Abstract: Speech enhancement apparatus and respirator masks including speech enhancement apparatus, as well as methods of enhancing speech transmission for the wearer of a respirator mask are described herein. In one or more embodiments, the speech enhancement apparatus and methods described herein detect acoustic energy within a first frequency range in the clean air envelope of a respirator mask and deliver compensating acoustic energy outside of the clean air envelope using a speaker. The compensating acoustic energy is, in one or more embodiments, delivered in one or more predetermined attenuated frequency ranges that cover less than all of the detected first frequency range. In one or more embodiments, the compensating acoustic energy may be delivered with an attenuated amplitude profile that uniform or that is non-uniform over the one or more attenuated frequency ranges.

Abstract: A headset communication device includes at least one processor configured to transmit, via a dedicated virtual communication channel of a wireless communication protocol, local beacon data to one or more remote headset communication devices within a work environment, to discover a remote headset communication device included in the one or more remote headset communication devices by receiving, via the dedicated virtual communication channel of the wireless communication protocol, remote beacon data that is transmitted by the remote headset communication device, to automatically synchronize, based on the remote beacon data, the headset communication device with the remote headset communication device, and, to transmit, via one or more additional virtual communication channels of the wireless communication protocol, local audio communication data to the one or more remote headset communication devices.

Abstract: A voice-activated encoding method includes determining a voice power parameter based on a frequency domain representation of a voice signal from a voice microphone. The method includes determining an ambient power parameter based on a frequency domain representation of at least one ambient signal from at least one ambient microphone spaced from the voice microphone. The method also includes enabling encoding of an audio signal based on the voice signal in response to comparing the power parameters and a threshold value. A headset including a controller may use the method to determine whether to enable or disable encoding, transmission, or both of an audio signal to another device.

Abstract: A method of retrofitting a hearing protector with an active communication device. The method has steps of providing a hearing protector, providing the active communication device and retaining the active communication device at the hearing protector. Further, a hearing protector is provided having two generally dome-shaped earmuffs, an active communication device comprising a loudspeaker and electronic circuitry which comprises a wireless communication interface, and wherein the active communication device has a mounting ring that is retained between an outer shell and a cushioning of the earmuff.
