Hearing tests

In our practice, in addition to the audiogram, computer hearing tests are carried out, with which the hearing threshold and the hearing ability can be checked regardless of the employee.


The derivation of otoacoustic emissions (OAE), which can be performed without anesthesia and in a relatively short time of a few minutes, is particularly suitable for a screening examination of hearing in infancy.


With the BERA (brain evoced response audiometry) the nerve conduction speed of the auditory nerve is measured and tumors in this area can be excluded.
