Hearing Testing – Identify and Diagnose ProblemsHearing testing is an important and effective way todetermine if a patient is undergoing any type of hearingloss or problem. Here are some of the more commontypes of testing and how they are administered.Hearing testing is a way of evaluating the hearingfunction of a person. These tests can help to find out ifthere are problems with different parts of a person’sear. There are several types of hearing tests used.These can include the following:Bedside testing of hearing. These are simple tests to help determine any problems.They can be as simple as whispering to see if the patient can hear that to playingsounds from a tuning fork. These tests can often uncover a problem which needs furtherreview.Audiometric tests. These tests are typically administered by a trained person. Thepatient wears a set of headphones and tones of different frequencies and volume areplayed. As soon as the patient hears these tones, he is supposed to notify thetechnician by raising his hand.This type of test can identify different types of hearing problems in more detail and helpto provide the audiologist with better information so he can make good decisionsregarding treatment.Tympanometry is a test which measures the stiffness of the eardrum and can thereforeevaluate the middle ear effectiveness. It can also help to detect fluid in the middle ear,negative pressure in the middle ear, perforation, or otosclerosis.The test is administered by playing a loud sound and determining if the eardrum stiffenssufficiently based on this sound.Otoacoustic emissions test is relatively new. It can help to assess the hearing responsein newborns and also provides a method for determining if the cochlea is functioningproperly.The test entails placing a probe into the ear canal. This probe contains a tiny speakerand a tiny microphone. When a sound is generated by the speaker it is transmitted tothe inner which stimulates the hairs in the cochlea.
When these hairs are stimulated, they create their own low small sound which isdetected by the microphone. If there is a problem the hairs in the cochlea will notgenerate these ultra low volume sounds.The use of these hearing tests can help to identify potential problems and potentiallyhelp prevent them from getting worse.
