Abstract:
A hearing protection system is provided. The hearing protection system has a first active hearing protection system. The first active hearing protection system is level-dependent. The hearing protection system also has a second active hearing protection system. The second active hearing protection system is level-dependent. Each of the first and second active hearing protection systems are configured to operate in an independent mode and a dual-protection mode. A dual-protection mode level dependent function of the second active hearing protection system is different than an independent mode level dependent function.
