Hearing Test

A hearing test measures your threshold of hearing at all the different pitches that lie in the range of speech. Your threshold is the level at which you respond at 50% of the time.  The behavioural measure of hearing is a very accurate measure of what you can hear.  It is often graphed on a chart called an audiogram. From this chart, it is possible to illustrate what parts of speech may be inaudible for someone with hearing loss.

 

The Impact of Hearing Loss on Speech Understanding

The natural decline of hearing is termed presbycusis. It is the most common form of hearing loss which primarily affects the higher pitch sounds. These high frequency sounds is what make up most consonant sounds such as “s”, “f”, “sh”, “t” which bring clarity to a message.  As such, presbycusis affects our ability to understand speech clearly…as a result, people with hearing loss complain that “…everyone seems to mumble!” or “…I can hear, but I don’t understand what people are saying.”

 

Warning Signs of a Hearing Impairment

  Yes No
Do speech and other sounds seem faint and are often muffled?
Do you have difficulty in understanding someone speaking from a distance?
Do you have difficulty conversing in areas with noisy backgrounds?
Does speech and other sounds seem distorted, slurred or lack clarity?
Do you have difficulty in understanding speech even though it may be clear enough?
Do you family complain that the television is turned up too loudly?

Do you often ask for repetition?

Do you have difficulty conversing in the car?
Do you not communicate unless facing the speaker?
Do you not hear the doorbell or telephone ring?
 

If you answer “yes” to two or more of the above, it is recommended that you have your hearing tested.
