2. The method as described in claim 1 , wherein storing the first identifier associated with the first audio and the identification code associated with the second meter if the first identifier and the second identifier substantially match is performed at the first meter.
3. The method as described in claim 2 , further comprising transmitting the first identifier associated with the first audio and the identification code associated with the second meter from the first meter to an audience measurement data center.
4. The method as described in claim 1 , further comprising:
transmitting the first identifier associated with the first audio, the identification code, and the at least one of the second audio and the second identifier associated with the second audio from the first meter to an audience measurement data center; and
wherein storing the first identifier associated with the first audio and the identification code associated with the second meter if the first identifier and the second identifier substantially match is performed at the audience measurement data center.
5. The method defined in claim 1 , wherein the first meter and second meter are communicatively coupled by a wireless connection.
6. The method defined in claim 1 , wherein the second meter computes a gain level for the second audio.
7. The method defined in claim 6 , wherein the gain level for the second audio is transmitted to the first meter and is used to determine if the first identifier and the second identifier sufficiently match.
8. The method defined in claim 1 , further comprising:
receiving a movement signal indicative of movement of the second meter at the time of receiving the second audio at the first meter; and
wherein storing the first identifier associated with the first audio and the identification code associated with the second meter if the first identifier and the second identifier substantially match is performed when the movement signal indicates movement at the time of receiving the second audio at the first meter.
9. The method as defined in claim 1 , wherein deriving a first identifier associated with the first audio and receiving an identification code and at least one of a second audio and a second identifier associated with the second audio from a second meter are performed at an audience measurement data center.
10. The method as defined in claim 9 , wherein storing the first identifier associated with the first audio and the identification code associated with the second meter if the first identifier and the second identifier substantially match is performed at the audience measurement data center.
11. The method as described in claim 1 , wherein the first meter is a mailable meter.
12. The method as described in claim 1 , wherein the second meter is a wearable meter.
13. The method as described in claim 12 , wherein the second meter is a bracelet.
14. The method as described in claim 1 , further comprising transmitting a measurement signal from the first meter to the second meter instructing the second meter to receive the second audio.
15. The method as described in claim 14 , wherein the measurement signal further instructs the second meter to derive the second identifier associated with the second audio.
16. A system to monitor media exposure comprising:
a first meter to receive first audio, compute a first identifier for the first audio, receive a second identifier from a second meter, and store the first and second identifiers; and
the second meter to receive a second audio, compute the second identifier for the second audio, and transmit the second identifier to the first meter, the second meter to transmit an identification code uniquely associated with the second meter to the first meter, the first meter to, if the first identifier and the second identifier substantially match, store (A) at least one of the first identifier and the second identifier, and (B) the identification code.
17. The system as described in claim 16 , wherein the first meter is further to compare the first and second identifiers to determine if the same audio was received by both the first meter and the second meter, and store audience measurement data comprising a timestamp and the at least one of the first identifier and the second identifier.
18. The system as described in claim 16 , further comprising an audience measurement data center to:
receive the first and second identifiers from the first meter;
compare the first and second identifiers to determine if the same audio was received by both the first meter and the second meter; and
store audience measurement data comprising a timestamp and at least one of the first and second identifiers.
19. The system as described in claim 18 , wherein receiving the first and second identifiers from the first meter is performed by transporting the first meter to the audience measurement data center.
20. The system as described in claim 18 , wherein receiving the first and second identifiers from the first meter is performed by electronically transmitting the first and second identifiers from the first meter to the audience measurement data center.
21. The system as described in claim 16 , wherein the second meter is to transmit a movement signal indicative of movement of the second meter, the first meter to receive the movement signal and to store the indication of movement of the second meter.
22. The system as described in claim 16 , wherein the first meter is a mailable meter.
23. The system as described in claim 16 , wherein the second meter is a wearable meter.
24. The system as described in claim 17 , further comprising an audience measurement data center to receive the audience measurement data.
25. The system as described in claim 24 , wherein receiving the audience measurement data is performed by transporting the first meter to the audience measurement data center.
26. The system as described in claim 24 , wherein receiving the audience measurement data is performed by electronically transmitting the audience measurement data from the first meter to the audience measurement data center.
27. The system as described in claim 16 , wherein the transmission between the second meter and the first meter is implemented according to an Institute of Electrical and Electronics Engineers 802.15.4 standard.
28. An apparatus to monitor media exposure, the apparatus comprising:
an audio receiver to receive audio;
a data storer to store the received audio in a data store;
a communicator to transmit the audio stored in the data store to a metering device; and
a housing to include the audio receiver, the data storer, the data store, and the communicator, wherein the housing is a gel bracelet.
29. The apparatus as described in claim 28 , wherein the metering device is a mailable meter.
