This test persons carries a portable monitor. Furthermore, the broadcast receiving devices may bear such monitors, a direct electrical connection with the monitor being possible besides the acoustic recording of the hearing samples. The hearing samples are converted into digital form by adequate methods, then compressed and optionally encoded. In greater time intervals, the hearing samples are transmitted to a center where the hearing samples are correlated with program samples taken simultaneously from the monitored programs.
