Hearing tests

The hearing threshold is checked using an audiometric test. The test is carried out in a soundproofed room and acoustically treated.

In the first part of the test, headphones are placed on the ears that play a series of variable sounds and frequencies. The subject must indicate when he hears a sound - even if it is extremely weak. Each ear is tested individually. The test examines what is the minimum hearing threshold. If it becomes clear that hearing thresholds are lower than the norm, the reason for this should be ascertained. The problem may be in air conduction (as a result of injury to the outer or middle ear) or neuronal conduction (as a result of injury to the inner ear or even the brain).

Once it becomes clear that there is a hearing problem, do the second part of the audiometry test, where the sound is transmitted from a device placed on the bone behind the ear. In this way the sound waves bypass the orbital path through the outer and middle ear and are transmitted directly to the auditory organ in the inner ear through the skull bones. This test examines the neural transmission pathway, also known as "bone walking."

If it turns out that the bone is functioning properly, it can be concluded that the hearing problem is due to a disorder in the air. And if it turns out that bone marrow is abnormal, it can be concluded that this is a neural problem. However, there is also the possibility that this is an integrated problem: of air conduction and neural injury.

The results of the tests are shown on a graph showing the range of hearing - in terms of power and frequency - in each ear and in each of the tracks.

In addition to these tests, a test will be conducted that tests your ability to discern syllables and words. In this test, called "Speech Hearing Threshold Testing", you will be asked to repeat a series of simple words played with increasing intensity.

When examining the tympanometry - measured the movement of the eardrum, the test helps to detect the presence of fluid in the middle ear.

The tests are saved and printed by unique software - AudioTest
