We all know somebody affected by hearing loss, as nearly 1 in 5 Australians live with the condition. Quality of life can be significantly compromised for people with hearing loss and their families.
In contradiction to many people's understanding, hearing loss is rarely similar to the effect of turning down the volume on a stereo. If you feel that your hearing is not what it used to be, or are concerned that a loved one may be experiencing hearing loss - take a couple of minutes to do the online hearing tests provided here.
However, conductive loss accounts for only 10% of all hearing losses, and they range from mild to moderate in severity.
When volume is sufficiently increased, clarity and understanding are usually intact for someone with a conductive hearing loss. Hearing loss that originates in the inner ear is referred to as sensorineural hearing loss or - in laymen's terms, nerve deafness.
While the overall volume of sound may be reduced, the clarity of sounds or voices is also affected.
An example of a mixed hearing loss may be someone with inner ear damage due to exposure to noise in their workplace over many years, who also currently has an infection that has led to a fluid build up in the middle ear. While the ageing process is a major contributor to hearing loss, it is certainly not a condition reserved for the later stages of life.


Not surprisingly, given the impact of noise, males are considerably more likely to have hearing loss than women - including being twice as likely to have a moderate to severe hearing loss.
This graph shown here illustrates the time it takes to cause permanent damage to your hearing when you're exposed to different levels of sound.
Nerves have different sensitivities to deformation of the sensory hair cells within the cochlea.

The extent of the hearing loss varies too, from a mild to a severe hearing loss where loud safety signals may not be heard. The good news is that conductive hearing loss can often be medically treated, and in many cases, hearing can be completely restored.
Other symptoms may also be present, such as ear pain, drainage from the ears, or a feeling of pressure or a blockage. In more than 95% of cases involving sensorineural hearing loss, hearing aids or cochlear implants are the recommended course of treatment.
People with sensorineural hearing loss will often hear people speaking, but can't always understand all the words, even when the volume is adequate. Studies have shown that exposure to noise is thought to be a contributing factor in around 37% of cases of the condition - and interestingly, around 50% of Australians with hearing loss are still of traditional working age (i.e.


This is illustrated through mandatory provision of ear protection on work sites and within factories. A sound that has high frequencies of vibration will excite receptor cells near the opening of the cochlea, while a sound mostly containing low frequencies will stimulate cells at the end of the cochlea. More commonly it is manifested as a difficulty with word understanding, particularly in the presence of background noise.
This can lead to conversations being difficult to follow - particularly in noisy environments where competing background noise 'scrambles' speech and conversations.
Nevertheless, every day millions of Australians are exposing themselves to noise levels that will surely lead to long-term damage to their hearing, including the use of personal stereo systems. Commonly, over time the high frequency hair cell receptors receive more movement by the incoming pressure waves of the fluid inside the cochlea - so are more prone to long term damage than the low frequency hair cell receptors, which are more protected further up the cochlea.
Not unsurprisingly, being able to follow conversations is the single biggest reason that people seek our help.
