Claim 12:
13. An audiometer system comprising:
an audiometer device comprising:
an audiometer digital signal processing (DSP) unit configured to:
receive at least one of an input audio signal and an input speech signal, defining an input signal;
generate a stimulus stream responsive to the input signal; and
generate a plurality of packets from the stimulus stream, defining stimulus data packets;

an audiometer baseband processing unit positioned in communication with the audiometer DSP unit and configured to:
receive the stimulus data packets from the audiometer DSP unit; and
generate a plurality of stimulus audiometer frames, each frame comprising a packet of the stimulus data packets; and

an audiometer light-based transceiver positioned in communication with the audiometer baseband processing unit and configured to transmit the plurality of stimulus audiometer frames;

a transducer comprising:
a transducer light-based transceiver positionable within a field of view of the audiometer light-based transceiver, the transducer light-based transceiver configured to receive the plurality of stimulus audiometer frames from the audiometer light-based transceiver;
a transducer baseband processing unit positioned in communication with the transducer light-based transceiver and configured to:
receive the plurality of stimulus audiometer frames from the transducer light-based transceiver; and
extract the stimulus data packets from the stimulus audiometer frames, defining extracted stimulus data packets;

a transducer processor unit positioned in communication with the transducer baseband processing unit and configured to convert the plurality of extracted stimulus data packets into a patient stimulus signal;
an audio speaker positioned in communication with the transducer processor unit and configured to generate a sound responsive to the patient stimulus signal; and
a transducer input device positioned in communication with the transducer processor unit and configured to:
receive a patient input from the patient, defining a received patient input; and
generate a patient response signal from the received patient input;

wherein the transducer processor unit is further configured to convert the patient response signal to a plurality of transducer data packets;
wherein the transducer baseband processing unit is further configured to generate a plurality of transducer frames, each transducer frame comprising a transducer data packet;
wherein the transducer light-based transceiver is further configured to transmit the plurality of transducer frames to the audiometer light-based transceiver;
wherein the audiometer light-based transceiver is further configured to receive the plurality of transducer frames from the transducer light-based transceiver;
wherein the audiometer baseband processing unit is further configured to convert the plurality of transducer frames to a received patient response data packet; and
wherein the audiometer DSP unit is further configured to:
convert the received patient response data packet to an audio signal, defining a received patient audio signal; and
transmit the received patient audio signal to a user playback device.
