Abstract

In order to improve the practicability of active noise reduction of the actual scene in the community, the invention provides a kind of intelligent community environment monitoring system, including: community environmental noise detection unit, at least one fixed noise generating unit, at least one noise reducing device for mobile noise source and community environment, the community environment noise detection unit testing the decibel of stationary noise source and the noise generated by the mobile source, and controlling the community environment noise reduction device for active noise reduction. The intelligent community environment monitoring system of the invention can actively reduce the autonomous mobile noise source, and overcome the technical scheme in prior art and the defect of practical application where only noise of stationary source can be reduced, thus a relatively quiet area within the community environment is isolated out to improve the user experience.

Description

technical field [0001] The present invention relates to the technical field of mobile electronic equipment, and more specifically, relates to an intelligent community environment monitoring system. Background technique [0002] Active noise reduction refers to the technology of collecting environmental noise and generating a signal that is inverse to the noise and playing it back with a noise reduction device to offset the noise. The noise reduction system of a typical active noise reduction (ANC) headset consists of the following parts: 1) a microphone system for collecting noise; 2) an electronic control part for processing sound signals and generating noise reduction signals; 3) speakers A system for generating a noise-reduced sound signal. Most ANC systems employ one of two main structures: feedforward or feedback. For example, in the prior art, for example, Japanese Patent Publication No. JP078558A discloses a comfortable sleep device, including: a first sound pressur...
