Abstract
Apparatus and methods for creating a sensation in which a sound driver emits sound waves according to incoming information, and one or more light emitters emit light waves with varying patterns according to amplitude and frequency changes in the incoming information. Preferably, only low frequency signals (below 50 Hz) are used to produce the pattern of the light waves, which are directed directly towards the tympanic membrane without any artificial barrier. Emitted light preferably reaches the inner ear region substantially simultaneously with emitted sound waves. A second light emitter can be used to emit light waves that are complementary to, and preferably between 175 and 185 degrees out of phase with, the light waves from the first light emitter, to produce scalar waves.
