EARS (Electroacoustic Auto Response System) has been designed to provide a quick and convenient way of checking the performance of an audiometer, and features a unique response button testing facility.

This electroacoustic ear provides accurate and consistent responses to tones and gives thresholds over the frequency range 500Hz – 8000Hz.

What can EARS offer you?

EARS provides you with the ability to quickly confirm that the sound output of your audiometer, as delivered to the earphones or through booth connections, is as expected. It also has a unique response button testing facility.

Why check your audiometer with an electroacoustic ear?

Checking performance prior to use is recommended by the Health & Safety Executive in their publication ‘Controlling Noise at Work’, in order to pick up degradation in booth sockets, cables, audiometer earphones and audiometer performance. EARS is the ideal choice for performing this check as it consistently provides accurate thresholds.
