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 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.

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, in one or more embodiments, exhibits a predetermined attenuated amplitude profile such that the compensating acoustic energy has an amplitude less than 6 dB greater than the acoustic attenuation profile of the mask body over at least 90% of a predetermined attenuated frequency range.
