Description

One-way silencing wall filling material
Technical Field
The invention relates to the field of noise reduction and environmental protection, in particular to a unidirectional silencing wall filling material.
Background
Noise is a type of sound that causes irritation or is too loud and harmful to human health. From the viewpoint of environmental protection: all the sounds which obstruct people from normally resting, studying and working and the sounds which interfere with the sounds to be heard by people belong to noises. From the physical point of view: the noise is the sound produced when the sounding body does irregular vibration. Noise pollution can be classified according to the mechanical characteristics of the sound source: noise from gas turbulence, noise from solid vibration, noise from liquid impact, and electromagnetic noise from electromagnetic action. Noise can be classified by the frequency of sound: low frequency noise of <400Hz, medium frequency noise of 400-1000 Hz, and high frequency noise of >1000 Hz. The attribute of noise variation according to time can be divided into: steady state noise, unsteady state noise, heave noise, intermittent noise, impulse noise, and the like.
The existing silencing material filled in the wall body is generally sound-proof in two directions, namely, the inside and the outside, and is not different, so that the sound-proof mode is difficult to apply to special occasions, such as rooms of babies, wards and old people, and the like, namely, the sound-proof effect is good, and meanwhile, the requirement that people outside the rooms can hear sound and sound in the rooms in time is met, the sound-proof effect is poor, the sleeping effect of babies, patients and old people is easy to cause, the influence on the health of the bodies is great, the sound-proof effect is good, the people outside the rooms can not hear the sounds of the babies, the patients or the old people in time, the requirement that the patients or the babies can not be found in time is caused, and certain potential.
Disclosure of Invention
1. Technical problem to be solved
In view of the problems in the prior art, the invention aims to provide a one-way silencing wall filling material which can be used for filling a sound box with sound in a one-way silencing mode, wherein the sound box can be used for filling sound in a one-way silencing wall from inside to outside through the arrangement of a plurality of conch-shaped two-way sound tubes, the sound is conducted to the thin end part through the thick tail end, the inner diameter of the thin end part is larger, so that a better sound amplification effect can be achieved, meanwhile, sound is transmitted from the thin end part to the thick tail end part from outside to inside, so that the sound is reflected by the inner walls of the thin end part and the thick tail end for multiple times, the effective silencing effect is achieved, and the indoor and outdoor differential sound insulation effect can be realized by matching the action of the semi-sound insulation plate, thereby effectively improving the application range of the sound insulation material, leading indoor people not to be interfered by external noise, leading outdoor people to find the indoor sound and the indoor sound in time, and then can reach the effect that reduces certain potential safety hazard when improving the indoor people quality of having a rest.
