MH / PRR Headset System

Atlantic Signal was approached by a NATO military organization in 2005 and asked to develop a tactical bone conduction headset for them to replace the over the ear style headset that is included as standard with the Selex Personal Role Radio (PRR). The client had received a number of complaints from soldiers in the field regarding the standard headset including discomfort related to the strapping system, a loss of situational and directional awareness on the ear cup side of the headset and the inability to incorporate any form of electronic or inert hearing protection.

Unlike conventional military hand-held portables, the PRR is a short range tactical radio that operates independently of any RF infrastructure. With only 50 milliwatts of power provided by two disposable AA Alkaline batteries, the PRR radio would not work with our bone conduction headset line.

As a result, we designed, developed and ultimately manufactured the world's first and only tactical bone conduction headset system that operates with the PRR radio and has no reliance or negative impact whatsoever with the AA battery power utilized by the radio.

We developed our own water-tight, power supply housing that holds two disposable AA cells that equal the duty cycle, battery life requirements of the radio (1 hour TX / 7 hours RX / 16 hours standby). The housing is available with a stainless steel, alligator-style clip for affixing to various styles of LBE and MOLLE vest systems. We also offer a MOLLE carrying pouch for the housing as an alternative method of attaching to a vest.

Our PRR interface affords a client the choice from the MH180H, MH180V and MH3 upper headset styles as any of these models will work with the PRR – it’s simply a matter of choice for the client.

Because of mechanical coupling issues associated with traditional boom microphones and bone conduction headsets, we developed a waterproof / noise canceling ‘baffle boom microphone’. This unique microphone features an air baffle between the microphone side bone conductor housing and microphone element to eliminate the phenomenon of mechanical coupling.

By utilizing an MH Series headset on the PRR radio, a client benefits from the advantage of being able to employ hearing protection when he wants while being able to remove it when not desired – all the while having no impact whatsoever on his ability to RX and TX radio communications. Secondly, since the MH Series headsets require no type of hardware in, on or over either ear, the operator has 360 degrees of un-occluded situational and directional awareness. Lastly, the problem of operator’s ear canals filling with sweat experienced by soldiers throughout the NATO community when wearing the standard issue ear cup headsets – is eliminated by switching to any of the MH Series upper headset models.
