Methods and apparatus to verify presentation of media content

A non-transitory computer readable medium comprising instructions that, when executed, cause a processor to at least:

• compare a first audio signal associated with media selected via a set-top box to a second audio signal from an audio system of a media presentation device, the second audio signal received by a transducer in a media presentation location;
• periodically prevent receipt of the second audio signal by the transducer for a first time period;
• enable the receipt of the second audio signal after the first time period expires;
• output, based on the comparison, a value indicative of whether the media is presented at the media presentation location;
• and
• provide, based on the output, media presentation information associated with the media to a data collection facility, the media presentation information including a timestamp of the media.
