HEARLINK has launched a two-way communication and hearing protection device.
The device comprises a custom made earpiece with a built in high profile miniature microphone and speaker.
All the electronic parts are embedded in the earpiece, insulating against environmental noise.
The device is connected via a Push To Talk (PTT) interface.
The PTT interface has all the electronics for signal conditioning and gives the command for transmit and receive mode.
When a call comes in, the user will hear the message directly in the ear.
When talk back is required, a push on the PTT switch will activate the microphone inside the earpiece, which picks up the vibrations from the voice in the ear canal and sends it via the radio to the receiving destination.
