Nacre’s QUIETPRO+ Intelligent Hearing System

Nacre is the designer and manufacturer of the in-service and proven QUIETPRO+.

QUIETPRO+ is a fully automated hearing and communication system, which enhances soldier’s hearing when needed and protects against temporary and permanent damage. It has been designed specifically to protect the soldier against the full range of battlefield noise in the mounted and dismounted role.

Noise Problem: Mounted and Dismounted

Exposure to high noise levels has long been recognised as an issue for infantry forces.  The two types of noise, high steady (continuous) noise generated by vehicles or aircraft and high impulse noise generated by weapons or explosions are equally damaging in different ways.  Soldiers who are exposed to these types of noise without adequate protection will suffer either temporary or permanent damage.  Hearing damage is accumulative and irreversible.

The operational problems associated with exposure to noise include; increased levels of fatigue, lack of situation awareness and a break down in command and control due to the inability to send and receive intelligible radio communications. At all stages of tactical deployment a high level of communication clarity is vital.

Reducing the level of exposure to the constantly changing noise environment is the key challenge in providing protection and improving communications intelligibility. Across the operational deployment in or out of mobility platforms, the soldier is subjected to different noise types and at different levels; both continuous and impulsive noise.

The QUIETPRO+

QUIETPRO+ is the only tactical communication ancillary system that provides automatic hearing protection throughout the full spectrum of deployed operations; from the moment the operator leaves the operating base to their return. Hearing protection is ensured while the user is inserted or extracted on a range of mobility platforms; AFVs, LAVs, Tactical Wheeled Vehicles, watercraft / riverine platforms and fixed / rotary wing aircraft. This protection continues during the platform dismount and during the dismounted deployment.

The QUIETPRO+ uses digital Active Noise Reduction (ANR) that is effective at combating noise generated by the full range of mobility platforms. The protection continues when the solider dismounts through the use of both passive and active technologies. In many dismounted tactical scenarios there is a high level of steady (continuous) noise that can only be effectively combated using these electronic cancellation technologies.  The adaptive nature of the QUIETPRO+ digital ANR adjusts to the specific characteristic of the individual ear canal, ensuring that the digital ANR system remains highly stable and highly effective.

Harmful high level impulse noises are isolated from the user through the use of advanced digital signal processing. The QUIETPRO+ filters the harmful frequencies, instantly stopping them from reaching the users ears. Full natural hearing (situational awareness) is restored as soon as the harmful noise is no longer present.

QUIETPRO+ employs an ‘in-the-ear’ headset; the lightweight and extremely ruggedized ear piece fits within the concha of the ear and does not obstruct the pinna. The pinna plays an important role in helping determine direction (localisation) of sounds in the users’ immediate surroundings. The stereo headset ensures that a high resolution of directionality is achieved.

Proven

Since QUIETPRO+ entered operational service; more than 50,000 units have been fielded across 13 countries. More than 40,000 of these are in daily service with the US Army, US Marine Corps, US Air Force and US Government Agencies.

Following extensive comparative testing and evaluation the US Army has chosen to add the Nacre QUIETPRO^® to the Army's Approved Product List PM C&IE as the only approved in-ear hearing protection device.
