When hearing the same sound coming out from a Radio and a TV simultaneously (e.g., when a channel is beeing broadcasted on the radio and on TV at the same time), the radio sound precedes the sound coming out of the TV. The phenomenon is quite noticeable. The reason for this must be technological, and is likely due to different delay time/s through both machineries. I'd like to get more information about this delay and related phenomenon. Thanks.
