Abstract

The present invention relates to a method and equipment for conducting a survey among the listeners of radio stations. The method comprises measuring the total amounts of listeners of radio stations by observing the leakage radiation signals of the local oscillators of the radio receivers of the vehicles passing the measuring point, this observation being carried out essentially simultaneously at several predetermined frequencies, which are dependent on the frequencies of the radio stations that one wants to observe. In the calculation of the numbers of listeners, the measurement result of the number of listeners of each radio station is increased when the frequency of the leakage radiation signal of the local oscillator of the radio receiver of a vehicle passing the measuring point includes the information that the radio receiver of said vehicle was tuned into the frequency of said radio station.
