Classification: CPC H  A | IPC A  H

Claim 10:
11. The audiometer system of claim 1 wherein:
the transducer further comprises a second audio speaker positioned in communication with the transducer processor unit;
the audiometer DSP unit is further configured to:
generate masking signals responsive to a user input masking signal;
convert the masking signals to a plurality of masking data packets; and
interleave each of the plurality of masking data packets and the plurality of stimulus data packets, defining a plurality of interleaved data packets, wherein each interleaved data packet comprises a header, at least one masking data packets, and at least one stimulus data packets;

the audiometer baseband processing unit is further configured to:
receive the plurality of interleaved data packets from the audiometer DSP unit; and
generate a plurality of interleaved audiometer frames, each frame comprising a packet of the plurality of interleaved data packets; and

the audiometer light-based transceiver is further configured to transmit the interleaved audiometer frames received from the audiometer baseband processing unit;
the transducer further comprising a second audio speaker positioned in communication with the transducer processor unit;
the transducer light-based transceiver is further configured to receive the plurality of interleaved audiometer frames from the audiometer light-based transceiver;
the transducer baseband processing unit is further configured to:
receive the plurality of interleaved audiometer frames from the transducer light-based transceiver; and
extract the plurality of interleaved data packets from the audiometer frames, defining a plurality of extracted interleaved data packets; and

the transducer processor unit is further configured to:
receive the plurality of extracted interleaved data packets from the transducer baseband processing unit;
convert the plurality of extracted interleaved data packets into a masking audio signal and the patient stimulus signal; and

the second audio speaker is configured to:
receive the masking audio signal from the transducer processor unit; and
generate a masking sound responsive to the masking audio signal.
