There is no risk.
There are many different hearing function tests. Simple screenings involve making a loud noise and watching to see if it startles the patient. Detailed screenings include brainstem auditory evoked response testing (BAER). This test uses electroencephalogram to detect brain wave activity when sounds are made.
A newer hearing test called otoacoustic emission testing (OAE) can be used in the very young (such as newborns) or when standard tests do not produce reliable results.
