pick up vibrations that are measured in a basic unit of frequency known as Hertz or Hz.
Sound waves travel through each part of the ear to the brain where they are analysed and interpreted into meaning. The passageways of the cochlea are lined with over 15,000 microscopic haircells (called inner and outer hair cells) that convert sound vibrations from the ossicles into nerve pulses which are then sent to the brain. Hearing loss can also be attributed to a combination of both types – a mixed hearing loss.
The nature of noise-induced hearing loss is sensorineural, and at present, can only be helped and not cured. Results are instant, and you will know immediately if you do have a hearing problem and what steps to take.
Otoscopy is an examination that involves looking into the ear canal with the cone of an otoscope.
The patient will communicate that they have heard the tone by either raising their hand or pressing a button.
If you can hear sounds across a range of frequencies at 0-20dB you are considered as having normal hearing. This could cause depression or cause people to withdraw from group or social situations due to a sense of lack of control and intimacy with friends and family. In a digital device, sound is received through a microphone and then converted into electrical signals.
These changes can be attributed to a reduction in the size of components, increased durability and cosmetic concerns on the part of the wearer. As tinnitus can be a sign of certain medical complications, it should never be dismissed or underestimated. I am constantly adding to the information featured here based on your feedback and questions. The ear converts vibrations into electrical signals sent to the brain, where they are translated into meaningful information such as speech and music.
The human ear is designed to be a receiver of sounds but also plays a major role in balance and body position. Sound reaching the eardrum causes it to vibrate, transmitting that sound to the three smallest bones in the body. The auditory nerve contains thousands of nerve fibres that help our brains interpret these pulses into meaning. Most of us can sustain noises of 90 decibels for up to eight hours without permanent damage, for example, but at 100 decibels the maximum time is only two hours.


Musicians, for example, wear custom-fitted earplugs that do not distort music or impact performance. A set of headphones is worn over the ears or foam earphones placed in the ear canal; and you may be required to sit in a sound-proof test room. As the test progresses, the hearing professional will plot results on an audiogram where the frequency is on the horizontal axis and the loudness is on the vertical axis.
Hearing impaired people with partial loss of hearing may find that the quality of their hearing varies from day to day, or from one situation to another or not at all. There can also be a negative effect on people’s perceptions of you, which often manifests itself as the idea that you may be somehow less intelligent. A tiny amplifier increases the loudness of the signals, transmitting them back to sound through a speaker into the ear canal.
Individuals can report intermittent episodes that are not very bothersome, to a constant tinnitus that can negatively influence daily life. It can also happen spontaneously without any reason, and then disappear as strangely as it began.
This process ensures that without your approval, data will not be transferred to the social networks.
Speech, for example, consists of vibrations at different volumes and numerous frequencies and most are between 250 and 8000Hz.
Excessive noise exposure can happen unknowingly at home in the form of music on an MP3 player, for example, or as a by-product of the workplace environment. Once they have sought that initial help they find the subsequent process straightforward and altogether life changing.
Once each frequency has been tested and plotted, the points are joined by a line so that you can easily see your results and compare them to what is considered to be within normal limits. Other signal modifications can also be done within the digital chip to improve the sound quality, particularly of speech sounds. BTE designs have become smaller and smaller over the years, and the introduction of so-called receiver-in-the-canal products have contributed to this development. These tiny ossicles amplify the vibrations and direct the waves of sound into the inner ear.
But you are not alone - although aging causes our ears to deteriorate, 20% of all 40 to 60 year olds also have some form of hearing loss. The good news is that if you are worried about a hearing loss, solutions that will enable improvements are now available.
It is when tinnitus starts to negatively affect one’s life that further consultation may be necessary. For example, you might have difficultly determining where a voice is coming from when addressed from your deaf side. Our ears are most sensitive at the 2000-5000Hz range which is important for speech and where continuous exposure to noise causes the most damage. However, a lack of knowledge and social stigma prevent many from being helped by simple, effective solutions.
