Audiology - Localization of disturbances of the auditory system

The audiological functional diagnostics analyses and locates disorders in the complete auditory system. The acoustic noise is led acoustically through the outer, middle and inner ear and is converted into current pulse in the inner ear. These current pulses are led to the brainstem and to the auditory cortex via acoustic nerve. The ear microscopy reveals whether the auditory canal to the eardrum is clear.

Tone and speech audiometry

The hearing is one of the most important human senses. It is crucial for verbal communication. Furthermore, it helps us orientate in our environment and provides us with information on processes we do not see.

But the hearing can be impaired by various reasons and diseases. Hearing tests can ascertain a hearing loss and help find the reason.

Middle ear diagnostics (Tympanometry)

This is the measurement of the acoustic impedance of the eardrum. Here a vacuum is provoked first to be followed by an overpressure in the outer auditory canal. At the same time the changing reflexes of a testing sound are determined. The measurement results are presented by a tympanogram. The function of the tympanometry is to diagnose various diseases of the eardrum, the middle ear and the auditory ossicles.

Otoacoustic Emissions (TEOAE, DPOAE)

At TEOAE (transitory evoked otoacoustic emissions) very short sounds are sent on the ear, and after attenuation it is measured, whether there is a response coming back. At DPOAE (distortion produced otoacoustic emissions) the phenomenon is used, that two continuous sounds, whose tone pitches are in a certain relation to each other, trigger a distorted third sound, so that one can differentiate whether there is a response or not. With the help of the DPOAE only severe hearing disorders can be proven, that is why the TEOAE are mostly preferred. TEOAE are a regular feature of neonatal hearing screening.

Auditory Brainstem Evoked Potentials (ABEPs)

ABEPs for objective retrocochlear diagnostics. The acoustic noise is led acoustically through the outer, middle and inner ear and is converted into current pulse in the inner ear. These current pulses are led to the brainstem and to the auditory cortex via acoustic nerve. At electric reaction audiometry sounds are led to the ear to be examined. Electrodes meter when these current pulses (as potentials) reach the brainstem and later the auditory cortex. This enables to draw reliable conclusions about the area and to what extent the hearing is damaged. The patient is to stay lying down as quietly as possible throughout the complete metering.

Supply with hearing aid

The purpose of a hearing aid is to cure hearing loss symptomatically. Hearing aids are programmed in such a way that the person affected may take the device/s into operation soon and thus understand what is said immediately.
