Tests For Hearing
Hearing loss is best treated when it is still in its early stages, but in order to do this detection will have to be done first. Some things that can cause hearing loss are diseases, illnesses and bing bumped on the head. A person can be born with hearing disabilities, if parts of the ear do not form properly.
Hearing loss in babies are a very common thing, as hearing loss happens all the time in babies. It doesn’t matter if a person is 60 or 6 years old, he or she can lose the sense of hearing no matter what. Just because a person is born normal, he or she can still get it from sustaining head injuries or a person’s genetics.
A person who is subjected to loud environmental noises day in and day out is likely to lose their sense of hearing. A person whose house is near an airport is subjected to regularly loud noise that is damaging to the person’s ears. Power tools are machinery that emit loud levels of noise and protective hearing equipment should be worn to avoid damage.
Physicians and specialists will often times give hearing aids to a patient suffering from hearing impairment. Each kind of hearing aids will have their own advantages and disadvantages. Any kind of hearing aid will basically still just gather and magnify surrounding sound to the user.
Hearing tests should always include the use of an audiometer to detect a person’s sensitivity to sound at different frequencies. Tests with an audiometer involve a person sitting in a soundproof booth wearing headphones that are connected to an audiometer. The physician or attending technician works the audiometer so that the patient hears different decibel level sounds and frequencies.
The subject inside the booth, upon hearing the tone will usually acknowledge hearing the tone by pressing on a button. As the test goes on, the audio specialist plots the points on a graph of frequency against loudness. Once the test is complete, a simple view of the graph can easily reveal if the subject does indeed have hearing loss and at what frequencies and decibel levels.
The audiometry hearing test does not determine the type of hearing disorder, but the Weber and Rinne tests do. Tuning forks are used by the specialist on the subject to determine the extent of hearing loss. Weber tests can check if a person has hearing loss but not the type, while the Rinne test can determine which type and in what ear.
With the Weber test, the tuning fork is placed in the exact middle of the forehead. The patient will either hear unequal sound in the ears, which means hearing loss in one of the ears or equal sound meaning no hearing loss or equal hearing loss. When a person does not hear the same sound in both ears then it can be concluded that the person has definite asymmetric hearing loss.
The Rinne test is administered after the conclusion of the Weber test, to find out which type of hearing loss is present. The type of hearing loss and in which ear can also be determined by the tests. These tests are the easiest and fastest way of diagnosing hearing loss.
