  • Method and arrangement for controlling acoustical output of earphones in response to rotation of listener's head
    Patent number: 3962543
    Abstract: Sound signals are created at the eardrums of a listener to correspond to sound signals which would be created at the eardrums of the listener in a predetermined acoustical environment in response to first electrical signals applied to a loudspeaker having known sound-reproducing characteristics. A determination of the relative position of the head of the listener when the listener is in the predetermined acoustical environment is made, producing a second signal. An equalizing network is provided with a first input for receiving said first electrical signals, and a second input for receiving the second signals, and a pair of outputs connected to the earphones on the headset of a listener.
