1. A system for use by first and second human beings as bed partners lying in a bed for attenuating noise emanating from the airway of the first human being which can be sensed by the auditory nerves of the second human being, the second human being having a head with first and second ears comprising a modeling noise source, first electromechanical means positioned in a first sound region for sensing involuntary snoring noise emanating from the airway of the first human being for creating a first electrical signal having a frequency and amplitude corresponding to the snoring noise sensed in the first sound region, first electrical means for processing the first electrical signal to create a second electrical signal having the same frequency and opposite phase of the first electrical signal and second electromechanical means including first and second speakers in the vicinity of each of the ears of the second human being for converting the second electrical signal to anti-snoring noise for attenuation of the involuntary snoring noise emanating from the airway of the first human being and present in the vicinity of the ears of the second human being, third electromechanical means mounted on the head of the second human being and including a first error microphone located near the first ear and a second error microphone located near the second ear of the second human being for detecting any noise above a predetermined noise level in the vicinity of the first and second ears of the second human being to provide first and second error correction signals and means responsive to the first and second error correction signals to modify the second electrical signal to bring the involuntary snoring noise in the vicinity of the first and second ears of the second human being so that the involuntary snoring noise is below the predetermined noise level, said first electrical means including modeling means using the source of modeling noise for learning the four acoustical transfer of functions versus frequency between the first and second error microphones and the first and second speakers and producing modeling outputs and noise cancellation means utilizing the modeling outputs to generate anti-noise in the first and second speakers.
