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.

Noise is a sound which is unwanted and has disagreeable musical quality, which is unwanted sound at the wrong place and at the wrong time. Noise pollution is defined as the disturbing or excessive noise that may cause harm to the activities and balance to human or animal life. Some of the effective solutions to control noise pollution are as follows:Plantation of plant bushes and trees around the sound generating sources. Sounds are air pressure variations that are typically a mixture of random, impulsive, and tonal components. We describe these sounds by their respective frequency or frequency range, loudness, and duration. Another problem is that perceived loudness tells us nothing of the harmful or dangerous nature of the sound. Noise regulations in Scandinavia and the EC take a much more proactive approach to noise regulations. The most important lesson from the history of noise measurement and regulation is that new regulations and standards should not be built from old ones.
A practical, solutions-driven reference, Safety Engineering, 4th edition, has been completely revised and updated to reflect many of today’s issues in safety. 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.

It also caused from industrial installation, construction sites and fixed recreation facilities. NIOSH reports that an estimated $242 million is spent annually on workers’ compensation for hearing loss disability. Harmful aspects of sound exposure relate to physiological concerns such as hearing loss and heart damage.
This puts commercial technology developers in a difficult position because it is commercially risky to invest in a new technology in the hopes that they will eventually be added to an acceptable controls list. The Scandinavians have adopted the use of alternative weighting scales for industrial workplace settings. Measurement standards should be appropriate for the noise levels and spectral content specific to the environment being regulated.
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. The Department of Veterans Affairs spent an estimated $1.39 billion in calculated compensation for major auditory disabilities in FY2010. Dangerous aspects of sound exposure relate to safety concerns such as noise-induced fatigue, interference with communications, etc.
The continued re-adoption of the Walsh-Healy Act has been at the expense of the hearing of many American workers.
It was left to the user to choose the appropriate scale based on overall loudness level (A for quieter environments, C for louder environments). This means that the valid measurement of LFN is of critical importance to workplace safety. 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.
Prolonged exposure to high levels of noise proves harmful and may cause hearing loss and other effects like interfernce with speech, communication and sleep. Since then, we have seen a steady stream of federal regulations and private standards dictating the use of the A-weighting scale in increasingly loud and low frequency-dominant environments. Additional protections such as active ear defenders should be considered in the cases for true protection of workers. The effects of noise depends on the intensity of sound waves, frequnecy of sound, age and health characteristics of an individual. The unit of measurement of intensity of sound is in decibel (dB).
