Ear-piece provides hearing protection at louder ambient noise levels

Phonak Communications : 10 February, 2010  (New Product)
Teams of police or guards relying on communication through headsets now have access to improved communication systems enabling clear communications with hearing protection in loud environments
Ear-piece provides hearing protection at louder ambient noise levels
Phonak Communications has launched primero DPC, a new in-ear radio headset with built-in intelligent hearing protection that allows professional teams to communicate in louder noise than ever before.

primero DPC is Phonak's breakthrough boomless radio headset with dynamic hearing protection. Designed for use in extreme sound environments, this system raises the bar of safe radio communications by enabling conversation in noise of up to 115dB (approximately 10dB louder than competitors). Further hearing protection is also guaranteed should even louder 'impulse' noises such as shots or crashes occur.
Designed with teams such as rapid intervention, SWAT, police, emergency and homeland security professionals in mind, primero DPC comprises two key technologies:

* primero in-ear voice pick-up headset

Phonak's primero uses a tiny microphone (situated within the earJack) and an innovative signal processing algorithm to pick up the user's voice from inside the ear canal. This allows speech signals to be detected more effectively in noise than with equivalent external microphone products. It also ensures that primero is compatible with all helmets and masks.

* DPC (dynamic hearing protection) technology

The earJack slots into Phonak's custom-molded nylon eShells, which sit comfortably in the user's ears. DPC technology, via the earJacks, measures the surrounding noise and adapts primero DPC's attenuation (sound dampening) accordingly. In quiet situations this means the primero DPC user retains full ambient awareness; however when noise levels increase above safe levels (85 dB) the user's hearing is fully protected.

"The arrival of primero DPC smashes the traditional 105 dB noise barrier for teams of radio users, allowing professionals to hold clear and understandable conversations in the very loudest noise without having to worry about the dangers of hearing loss," says Evert Dijkstra, Managing Director of Phonak Communications.

primero DPC connects to all professional portable radios and is available with wired and wireless PTT units.
