If you find that you have to have the television louder to hear it, or you need people to repeat themselves so that you can understand them, you may want to consider having a hearing test performed. This allows the audiologist to test whether or not the auditory system is working properly.
When a person with normal hearing screws sounds, the vibrations that are made by air, fluid, and other things in our environment create sound waves. These are sent through the auditory canal at a certain speed that determines how well you hear the sounds as they travel through the middle ear, inner ear, nerves, and brain.
The first thing that occurs in the process of hearing is the sounds entering the outer part of the ear and bouncing on the eardrum, which separates the outer from the middle ear. The eardrum vibrates as the sounds hit it, which sends the sound waves to the three bones in the middle ear '. They vibrate into each other and increase the sounds as they go into the inner ear. When it reaches the inner portion of the ear, the nerves take over and create impulses, which then go to the brain where they are interpreted into sounds. This whole process takes less than a second.
There are several times in our lives that hearing tests may be performed. Babies are screened soon after birth so that the doctors can determine whether or not he or she has a hearing problem. Hearing problems can hinder the development of speech, learning abilities, and language comprehension. Each state in the US requires a hearing test for all hospital born babies.
When your child enters kindergarden and reaches other school milestones, he will usually have a hearing test done to make sure that there are no hidden problems. These will usually occur at child check-ups that are performed every year to every other year. Sometimes hearing problems are linked to various learning and discipline problems.
As an adult you will have your hearing screened at your yearly physical. Someone who has not noticed a hearing loss will be evaluated through use of a hearing test. Senior citizens will be evaluated at their physicals for age related loss to their hearing. Anyone who works at a job where they are exposed to loud noises on a day-to-day basis will undergo testing.
If you think you need a hearing evaluation, see your doctor for a referral to an audiologist who will perform a series of hearing evaluations to find out the amount of your hearing loss so that you can have it treated.
