Abstract
Official abstract text for this publication.
A method and apparatus are provided for gathering research data indicating exposure to audio content to a user of an audio source device and an audio receiver device. The audio source device wirelessly transmits an audio signal containing the audio content. The audio receiver device receives an audio signal containing the audio content. The audio receiver device includes a speaker to output the audio content to be heard by the user. The apparatus includes a bridge device for wirelessly bridging the audio signal from the audio source device to the audio receiver device. The bridge device includes a speaker for outputting the audio content from the audio signal. The apparatus also includes a monitoring device acoustically coupled to the bridge device for monitoring the audio content output by the speaker of the bridge device, and generating research data identifying the audio content.
