## What is Acoustic Leakage Tester?

The Acoustic Leakage Tester App is the integral part of the Acoustic Leakage Tester (ALT).

Designed for use by Audiologists, custom earpiece manufacturers and anyone supplying hearing protection solutions, the ALT from DEC is a portable, easy to use leakage test system for use with both custom and universal earpieces. The ALT app runs on any iDevice having a lightning connector and works solely together with Dynamic ear Company's Acoustic Sensor Unit and Calibration Unit. 

ALT provides single button measurement and automated calibration routine, ensuring accurate results every time. Comfort and correct fitting are paramount for the client; being an acoustic system DEC’s ALT eradicates pain and misfitting due to over and under pressurisation. Continuous measurements allow for verifying the correct fit in different jaw-bone positions. E.g. for vocal musicians with mouth closed and open.

Health and Safety departments wishing to train employees on the correct fitting and insertion of universal fit hearing protection can use ALT.
