New Testing Options with the TympStar Pro

Multi-Frequency Test

The addition of the Multi-Hz test to the TympStar Pro provides audiologists the tools needed to confidently identify resonance frequency of the middle ear system. This powerful test can be completed five times faster than its predecessor and takes as little as 13 seconds to complete. Multi-Hz offers the efficiency and accuracy needed to assess pathologies in the middle ear system.

Patulous ET Identification

The TympStar Pro now has a dedicated test type to identify a patulous Eustachian tube. The capability to store measurements from four test conditions and an adjustable time base makes the Patulous ET test a reliable, flexible, and customizable option to meet the need of every facility’s protocol.
