In the example below, the person has moderately severe high-frequency hearing loss that is slightly worse in the right ear. Audiometry is necessary to confirm a hearing deficit because physical tests of hearing, such as the whispered voice and the finger-rub test, are not as reliable.20 Office audiometry is sufficiently sensitive and specific to serve as a screening method.21 Screening audiometers for office use generally test at several frequencies in the speech range between 500 and 4,000 Hz.

Limpness blocks sound in a different way. Unless you were involved in research, most audiologists do not think of this information as clinically useful. Someone with high frequency hearing loss has trouble hearing sounds in the 2,000 to 8,000 Hz range. Infections of the middle ear have the potential to cause a buildup of fluid and temporary hearing loss.
