Abstract

The invention discloses an active noise reduction and sound collection device sound barrier and a working method thereof, the active noise reduction and sound collection device sound barrier is arranged beside a railway or a highway and comprises a plurality of stand columns evenly arranged on a concrete base, and a top plate and a sound barrier plate which are oppositely arranged up and down areinstalled between every two adjacent stand columns; wherein a noise conversion device and a solar energy conversion device are arranged on the sound barrier plate, and the noise conversion device comprises an active noise reduction device and a sound collection device. The active noise reduction and sound collection device sound barrier has the advantages of economy, practicability, environmentalprotection, energy conservation, good noise reduction effect, full energy utilization, convenience in installation and easiness in maintenance.

Description

technical field [0001] The invention relates to the technical field of sound barriers, in particular to a sound barrier of an active noise reduction sound collection device and a working method thereof. Background technique [0002] Noise barriers refer to wall structures set up beside railways and highways to reduce the impact of traffic noise on nearby residents. Traditional sound barriers are designed to solve the problem of railway noise pollution. The noise reduction principle of the sound barrier is to insert a sound barrier between the sound source and the sound receiver. During the propagation of the sound wave, when it encounters the sound barrier, three phenomena will occur: reflection, transmission and diffraction, so that the direct sound can be prevented. Propagation, and make the propagation of sound waves produce a significant additional attenuation, so as to achieve the purpose of noise reduction. After decades of development, there are many types of sound b...
