Whilst there are many reasons for hearing loss, the condition itself falls into two main categories: Conductive and Sensorineural. Conductive hearing loss is caused by any obstruction that prevents sound waves from reaching the inner ear.
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.
Amongst all the tests that can be performed on your hearing, pure tone audiometry is the most common. 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. At a basic level a hearing instrument or hearing aid is an electronic, battery-operated device that amplifies sound. In recent years hearing professionals have seen large changes, not just in what hearing devices can do, but how they are worn.


Tinnitus is actually heard by most people at some point in their lives, even those with normal hearing. Hearing aid users have more energy, participate in the conversation, look like super heroes and fashionistas and are role models for good health. Contributed by Debbie Clason is a staff writer for Healthy Hearing and has a master's degree from Indiana University. When measured together by your hearing healthcare professional, dB and Hz tell the degree of hearing loss you have in each ear.
Based on the outcome and the lifestyle information you provide, the hearing healthcare professional will be able to recommend a course of treatment, which may include the purchase of hearing aids and enrollment in aural communication classes.
The following is a guide to hearing that covers many of the questions I receive on a regular basis about all things hearing. 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.
If you can hear sounds across a range of frequencies at 0-20dB you are considered as having normal hearing. Technically speaking, it’s defined as having hearing loss between 26 and 40 dB in the speech frequencies.
The outcome of the evaluation is known as an audiogram, a graph of the softest sounds you heard during your test. Keep in mind, untreated hearing loss puts you at risk for developing a host of other health-related problems, including depression, dementia and Alzheimer’s disease.


On second thought, maybe you can use the 19kHz frequency to tell if someone is lying about what she can and can't hear (we all know that person who would cheat on a hearing test). 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. 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. Your family physician may be able to refer you, or you can visit our online directory and find a trusted professional in your community. 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.
