We provide professional support in Audiometry.
Audiometry is the name given to the hearing test that
measures hearing and evaluates hearing functions. It includes tests and
measurements related to hearing.
It is the most common ear test. It determines the
minimum sound intensity (hearing threshold) that both ears can hear at
different frequencies (thin and thick sounds). Anamnesis is taken from the
person and the test is explained to the person. Before starting the pure
tone threshold audiometry test, the person is told to hear different tones of
signal sounds and to press the signal button on his / her hand. After the
test is explained, the test starts. The person is placed in a soundproofed
cabin. Sound is given to the patient’s ear through a headset. The two
ears are tested separately and their hearing thresholds are
determined. When the person hears the sound, he gives a signal by pressing
the button in his hand. Thus, the sound level he hears is
determined. In this measurement, airway and bone conduction hearing level
is determined. Airway measurements provide information about the auditory
pathways from the auricle to the brain. The bone conduit gives information
from the inner ear. By looking at airway and bone conduction measurements,
information about which part of the ear the hearing loss originates from is
obtained. Airway thresholds are determined with the help of headphones
worn on the ear, and bone canal thresholds are determined with the help of a
bone vibrator placed on a protrusion called the mastoid. After the hearing
thresholds are determined, the thresholds are marked on the audiogram.
The test that uses the human voice as a stimulus is called Speech Audiometry. While doing speech
audiometry, a microphone is given to the person and the person is asked to
repeat the words I read. After the test explanation is done, the test
starts. In addition, these test results provide important information
about determining the need for a hearing aid and how useful it can be. These
are important scores to be evaluated regarding the type and model of the
hearing aid to be applied. SRT SDS, UCL, MCL values are determined and the results are recorded and
transferred to the computer.
