Continuous arc steel plate reflecting sound-proof device

Abstract

A continuous arc steel plate reflecting sound-proof device comprises high-quality continuous arc steel plates. A concave face of each continuous arc steel plate faces a noise source. The continuous arc steel plates are fixed on a metal truss. The area of a sound-proof operating unit is reduced greatly. The structure of continuous arc steel plates can convert waveform. Great reduction of the area of the sound-proof operating unit avoids mutual coupling effect. The continuous arc structure changes a wave path of reflected waves. A sound-proof operating face having an interfering function is formed and converts the waveform, loss of acoustic energy is increased, and the reflected wave is avoided returning to a vehicle.

Description

[0001] Technical field Environmental protection [0002] The invention discloses a continuous arc steel plate reflective sound insulation device, especially the continuous arc steel plate is fixed on a metal truss to avoid coupling, increase the quality of the sound insulation mechanism, and form a sound insulation working surface with an interference function at the same time to generate waveforms Transformation, increasing the loss of sound energy. Avoid reflected waves back to the vehicle body. Background technique [0003] At present, the well-known sound barriers and sound insulators are used by stacking large-area unit bodies upwards to produce coupling (interaction) effects, resulting in enhanced sound energy; the structural form arranged perpendicular to the ground makes the reflected waves return to the passing cars Body, the energy of the noise is further strengthened, and the function of noise reduction is lost. Contents of the invention [0004] The invention u...
