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 invention relates to a device and application for reducing noise pollution, in particular to a device and application for reducing noise pollution of automobile horns. Background technique [0002] It is common for urban traffic noise to exceed the traffic noise standard formulated by the state. It is the main source of urban noise pollution. It brings inconvenience and even harm to people's physiology and psychology, life and work. It has aroused widespread concern and calls for control. Very strong. The methods and measures taken to reduce the noise of car horns at the present stage are mainly reflected in limiting and prohibiting the sound. These methods or measures have certain effects, but they are difficult to implement, inconvenient to manage, and the effect is not very satisfactory. In addition, many control methods for car horn noise proposed from the technical level consider relatively single factors, and it is difficult to meet the requ...

Problems solved by technology

The methods and measures taken to reduce the noise of car horns at this stage are mainly reflected in the limitation and banning of honks, etc. These methods or measures have a certain effect, but they are difficult to implement, inconvenient to manage, and the effect is not very satisfactory.

In addition, many control methods for car horn noise proposed from the technical level consider relatively single factors, and it is difficult to meet the requirements of reducing environmental noise without affecting traffic safety.
