Basics of stereo listening
When listening to speakers sound coming from the right is not only perceived with the right ear (red line) but it is
also perceived with the left ear (green line). The sensation is time delayed, lower in level and has a reduced fre-
quency range (this applies to the left speaker accordingly).
Right loudspeaker
Left loudspeaker
It arrives later because the signal travels a distance of approx. 340 meters per second and the distance from the right speaker to the left ear is
longer than it is to the right ear. It is quieter and does not deliver the full frequency range, because the signal of the right speaker does not directly
arrive at the left ear but is partially reflected and absorbed by the head.
