Claim Text:
1. A method to classify audio, the method comprising: associating, by executing an instruction with a processor, blocks of audio sensed from a media presentation device with volume events, a first audio block being associated with a first volume event when (1) the first audio block has a first volume value satisfying a volume threshold and (2) a ratio of the first volume value and a second volume value of a second audio block associated with a second volume event satisfies an event threshold; determining, by executing an instruction with the processor, a first count of volume events having respective elapsed times corresponding to a first range, a respective elapsed time of the first volume event corresponding to a first period of time between the first audio block and the second audio block; determining, by executing an instruction with the processor, a second count of volume events having respective elapsed times corresponding to a second range; and classifying, by executing an instruction with the processor, the audio sensed from the media presentation device based on the first count of volume and the second count of volume.
