ABSTRACT:
A portable stereo sound set adapted to be worn by a dancer who listens to dance music through left and right earphones mounted on his head and connected to the binaural amplifier channels of the set. Included in each channel is an amplitude-control stage to adjust the base level of sound volume in the related earphone. Attached to each earphone is an attitude-sensitive potentiometer connected to the amplitude control stage on the corresponding channel. The volume of sound in each earphone is caused to deviate from the base level in a direction and to an extent which is a function of the changing resistance of the related potentiomer. The resultant volume of sound heard in each earphone therefore depends on the inclination or tilt of the head of the dancer. Because the dancer's movements are reflected in the changing attitude of his head, the volume of sound, as heard by the dancer through the earphones, is coordinated with his movements, thereby creating a feedback relationship therebetween which enhances the dancing experience.
