The
Safety
Principle.
Air Traffic Control Headsets with ActiveGard™
The International Air Traffic Control network, which includes each individual National Air Traffic Service Provider (ATSP), forms one of the most reliable, hence most successful, organizations in the world. The people who are the core of this successful system are the highly trained specialists on duty in Airport Towers and Air Traffic Control (ATC) Centers everyday, making flight safety something that can nearly be taken for granted. Sennheiser supports the performance of these professionals with state-of-the-art communication technology that is constantly developed further by the engineers in our research labs. Our new generation of ATC headsets are lighter than ever and offer a comfortable fit even after long hours of operation. Our innovative ActiveGard™ circuit protects the air traffic controllers' ears from stressful noise peaks. To provide the best audio experience so you can concentrate on your task.
You‘re in Control Sennheiser Aviation. Since the mid-1980s, Sennheiser has helped to ensure clear communication in both the cockpit and in air traffic control. Innovations such as the NoiseGard™ active noise compensation circuitry and the new ActiveGard™ peak protection circuitry have secured a sustaining market demand for Sennheiser’s high quality headsets. Our latest product
generation is optimized to meet the needs of air traffic control operators worldwide, featuring exceptional acoustic performance, wearing comfort and endurance. Safety and reliability are the primary requirements in all aspects of air traffic control. These requirements are fully satisfied by Sennheiser headsets.

ATC HEADSETS WITH ACTIVEGARD™ 02 03
Free to concentrate. Sennheiser’s new, innovative ATC headsets feature an active electronic system to protect you from disruptive or even harmful acoustic signals before they can distract you – for unimpaired maximum communication and physical wellness.
ActiveGard™.
Sudden, loud disruptive signals can occur anytime in voice radio traffic. Not only can they disturb communication in decisive moments, they also pose physical dangers to the operator’s hearing. This problem has been solved with the ActiveGard™ technology developed by Sennheiser. This patented protection system automatically attenuates any noise peaks once they transcend the sensitive mark of 105 dB – before they can reach the ear and affect the operator.
Required by EC directive.
As long as operators continuously use headsets without ActiveGard™, 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 from acoustic stress.
Required by FAA – Hearing and Noise in Aviation. The Federal Aviation
Administration (FAA) also requires using hearing protection for pilots and controllers if the noise level is reaching certain limits.
Created by Sennheiser. ActiveGard™ delivers acoustic protection as prescribed, clearly surpassing conventional solutions. Other systems only cut volume peaks, rendering the signal still very loud and uncomfortably distorted. In contrast, ActiveGard™ actively compresses the entire sound signal and removes the harmful energy. As soon as the volume returns to acceptable levels, the system switches back into monitoring mode.
ATC HEADSETS WITH ACTIVEGARD™ 04 05
For flexible communication. The headsets in the 46 series are excellent for all air traffic control communication applications. The headsets can be operated in 2-channel mode, making it possible to use one channel for control communication with the airplane and the second channel for land telephone connections. Both models in this series feature an open headphone design, are lightweight, deliver first-class comfort and offer the best options for personal adjustments. They have been optimized with one goal in mind: to ensure operator use without fatigue, even over many hours and in changing situations.
Two-piece headband for comfortable, secure fit without pressure points
Noise-compensating condenser microphone ensures excellent speech transmission
Soft ear pads and the patented, automatic opening frame provide for perfect, secure fit – the result of Sennheiser‘s more than 30 years of experience in the aviation headset field. The HME 46-3 features a noise-compensating condenser microphone, which makes speech more natural sounding in every respect.
HME 46-3 / HMD 46-3
The HMD 46-3 variant offers a dynamic microphone with a cardioid pattern to guarantee a high level of intelligibility even in noisy environments; for instance, in a tower during high traffic volume.
