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 crest factor associated with the media. The example method includes comparing the expected crest factor to a received crest factor to determine if spillover occurred. The received crest factor is received from the first meter. The example method includes crediting the media as a media exposure if spillover did not occur.
