METHODS AND APPARATUS TO DETECT SPILLOVER

摘要

Methods and apparatus to improve the accuracy of crediting media exposure through detecting reverberation indicative of spillover. Example disclosed methods involve determining periods of loudness in media presented by a media presentation device, and identifying a quantity of the periods of loudness that satisfy a duration threshold. Disclosed example methods also involve calculating a ratio by dividing the quantity of the periods of loudness that satisfy the duration threshold by a total number of periods of loudness in the media. Disclosed example methods also involve marking the media as usable to credit a media exposure if the ratio satisfies a loud threshold.

1. A method to credit media in a media measuring system, comprising:
determining, by executing an instruction with a processor, periods of loudness in an audio signal of the media presented by a media presentation device; identifying, by executing an instruction with the processor, a quantity of the periods of loudness that satisfy a duration threshold; calculating, by executing an instruction with the processor, a ratio of the quantity of the periods of loudness that satisfy the duration threshold and a total number of periods of loudness in the media; and marking, by executing an instruction with the processor, the media as un-usable to credit a media exposure when the ratio does not satisfy a loud threshold, the marking of the media to improve the accuracy of the media exposure credit by excluding media having indications of spillover.
