Otowave 302 & 302+

Compact diagnostic tympanometers

Diagnostic tympanometers that provide fast and accurate middle ear measurements for all age groups, including neonates. Ideal for audiology, ENT, and hearing care professionals who require customised measurements and data transfer.

The Otowave 302 includes the perfect test array to assess all ages and identify the most common middle ear pathologies. The Otowave 302+ offers quick and accessible test settings with the additional feature of selecting patient profiles including adult, child and neonate.

Designed for small ears

Conducting middle ear measurements for neonates and children is fast and accurate, with diagnostic information displayed during and after the automatic test. Test settings can be defined according to the requirements of the patient.

With a probe specifically designed for small ear canals, middle ear measurements for neonates and children can be conducted with speed and accuracy. Diagnostic information is displayed via the display during and after the user defined measurement routine.


  • Compact design with a graphic LCD display
  • 226Hz probe tone or 1kHz probe tone (Otowave 302+) with admittance, susceptance and conductance measurements (YBG)
  • Live tymp display - measurements shown in real time
  • Ipsilateral and contralateral reflex frequencies (0.5, 1, 2 & 4kHz)
  • Auto pass/refer evaluation (ear canal volume)
  • Fast and accurate impedance measurements
  • Intuitive use / real time display
  • Optimised, user-selectable measurement speeds
  • Six user-configured test protocols (302+)
  • Internal memory, PC connectivity and optional portable printer

Data management

With the added benefit of an internal memory function, test results can be printed immediately or saved for future processing using the supplied Amplisuite software. The tympanometer also offers single-click integration to third-party Electronic Medical Record (EMR) systems such as NOAH, Auditbase, and OtoAccess®. This enables the seamless transfer of results and data for exceptional workflow efficiency.

  • Extended functionality

    The Otowave 302 includes the perfect array of tests to identify the most common middle-ear pathologies, including 226Hz tympanometry, ipsilateral and contralateral reflex testing. 

    The Otowave 302+ features extensive functionality which can be user-defined:

    • Probe tone impedance measurements at 226Hz and 1000Hz (scalar, vector, and component measurements; admittance (Y), susceptance (B), and conductance (G))
    • Range of ipsilateral and contralateral reflex test measurements at 500Hz, 1kHz, 2kHz and 4kHz
    • Six configurable test profiles designed to standardise sessions and reduce test times


    There are three profiles for adults, children, and neonates, plus three additional customisable profiles based on user requirements.
