Abstract

Methods, apparatus, and articles of manufacture for reducing spillover in a media monitoring system are disclosed. An example method includes identifying media associated with media monitoring data. The media monitoring data is received from a first meter associated with a first media presentation device. The example method includes identifying an expected sound pressure level associated with the first meter. The example method includes comparing the expected sound pressure level to an actual sound pressure level collected from the media by the first meter to determine if spillover occurred. The example method includes crediting the media as a media exposure if spillover did not occur.

Claims

1. A method to reduce spillover in a media measuring system, comprising:

identifying media associated with media monitoring data, the media monitoring data being received from a first meter associated with a first media presentation device;

identifying an expected sound pressure level associated with the first meter;

comparing the expected sound pressure level to an actual sound pressure level collected from the media by the first meter to determine if spillover occurred; and

crediting the media as a media exposure if spillover did not occur.

2. The method of claim 1, wherein a value of the expected sound pressure level depends on a time the media was presented at the first media presentation device.

3. The method of claim 1, wherein the actual sound pressure level is calculated by taking a logarithmic measure of a root mean square sound pressure of an audio signal associated with the media relative to a reference sound pressure.

4. The method of claim 1, wherein comparing the expected sound pressure level to the actual sound pressure level comprises comparing a difference between the expected sound pressure level and the actual sound pressure level to a threshold.

5. The method of claim 1, wherein crediting the media as the media exposure includes marking the media monitoring data as credited.

6. The method of claim 5, further comprising transmitting the marked media monitoring data to a central facility.

7. The method of claim 1, further comprising not crediting the media as a media exposure if spillover did occur.

8. The method of claim 1, further comprising, if spillover did occur, discarding the media monitoring data associated with the spillover.

9. The method of claim 1, further comprising, if spillover did occur, marking the media monitoring data associated with the spillover as not credited.

10. A spillover manager to reduce spillover in a media measuring system, comprising:

a sound pressure level comparator to;

identify an expected sound pressure level for media associated with media monitoring data received from a meter associated with a media presentation device; and

compare the expected sound pressure level to an actual sound pressure level to determine if spillover occurred, the actual sound pressure level based on the media detected by the meter; and

a media creditor to;

credit the media with an exposure if spillover did not occur; and

not credit the media with the exposure if spillover did occur.

11. The spillover manager of claim 10, wherein the expected sound pressure level depends on a time the media was presented at the first media presentation device.

12. The spillover manager of claim 10, wherein the meter is to calculate the actual sound pressure level by taking a logarithmic measure of a root mean square sound pressure of an audio signal associated with the media relative to a reference sound pressure.

13. The spillover manager of claim 10, wherein the sound pressure level comparator is to compare the expected sound pressure level to the actual sound pressure level by comparing a difference between the expected sound pressure level and the actual sound pressure level to a threshold.

14. The spillover manager of claim 10, wherein to credit the media with the exposure, the media creditor is to mark the media monitoring data as credited.

15. The spillover manager of claim 14, further comprising a transmitter to transmit the marked media monitoring data to a central facility.

16. The spillover manager of claim 10, wherein the media creditor is to discard the media monitoring data if spillover did occur.

17. The spillover manager of claim 10, wherein the media creditor is to mark the media monitoring data as not credited if spillover did occur.

18. A tangible computer readable storage medium comprising instructions that, when executed, cause a computing device to at least:

identify media associated with media monitoring data, the media monitoring data being received from a first meter associated with a first media presentation device;

identify an expected sound pressure level associated with the first meter;

compare the expected sound pressure level to an actual sound pressure level collected from the media by the first meter to determine if spillover occurred; and

credit the media as a media exposure if spillover did not occur.

19. The computer readable medium of claim 18, wherein a value of the expected sound pressure level depends on a time the media was presented at the first media presentation device.

20. The computer readable medium of claim 18, wherein the actual sound pressure level is calculated by taking a logarithmic measure of a root mean square sound pressure of an audio signal associated with the media relative to a reference sound pressure.

21. The computer readable medium of claim 18, wherein comparing the expected sound pressure level to the actual sound pressure level comprises comparing a difference between the expected sound pressure level and the actual sound pressure level to a threshold.

22. The computer readable medium of claim 18, wherein crediting the media as the media exposure includes marking the media monitoring data as credited.

23. The computer readable medium of claim 22, further comprising instructions that cause the computing device to transmit the marked media monitoring data to a central facility.

24. The computer readable medium of claim 18, further comprising not crediting the media as a media exposure if spillover did occur.

25. The computer readable medium of claim 18, further comprising instructions that cause the computing device to discard the media monitoring data if spillover did occur.

26. The computer readable medium of claim 18, further comprising instructions that cause the computing device to mark the media monitoring data as not credited if spillover did occur.
