How a Hearing Test Works




Many of us fear going for various medical tests and exams because we are not sure what the procedure entails. A hearing test, on the other hand, is a fairly standard and simple procedure, and should be done by anyone who may have a hearing impairment. But what exactly does a hearing test do? Well, it evaluates the sensitivity and accuracy of your hearing, determining what type of hearing impairment you may have. This test is performed by licensed audiologist, who is the only professional qualified to conduct such a test. The test is pretty straightforward. Your audiologist will firstly try to gain some insight into your history with hearing impairments. Questions that he may ask will revolve around typical noises you are always exposed to, including how loud and how often they occur. These are typical questions and aims to help the hearing aid audiologist find possible causes of the damaged hearing.Questions about past illness may also be raised. This is because various illnesses are often linked to hearing loss. This will help the hearing aid audiologist devise the most accurate solution possible.The hearing aid audiologist will also look inside your ear with an otoscope, which is a small cone shape scope with a light at the end. This device helps to see inside the ear and check if there is anything damaged.You are then required to sit in a soundproof booth wearing earphones or ear plugs, which is connected to an audiometer. The audiometer produces sounds and tones of different levels and frequencies, which is transmitted to each individual ear. The hearing aid audiologist charts the loudness on an audiogram, which is a graphical representation of how well your ear responds to different levels of frequencies. While still sitting in the booth, you are asked to raise to raise your hand or press a button whenever you hear the sound being sent to your ears.The hearing aid audiologist records all the information he receives and analyses it. The extent of your hearing loss is based on which frequencies you could or could not hear. A hearing test is vital if you are thinking about fitting in a hearing aid. This test measures the level of your hearing impairment and determines what type of adjustments the hearing aid needs.Having a hearing test done is not a big deal, and should be conducted if you have any sort of hearing impairment.--Angela Beckham is from the UK writes on matters relating to deafness and hearing impairments.
