Abstract

The invention provides an environment noise elimination method and system and a mobile terminal. The environment noise elimination method comprises the steps of enabling a microphone of at least one mobile terminal to face the position to be subjected to noise insulation so as to acquire noise; analyzing the acquired noise and generating corresponding noise elimination waves, wherein the noise elimination waves are identical to the acquired noise in wave amplitude and frequency but opposite in phase when being propagated from the mobile terminal to the position to be subjected to noise insulation; sending the noise elimination waves to the position to be subjected to noise insulation through a loudspeaker of the mobile terminal so as to offset the noise; or using the mobiles terminal added at the position to be subjected to noise insulation and used for detecting the noise elimination effect after noise elimination as a detector, feeding back a result in a WIFI or Bluetooth mode or other wireless connecting modes for further regulation of noise elimination noise wave generation and enhancing noise elimination efficiency. The environment noise elimination method and system can achieve the scheme by utilizing the mobile terminal so as to facilitate carrying and achievement, and the problem that an existing noise elimination system is inconvenient to carry and the like is well solved.

Description

technical field [0001] The present invention relates to the technical field of noise elimination, in particular to an environment noise elimination method, system and mobile terminal. Background technique [0002] Environmental noise has caused many adverse effects on people's work / life. At present, most of the noise shielding is through sound-absorbing materials and corresponding considerations in architectural design. This method cannot be moved, let alone carried. There are also some designs of noise shielding equipment, but all require some complicated devices and are not easy to carry. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an environmental noise reduction method, system and mobile terminal, through a mobile terminal-based solution to solve the above-mentioned problems of complex structure and inconvenient portability of the noise shielding system in the prior ...
