1. A mobile radio, comprising:
a communication interface configured to:
receive at least one of first wireless audio signals from a wearable mask and second wireless audio signals from another mobile radio; and
processing circuitry in operative communication with the communication interface, the processing circuitry configured to, if first wireless audio and second wireless audio signals are received by the communication interface, sum the first and second wireless audio signals for transmission to a remote speaker microphone if a first criterion is met, wherein the first criterion corresponds to at least one of whether the second wireless audio signals have a higher priority than the first wireless audio signals and whether a push to talk (PTT) button has been activated.
