Device for reducing noise pollution of automobile horn and application of device

Abstract

The invention relates to a device for reducing noise pollution of an automobile horn and application of the device. The device is mounted on an automobile and comprises a digital signal controller, an audio coder-decoder, an environmental noise sensor, a press sensor, a power amplifier, a loudspeaker, a liquid display and a power interface. The application comprises: the audio coder-decoder detects and records environmental noise information sensed by the environmental noise sensor, and transmits the information to the digital signal controller, and simultaneously, the digital signal controller detects and records press information sensed by the press sensor; the digital signal controller outputs loudspeaker control information to the audio coder-decoder according to the environmental noise information and the press information; the audio coder-decoder receives and decodes the loudspeaker control information, and transmits the control information to the loudspeaker after passing through the power amplifier; and the loudspeaker makes a sound according to the loudspeaker control information. Compared with the prior art, the device for reducing noise pollution of the automobile horn has the advantages of safe guarantee, strong anti-interference capability and the like, and nose is reduced.

Description

technical field [0001] The present invention relates to a device and application for reducing noise pollution, in particular to a device for reducing noise pollution from automobile horns and its application. Background technique [0002] It is common for urban traffic noise to exceed the traffic noise standards formulated by the state, and it is the main source of urban noise pollution, which brings inconvenience and even harm to people's physiology, psychology, life and work. very strong. The methods and measures adopted at this stage to reduce the noise of car horns are mainly reflected in the restriction and prohibition of honking, etc. These methods or measures have a certain effect, but they are difficult to implement, inconvenient to manage, and the effect is not ideal. In addition, many control methods for car horn noise proposed from a technical level consider a single factor, and it is difficult to meet the requirements of reducing environmental noise without affe...
