Abstract:
1. A method comprising: generating, by a remote control subsystem, an audio control signal that comprises a first pilot audio tone having a first audio frequency and a second pilot audio tone having a second audio frequency, the first and second pilot audio tones configured to indicate a time to start sampling data representative of one or more control parameters included in the audio control signal; acoustically transmitting, by the remote control subsystem, the audio control signal to a sound processing subsystem communicatively coupled to a stimulation subsystem implanted within a patient; detecting, by the sound processing subsystem, the first and second pilot audio tones included in the audio control signal; starting to sample, by the sound processing subsystem, the data included in the audio control signal at the time indicated by the first and second pilot audio tones; extracting, by the sound processing subsystem, the data representative of the one or more control parameters from the audio control signal while sampling the data included in the audio control signal; and performing, by the sound processing subsystem, at least one operation in accordance with the data representative of the one or more control parameters extracted from the audio control signal.
