Communication Earplug Protection (CEP) Kits

For Helmets and Headsets

Overview:

CEP Kits provide excellent hearing protection for helmets and headsets. They are great alternatives to ANR systems, battlefield-hardened, require no batteries, very easy to install, and will fit any helmet and most standard size headsets. CEP Kits can also be added to ANR headsets and helmets systems for the ultimate in noise protection.

The Communication Earplug Protection Kit was developed by the US Army Aeromedical Research Laboratory (USAARL) at Fort Rucker, Alabama, for use in helicopter helmets.

Tests conducted by USAARL with aviation units in the field, fully demonstrated the capabilities of the CEP. These tests showed significant reductions in noise frequency spectra that are prevalent in helicopters. In addition, speech intelligibility was rated higher with the CEP system than with any other noise protection system, including active noise attenuation systems. As a result of these extensive tests, the US Army chose the CEP system as the only ancillary noise protection device for use in helicopter helmets for US Army Aviators.

How they work:

The CEP system provides exceptional hearing protection by using small transducers (speakers) attached to expanding foam earplugs. This system passes the clearest speech signal attainable directly to the ear, provide extremely high speech intelligibility, even in the noisiest environments.

The CEP consists of a pair of miniature speakers or transducer elements to provide monaural signals to each ear. Expandable foam earplug tips are attached to these elements to provide a noise barrier, while incorporating a aural tube through the earplug tip to transmit the desired communications. The elements are connected to small wires which are plugged into the CEP headset/helmet adapter.
