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.

Referring to fig. 5-6, a plurality of single-opening muffling cylinders 8 are embedded in a sound-insulating plate 11, the plurality of single-opening muffling cylinders 8 and a sound-transmitting plate 12 are distributed at intervals, noise and noise outside can be effectively reflected by the plurality of single-opening muffling cylinders 8, the condition that the noise is transmitted into the filling material is effectively reduced, and the sound-insulating effect on the outside noise is further effectively improved, the single-opening muffling cylinders 8 are in a U shape with a large opening and a small opening, a polishing layer is arranged on the surface of the single-opening muffling cylinder 8, the inlet and the outlet of the single-opening muffling cylinder 8 are the same, so that the sound entering the single-opening muffling cylinder 8 is not easy to be continuously transmitted inwards, meanwhile, the polishing layer in the single-opening muffling cylinder 8 can improve the reflection speed of the outside sound, and further improve the efficiency of the reflected noise, the diameter of the opening of the single-opening muffling cylinder 8 is 1/3-1/2 with the largest inner, easily lead to 11 parts of acoustic celotex board wholly too spaciously, cause the syllable-dividing effect poor, the oral area undersize, external noise is difficult for getting into in the single mouthful of amortization section of thick bamboo 8, it is poor to lead to the reflection effect to sound, and 8 inner walls of single mouthful of amortization section of thick bamboo are smooth cambered surface, the sound of being convenient for constantly takes place to reflect and is consumed in single mouthful of amortization section of thick bamboo 8, there is not obvious edges and corners in the single mouthful of amortization section of thick bamboo 8 simultaneously, make the sound that gets into in the single mouthful of amortization section of thick bamboo 8 finally can come out from 8 oral areas of single mouthful of amortization section of thick bamboo after the multiple reflection, effectively reduce because of single mouthful of in the amortization section of thick bamboo.
Can be through the setting of a plurality of two-way sound section of thick bamboo 5 of conch form, when from inside to outside, sound is through thick tail end 51 to thin end 52 department conduction, thin end 52 internal diameter is great can play better public address effect, simultaneously from outside to inside, sound is from thin end 52 to thick tail end 51 department conduction, make sound pass through thin end 52 and thick tail end 51 inner wall reflection many times, reach the effect of effectual noise cancelling effect cooperation board acoustic celotex board simultaneously, can realize the effect of indoor outer difference sound insulation, and then effectively improve this acoustic material's application scope, when making indoor people can not receive external noise interference, outdoor people can in time discover indoor sound, and then when improving indoor people's rest quality, can also reach the effect that reduces certain potential safety hazard.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
