A microphone receives a wireless communication including a command that contains two or more redundant instances of a data packet, each instance contains a same command. Each redundant data packet is sent on its own carrier frequency in an audio frequency band. A configurable filter engine passes a signal corresponding to the same command transmitted by the audio frequency speaker built into that external computing device through one or more audio band band-pass filters. A control processor examines the band-passed signal and extracts information to extract the content payload of the data packet. A signal processor carries out an operation corresponding to the command from the content payload of the data packet in the hearing assistance device.
