I intend to do a mini project on noise elimination... such that this circuit can identify a particular voice and cancells other noises.... is this possible... Anybody please help me...
However you can do a simple test with your stereo Radio by simply altering the polarity of the wires of one speaker...
is it really as simple as that to cancel noise? is that what bose does with their head phones (e.i. have a mic picking up noise from outside and having a reverse polarity speaker reflect the negated noise back outside to cancel it)?
