Hearing Tests And Who Should Receive Them
An audiologist, a professional who can test a persons hearing levels,[link widoczny dla zalogowanych], should be sought if you ever feel that your hearing is getting worse. Hearings tests try to locate the causes of any hearing loss as well as testing the person's current level of hearing. After reading this article you will know what to expect from a visit to an audiologist and the tests that they are likely to perform.

You should be prepared to give details concerning your medical history. Questions during the history might include inquiries about the type of work you do and the sounds you are exposed to while on the job. The audiologist will want to know of any injuries you may have suffered and past illnesses that may have had an effect on your hearing.

Because hearing loss can be genetic you may be asked about other family members and whether they too have suffered from hearing loss. During the medical history,[link widoczny dla zalogowanych], the audiologist might also take a look inside your ears, using an instrument known as an otoscope. With it they can see whether there are any visible signs that could indicate damage to the eardrum or inner ear.

Any hearing examination will probably involve an audiogram in a sound proofed room using specialized equipment. This requires you to wear specialized audio headphones in the room. During the test, sounds are played and the audiologist will make a note of the lowest tone that you can hear. A lot of people are tested in a similar way when they were at school. The principle is the same but may well involve more sophisticated equipment.

Another test called a tympanometry is likely to be carried out which involves a gentle pressure probe being placed in the middle ear. A tone is played whilst the device gentle raises and lowers the air pressure inside the ear. The tympanometry is carried out to see whether there are any disorders or the presence of fluid inside the ear.

Hearing loss can also be determined by the use of a tuning fork. If placed next to the patient's ears the tuning fork makes the middle ears to vibrate. Next,[link widoczny dla zalogowanych], the fork is placed on the bone behind one of the patient's ears which send the vibrations through to the inner ear. It is important to establish whether one of the tomes appeared louder to the patient. The patient's hearing range and the precise location of any hearing loss can be determined by carrying out this kind of test.

Another common test to determine the part of the ear that is causing the hearing loss is the 'site of lesion' test. This test can allow the audiologist to compare the hearing in the patient's ears when other sounds are detected. The site of lesion test uses the same equipment as an audiogram,[link widoczny dla zalogowanych], but the equipment is used slightly differently to provide a variety of results.

The audiologist is likely to suggest other medical examinations to establish whether any other medical conditions are present which are causing the loss in hearing. Taking a special x-ray of the brain and inner ear can allow the nerves associated with hearing to be examined.

A series of tests is sometimes required to get an accurate diagnosis so that the appropriate treatment can be recommended. Patients often go on to lead much better lives due to the effective treatments available and the accurate diagnosis provided by the variety of different hearing tests that are available.
