Claim:
1. A process for providing active noise cancellation and biofeedback in an electronic pillow comprising a pillow unit operatively coupled to a reference sensing unit and a controller unit, the process comprising: receiving signals via a plurality of error microphones encased in the pillow unit, wherein the error microphones are spaced a first predetermined distance from one another; receiving at least one signal from at least one reference sensing microphone in the reference sensing unit; and processing signals received from the error microphones and reference sensing microphone in the controller unit to simultaneously reduce noise and provide biofeedback in an area between the error microphones using a plurality of speakers encased in the pillow unit, wherein each of the speakers are spaced a second predetermined distance from each of the respective error microphones, wherein noise is reduced in the controller unit utilizing a multiple-channel feed-forward active noise control, and wherein the controller unit processes signals received from the at least one of the error microphones and the controller unit simultaneously provides both acoustic echo cancellation and biofeedback, wherein the biofeedback comprises emitting a sound at frequencies of less than 2.0 Hz by using constructive and/or destructive interference patterns of higher frequency sound waves or volume modulation of source content from at least one of the plurality of speakers.
