Sennheiser ActiveGuard ear protection

During the course of a day, headset users may be exposed to hazardous incoming noises that can be dangerous to the hearing. The sudden high-pitched signal of an alarm sounding at the other end of the line, for example, can be more than frightening – it can actually cause irreversible damage and pain.

Technically referred to as an acoustic burst, a sudden and unexpected variation in sound level can potentially cause long-lasting damage to the human ear. And this can lead to acoustic shock, which can cause symptoms such as headaches, tinnitus, and even loss of hearing.

To safeguard users from these imminent dangers, all Sennheiser telecom headsets are equipped with the new, innovative ActiveGard™ technology.

This built-in, unique technology safely compresses potentially dangerous sound levels, whereas traditional systems simply clip off high noise peaks. ActiveGard™ allows headset wearers to work more 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 in your headset 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 and 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.
