The natural listening experience
For the best possible communication
between the Air Traffic controller and the
Pilot Cockpit, EPOS VoiceTM technology,
uniquely enhances the most important
frequencies and details of the human voice.
The sound for the Air Traffic controller iscrisper and clearer, allowing them to hear thenuances contained in spoken conversation.
For the pilot in the cockpit, the Air Traffic

Hearing protection
Contoller using a COMMMAND headset
with noise-cancelling microphone, hears
the clearest voice signal, which maximizes
speech intelligibility and significantly reduces“Call Back-Read Backs”. In combination,
this results in better, more natural sounding
communications where no important details
are lost and this adds to the safety factor.

During the course of a day, Air Traffic
Controllers may be exposed to seldom, buthazardous incoming noises that can be
dangerous to hearing. Technically referred toas a sound burst, this can potentially cause
long-lasting damage to the human ear. To
safeguard users, all COMMAND headsets for
Air Traffic Control (ATC) are equipped with
innovative EPOS ActiveGardTM technology.
Required by EC directive
As long as ATC operators continuously
use headsets without EPOS ActiveGardTM,

unexpected noise peaks can lead to irreversible
conse­quences, from headaches and tinnitus
problems to acoustic shocks or even total
hearing loss. For that reason, the current
EU directives regarding workplace security
prescribe the protection of employees fromacoustic shock.
Required by FAA
The Federal Aviation Administration (FAA)
also requires using hearing protection forcontrollers if the noise level is reaches
certain limits.
