Otowave 302 & 302+

Compact desktop tympanometers

Desktop tympanometers designed for fast and accurate middle ear measurements for audiology, ENT and primary care professionals.

The Otowave 302 includes the perfect test array to assess all ages and identify the most common middle ear pathologies; these include 226Hz probe tone frequency, ipsilateral and contralateral reflex testing.

The Otowave 302+ offers quick and accessible test settings with the additional feature of selecting patient profiles including adult, child and neonate. Unique user defined test profiles can be saved for routine testing.

Screening and diagnostic testing

These tymapnometers are suited to screening and diagnostic requirements and have been designed with the key test batteries required for fast and efficient testing. Utilising the clearly laid out keys and display, the operator is easily able to define test settings, monitor progress during the test and evaluate results.

The handheld probe allows for accurate placement within the ear canal and allows for easy results measurements, especially on younger subjects (e.g. identifying Otitis Media). The integrated LED’s inform the operator on next action steps ensuring that the focus is maintained on the patient at all times.

Define your settings and routine

Test settings and routines can easily be changed depending on your preference or test subject in question.
The Otowave range allows you to quickly define the following test settings:

Probe tone (226 Hz high frequency (1kHz) included with Otowave 302+ model)
Sweep speeds 
Ipsilateral reflex frequencies
Contralateral reflex frequencies
Frequencies and test levels follow on routines
Adjustable peak definition for tympanograms (air pressure) 
Adjustable pass/refer criteria for reflex measurements with automatic detection.


Neonatal test functionality

The Otowave 302+ adds extra testing capability by adding 1000Hz probe tone for testing infants under (six months) with advanced results analysis (scalar, vector and component measurements; admittance (Y), susceptance (B), conductance (G)).

When testing subjects of different ages or needing to quickly switch through different test routines, switching is made easy with the Otowave 302+ by allowing switching between six test profiles at the press of a button. Three test profiles for adult, child and neonate are includes with three customisable profiles available for your needs.
