Notes: What they are doing is they are amplifying sound level to overcome mismatched impedance.
This 1-minute video gives a quick overview of the anatomy of hearing, and the causes and types of hearing loss. Conductive hearing loss is caused by any condition or disease that blocks or impedes the movement of sound through the outer or middle ear.
Generally, we can treat the cause of a patient’s conductive hearing loss, giving them complete or partial improvement in hearing. A mixed hearing loss is a combination of conductive and a sensorineural hearing loss in the same ear. Even in our clinic, we have noticed that compared to 10 years ago, where we mostly saw pensioners and the age groups from 80+, now we are seeing more and more clients who are concerned about their hearing from 40+ age.
It is really important to be proactive about hearing loss and get it tested as early as possible to prevent auditory deprivation. Conductive loss is generally caused by a problem in the outer or middle ear which stops sound being passed through to the inner ear and nerve fibres.
Sometimes surgery such as a tympanic graft can fix the hole, otherwise a hearing aid may be required. If this progresses to the next stage, fluid is then secreted into the middle ear space and the eardrum becomes red, bulging and inflamed. Medication and antibiotics are usually required, although sometimes a chronic ear infection can remain which has to be monitored and hearing loss helped through a hearing aid. Sometimes a build up of calcium on the middle ear bones can cause them to fuse and then not move as they should to pass the sound on through to the inner ear.
This is a genetic condition usually affecting women and can occur at times of hormonal changes such as pregnancy or menopause. Being exposed to loud noise, especially over extended periods of time can affect the tiny inner ear hair cells of the cochlea. However repeated exposures to the loud noise, such as working with machinery, factory noise or tools, the little hair cells can no longer recover. A typical complaint of a person with a high frequency noise induced hearing loss is being able to hear people  talking but not all that clearly, particularly in background noise. The sooner you act on this kind of hearing loss by wearing properly fitted hearing aids, the better you can save your ears by stimulating the remaining hair cells to keep active.
Also, being very mindful of wearing ear protection in loud noisy places can help protect your hearing (eg Clipsal, concerts). Unfortunately, as we get older our bodies get a little worn out and this includes the ears. It is really important to stimulate the remaining hair cells to prevent further loss just from Auditory Deprivation.


Meniere’s Disease is caused by excessive fluid in the inner ear and balance organs of the ear.
Meniere’s Disease  can exist for quite  a long period of time with varying severity, and eventually reaches the ‘Burnt Out’ phase where symptoms are stable but the hearing is permanently damaged. Usually the hearing loss is a low frequency or flat hearing loss which can make things sound softer overall but also create distortion. Being checked by an ear, nose and throat specialist is important in this case with hearing rehabilitation through us happening afterwards or alongside medical evaluation. If this does occur, you are best off seeing your GP as soon as you possibly can, because in some cases immediate steroid and oxygen use can help. People with hearing loss related to ototoxic medications are usually successful with hearing aids.
A mixed hearing loss can result from a combination of middle ear and inner ear problems, such as a ear infection as well as a noise induced loss.
We are happy to write referral reports and do so for any cases we recommend medical checking. The arm of the malleus is attached to the eardrum, and the footplate of the stapes is attached to the oval window of the cochlea (inner ear). What they are doing is they transmit vibrations of the eardrum into the cochlea. While this might have been true many years ago, with modern advances in technology, nearly 95% of people with a sensorineural hearing loss can be helped with hearing aids.
It is not the hearing aids that make one look older, it is what one may believe they imply. It uses animation to help you understand how you hear, and what may be happening when your hearing is no longer top-notch.
Please see act sooner rather than later for more interesting information on preserving hair cells and keeping them healthy. It basically acts to help protect the ear by trapping any foreign things present in the ear canal. Usually people with perforated eardrums should be very wary of getting water in their ears.  We can make custom swim plugs for use with showering or swimming to protect the ear if a perforation is evident. Typically the eustachian tube (which is the tube that opens when you are flying in an aeroplane and your ears ‘pop’) jams shut preventing air from getting in to the middle ear cells. Each time the ear is exposed to loud noise, the little inner ear hair cells get knocked flat by the sheer force of the vibrations that are sent through the eardrum and middle ear bones onto the cochlea. This is called Permanent Threshold shift and the end result is a permanent high frequency hearing loss. This is due to the damage to the tiny hair cells which can no longer process sound properly and have trouble if there is competing noise in the background. We can make custom ear plugs which allow a pleasant listening experience but at safe levels for your ears.


Generally the high pitches tends to be lost first as they are the most activated in the first turn of the inner ear. This can result in quite debilitating symptoms like loss of balance, fluctuating hearing loss, tinnitus and a feeling of fullness in the ears.
The actual cause of Meniere’s disease is not known but factors such as genetics, auto immune and viral influences have been linked with Meniere’s Disease.
The cause is generally unknown although many cases of sudden hearing loss are caused by an interruption of the blood supply to the tiny hair cells of the inner ear. These are called ototoxic medications and there are about 200 medications currently that are considered ototoxic. Usually an ear, nose and throat specialist evaluation alongside our tests and a fitting of hearing aids is recommended. Since most people with hearing impairments hear well in a quiet environment like a doctor’s office, it can be virtually impossible for your physician to recognize the extent of your problem. If you miss a punch line to a joke, or respond inappropriately in conversation, people may have concerns about your mental acuity, your attention span, or your ability to communicate effectively.
If hearing aids help you function like a normal hearing person, for all intents and purposes the stigma is removed.
However sometimes wax can build up to the extent that it becomes hard, black and blocks the entire ear canal. The eardrum then gets sucked back so it does not move well and you feel as though you are quite deaf. Usually the condition that the medicines are used for, such as cancer, heart disease and serious infections are more severe than hearing loss and it is a risk worth taking if indicated by your doctor. This ensures that any medical or surgical intervention  can happen as well as hearing aid rehabilitation if needed.
Without special training and an understanding of the nature of hearing loss, it may be difficult for your doctor to even realize that you have a hearing problem. It also reduces the intensity of sound, but may also result in a lack of clarity even when sounds, particularly speech, are loud enough. At a simplistic level, untreated hearing loss means giving up some of the pleasant sounds you used to enjoy. We can treat patients with sensorineural hearing loss with amplification through hearing aids. This is exactly what happens when you have been at a loud concert and afterwards you feel ‘deaf’ with ringing in your ears, but by the next morning, your hearing is back to normal.
