Amplivox Otowave 202 Tympanometer

Description

Amplivox Otowave 202 Tympanometer

The Amplivox Otowave 202 Tympanometer is a portable high frequency device with a comprehensive range of test functions. Test functions include user defined 226Hz probe tone impedance measurements and a user programmable range of both ipsi and contra lateral reflex test measurements at 0.5kHz, 1kHz, 2kHz and 4kHz. The Otowave 202 is the perfect instrument to help audiologists and hearing aid dispensers identify middle ear disorders, but also to differentiate conductive and sensorineural hearing issues in combination with an audiogram.

Acoustic reflex measurements

User-defined ipsi and contra lateral reflex test measurements can be easily added to the test sequence to ensure a comprehensive test routine that is completed in the minimum amount of time. This user programmable acoustic reflex function includes reflex frequency selection, levels and sensitivity. The large display area facilitates a graphical display of the reflex response and a pass/no response result.

Recording results

Based upon user requirements, results can be:

• Saved within the internal memory with a patient identifier
• Printed via optional thermal printer
• Transferred via USB to a PC for viewing and printing using the Amplivox ampliSuite application
• Transferred via USB to the NOAH database using the Amplivox NOAH impedance module
