METHOD AND APPARATUS FOR ACTIVE NOISE CANCELLATION WITHIN AN ENCLOSED SPACE

摘要

A method of active noise cancellation and an associated system for cancelling noise within an enclosed space are described. The method involves detecting acoustic noise outside of the enclosed space. The method then involves generating a noise cancellation signal outside of the enclosed space, such that the acoustic noise is cancelled prior to the acoustic noise entering the enclosed space.

主权项

1. An active noise cancellation system for cancelling noise within an enclosed space, comprising:
at least one microphone for detecting acoustic noise, the at least one microphone being positioned outside of the enclosed space; a processor receiving input from the microphone and computing a noise cancellation signal; and at least one sound emitter receiving instructions from the processor and generating the noise cancellation signal, the at least one sound emitter being positioned outside of the enclosed space, such that acoustic noise detected by the at least one microphone is cancelled prior to the acoustic noise entering the enclosed space.
