The invention relates to a method for measuring audiences using the sound collected by mobile devices carried by people, in order to produce the frequency spectrum thereof, compress same and transmit same to a processing centre. In addition, the frequency spectrum of the sound emitted by multiple radio and television transmitters is collected for the purposes of comparing them and thereby determining the similarities between both sounds, and, in the event that a match is determined, generating a report, and calculating the audience of every electronic medium based on these reports, be it AM radio, FM radio, satellite radio, aerial television, cable television, satellite television, signals transmitted via Internet, telephone, wireless radiofrequency transmissions, transmissions via electrical conductors, light transmissions with or without fibre optics, transmissions via material media using acoustic vibrations, as well as signals recorded in mechanical, magnetic, electrostatic, semiconductor, chemical, biological and graphical printed media. |
