The unique, built-in, G616 compliant ActiveGard™ technology from Sennheiser, safely compresses potentially dangerous sound levels. Whereas, traditional systems simply clip high noise peaks.
All Sennheiser SH and CC series headsets have ActiveGard™ technology, enabling wearers to work, relaxed in the knowledge that their headsets are equipped with this outstanding technology to help ensure their safety.
Before an undesirable incoming signal even reaches your ears, the ActiveGard™ technology acts as an automatic control to instantly lower the volume of unacceptably loud, high, or deep sounds.
Using sophisticated electrical circuits; the energy of the acoustic burst is actually removed, not just reduced. At the same time, the sound itself is compressed without distorting it. When the volume reaches acceptable standards again, it is allowed to return to the original, comfortable level. The automatic guard then returns to surveillance mode.
All headsets from Sennheiser Communications are delivered with their unique, highly advanced ActiveGard™ technology. This technology has been tested and complies with "ACIF G616:2006 Acoustic safety for telephone equipment". The patented system utilizes compression technologies to remove the energy from an excessive incoming signal transmitted through the telephone system and leaves the signal free of distortion.
