Methods and apparatus to detect spillover
First Claim
1. An apparatus comprising:
- a reverberation analyzer to;
identify a quantity of short durations of loudness in an audio signal of media presented by a media presentation device;
calculate a ratio of the quantity of the short durations of loudness to a quantity of durations of loudness in the audio signal of the media, the quantity of the durations of loudness including the quantity of short durations of loudness;
a processor; and
a memory in circuit with the processor, the memory including instructions that, when executed by the processor, cause the processor to;
store data denoting the media as un-usable to credit a media exposure based on the audio signal being spillover when the ratio does not satisfy a loudness ratio threshold.

Abstract
Methods and apparatus to improve the accuracy of crediting media exposure through detecting reverberation indicative of spillover are disclosed. An example apparatus includes a reverberation analyzer to identify a quantity of short durations of loudness in an audio signal of media presented by a media presentation device and calculate a ratio of the quantity of the short durations of loudness to a quantity of durations of loudness in the audio signal of the media, the quantity of the durations of loudness including the quantity of short durations of loudness. The example apparatus also includes a processor and memory in circuit with the processor, the memory including instructions that, when executed by the processor, cause the processor to mark the media as un-usable to credit a media exposure when the ratio does not satisfy a loudness ratio threshold.

8. An apparatus comprising:
-
means for identifying a quantity of short durations of loudness in an audio signal of media presented by a media presentation device; means for calculating a ratio of the quantity of the short durations of loudness to a quantity of durations of loudness in the audio signal of the media, the quantity of the durations of loudness including the quantity of short durations of loudness; and means for detecting the audio signal as being spillover, the means for detecting the audio signal as being spillover to store data denoting the media as un-usable to credit a media exposure when the ratio does not satisfy a loudness ratio threshold, the storing of the data to improve an accuracy of the media exposure credit by excluding media having indications of spillover. - View Dependent Claims (9, 10, 11, 12, 13, 14)
