Building on the success of the Otowave 102, the Otowave 202 adds in contralateral reflex testing as well as optional high frequency testing for neonates (202-H).

The Otowave 202 is the perfect instrument to help audiologists and hearing aid dispensers identify middle ear disorders, but also to differenciate conductive and sensorineural hearing issues in combination with an audiogram.
