Noise controlling process for use in e.g. automobile, involves determining sound waves in surrounding air space, and regulating sound amplitudes following Laplace law for controlling excess sound amplitudes

摘要

The process involves determining sound waves in the surrounding airspace. Amplitudes of sound are regulated following Laplace law for controlling excess sound amplitudes. The controlled sound amplitudes modify an acoustic environment of the surrounding airspace by counter-electromagnetic effects of inductors that are connected with their windings in opposing sense. The inductors are preferably wound with gold-plated copper wire of 1 mm2 cross-section. An independent claim is included for an apparatus for controlling noise.
