Sonic SPEAKTHRU' easy communicator

Sonic SPEAKTHRU' easy communicator

The SONIC SPEAKTHRU’ is independent of any mechanical sound amplification device, yet enables counter staff working behind protective glass screening, to speak with customers at a normal, conversational speech level.

This is uniquely achieved by means of a micro-thin inner membrane which allows sound transmission, but which stops draughts and germs – this helps to maintain a healthy working environment with minimal absenteeism through sickness.
