General Information

Scale name Exposure / multiple media / politics
Scale description Panelists were offered a web-enabled smart phone. The IMMI phones detect ambient room noise for each panelist on every day. The sounds were encoded, not recorded. By automatically comparing the uploaded audio fingerprints captured by the phones with audio fingerprints stored on the IMMI servers, IMMI identifies all of the media to which each respondent is exposed to.
