Sennheiser Activegard

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 Communications telecom headsets are equipped with the new, innovative ActiveGard technology.
