Abstract
A method for active noise reduction includes sensing one or more characteristics of a sound wave; calculating an inverted sound wave based on the one or more characteristics; and emitting the inverted sound wave by flowing a current, selected according to the inverted sound wave, through a wire under tension that passes through a positive pole of a magnet and a negative pole of the magnet, thereby causing the wire to vibrate. An apparatus for active noise reduction includes a microphone configured to detect one or more characteristics of a sound wave detected in a predetermined vicinity of the microphone; a processor coupled to the microphone, configured to calculate an inverted sound wave based on the one or more characteristics; a power supply; and at least one emitter module coupled to the processor, each emitter module including one or more magnets with a positive pole and a negative pole, a wire, made of a conductive material, under tension, that passes between the positive pole and the negative pole, and the power supply configured to deliver a current passing through the wire, the current selected by the processor to vibrate the wire and thereby emit the inverted sound wave.
