Thank you for purchasing an Amplivox Otowave 302, a desktop controlled impedance meter that will give many
years of reliable service if treated with care.
This operating manual applies to the Otowave 302 which is available as a standard option (with 226Hz probe
tone) and as an H-option (1000Hz probe tone in addition).
1.2. INTENDED APPLICATIONS
This instrument is designed for use by trained personnel only, such as audiologists, ENT surgeons, doctors,
general practitioners, hearing aid dispensers, child health professionals and hearing healthcare professionals

knowledge and training.
The Otowave is to be used to obtain information on medical and functional conditions of the middle and outer

on all ages and performs the following kinds of measurements:

Tympanometry: To measure the compliance of the tympanic membrane and middle ear at 226 or
1000 Hz over a range of pressures.

reflexes. The tests are performed either at ambient or peak pressure, based on the outcome of the
tympanometry.
