A method of communicating using a breathing apparatus includes receiving an audio signal from a sound acquisition unit. The method further includes determining a state of the breathing apparatus based on the received audio signal. The state is at least one of a first state and a second state. The method further includes applying a first filter on the audio signal if the determined state is the first state. The first filter has a first frequency response. The method further includes applying a second filter on the audio signal if the determined state is the second state. The second filter has a second frequency response different from the first frequency response of the first filter. The method further includes generating an output signal based on the application of the first filter or the second filter. The method further includes receiving the output signal at an output device.

Breathing apparatus and method of communicating using breathing apparatus

A respiratory device and system, and in particular a respiratory device that is usable with a plurality of removable electronic function components that that can communicate wirelessly with other devices. In one embodiment, a respiratory device comprises a body, at least a portion of the body defining a volume; a mask communications unit (MCU) at least partially located within the volume; at least one electrical function component in communication with the MCU; and a rechargeable power source at least partially located within the volume, the rechargeable power source providing power to each of the at least one electrical function components.
