1. An apparatus comprising:
media identification circuitry to generate first audio signatures representative of first audio data associated with a monitored media device;
a comparator to:
obtain second audio signatures from a portable meter, the second audio signatures generated by the portable meter based on second audio data sensed by a sensor of the portable meter, the second audio signatures to be representative of the second audio data sensed by the portable meter; and
compare the first audio signatures and the second audio signatures to determine a comparison result;
presence detection circuitry to determine a presence status of a user based on the comparison result, the user associated with the portable meter; and
network communication circuitry to:
transmit a prompt to the portable meter to cause the sensor of the portable meter to sense the second audio data; and
transmit the presence status to a data processor to perform audience measurement based on the presence status.
