Environment-friendly sound insulation wall for communities

Abstract

The invention discloses an environment-friendly sound insulation wall for communities. The wall includes a mortise, a sound insulation main body, a tenon and an active noise reduction system; the leftside of the mortise is provided with the sound insulation main body; the sound insulation main body is fixedly connected to the mortise; the left side of the sound insulation main body is provided with the tenon; the tenon is fixedly connected to the sound insulation main body; the internal of the tenon is provided with the active noise reduction system; the active noise reduction system is embedded in the tenon; the surface of the active noise reduction system is provided with a concave-convex noise attenuation board; and the concave-convex acoustical panel is tightly attached to the activenoise reduction system. The active noise reduction system is arranged at the internal, an acoustic wave generator can emit sound waves with an opposite phase and identical frequency and amplitude withregard to noise, so that phase cancellation can be realized, and noise can be radically eliminated; and the soundproof board is provided with the mortise and the tenon, and the mortise and the tenonare connected to each other through an embedded manner, so that the problem of infirm contact of joints can be well solved.

Description

technical field [0001] The invention relates to the technical field of sound insulation equipment, in particular to an environment-friendly sound insulation wall for residential quarters. Background technique [0002] The sound insulation board is a section that acts on the sound insulation effect. It is classified into sound insulation of buildings and structures. The sound insulation board can not block the sound of all frequencies. Objects have a natural resonance frequency, and the sound close to the resonance frequency of the object. The sound insulation effect is significantly reduced. The sound insulation board has the difference between air sound insulation and vibration sound. The air sound insulation board is the plate that blocks the sound transmitted in the air. panels and systems for sound propagation in monolithic houses). [0003] However, the sound insulation structure of the existing environment-friendly sound insulation walls is simple, and most of them ad...

AI Technical Summary

Problems solved by technology

[0003] However, the sound insulation structure of the existing environment-friendly sound insulation walls is simple, and most of them adopt a single-layer sound insulation structure, which has a single function, and the sound insulation effect is not ideal, and there is no active noise reduction device, so the noise cannot be greatly reduced. The existing sound insulation panels are difficult to install, and the seams It is easy to leak sound, which makes the sound insulation board useless
