Claim 10:
11. The voice cancellation system of claim 10, wherein the first sound decelerator includes at least one first tortuous sound conduit that may be filled with sound retarding materials to increase a traveling time of the voice sound waves from the left side of the sound muffling chamber to the sound silencing chamber;
wherein the second sound decelerator includes at least one second tortuous sound conduit that may be filled with porous sound retarding materials to increase a traveling time of the voice sound waves from the right side of the sound muffling chamber to the sound silencing chamber;
wherein the increase of sound transmission time through each of the first and second decelerators is at least the time required for the signal processing system to process the voice signal and produce the voice cancellation signal in the sound silencing chamber;
wherein the at least first one tortuous sound conduit and the at least second one tortuous sound conduit may each be of spiral, convoluted, zigzag, helical, wavy, or labyrinthine pattern; and
wherein each of the first and second decelerators are enclosed with a soundproof enclosure.
