METHODS AND SYSTEMS FOR REDUCING SPILLOVER BY MEASURING A CREST FACTOR

摘要

Methods, apparatus, and articles of manufacture for reducing spillover in a media monitoring system are disclosed. An example method includes comparing a first crest factor stored in association with a media identifier to a second crest factor calculated by a first meter, the second crest factor corresponding to a ratio of a peak amplitude of an audio signal and a root mean square value of the audio signal. The example method also includes determining that spillover did not occur if a difference between the first crest factor and the second crest factor satisfies a threshold, and when the spillover did not occur, crediting a media exposure to media associated with the audio signal.
