Why is it that a listener on a cell phone cannot hear music on the other end? For example, the source phone is located either in a car with music being played, or is at a concert.
The listener hears some notes, but for the most part the music is garbled and rarely is distinguishable what is being played.
I figured it has something to do with distortion, the size of the pickup mic, or the range of the pickup mic, but don't know.
