Description
Technical Field
The utility model relates to an abatvoix technical field, in particular to a combination formula cloth art abatvoix that is used for indoor noise reduction sound absorption.
Background
Noise pollution has become a modern global environmental problem, and is listed as four major worldwide pollutants, together with atmospheric pollution, water pollution and solid waste pollution. With the development of economy and science and technology, agriculture and industry tend to be more mechanized, and the transportation industry is developed day by day, but at the same time, the noise pollution is more serious. In the aspect of noise pollution control, noise reduction measures mainly include sound absorption technology, sound insulation technology, noise elimination technology and the like according to different implementation methods of noise pollution control technology. Sound-absorbing materials used as a passive control means have become one of the main methods for solving sound absorption and noise reduction. Therefore, the demand of the modern society for sound absorbing materials is increasing, and the performance requirements of the sound absorbing materials are also increasing.
In architectural acoustics, reasonable sound absorption is indispensable, and on a wall surface or an overhead flower which is not subjected to sound absorption treatment, a superposition phenomenon of multiple reflected sound and direct sound can be formed in the vertical direction and the horizontal direction, so that the indoor reverberation time is prolonged, and the sound cannot be dissipated for a long time, thereby causing the definition of indoor sound to be insufficient. Meanwhile, the rhythm feeling and the dynamic effect cannot be displayed in places with strong rhythm feeling requirements. For example, a cinema occasion needs a good sound effect, sound played by sound equipment is reflected by a wall, and after multiple reflections in the cinema, echoes and heavy sounds are caused, so that the listening effect is influenced. Therefore, it is necessary to install a sound-absorbing material for sound absorption to reduce reverberation time. Although the purpose of reducing reverberation time is achieved by installing sound-absorbing materials. Most of it absorbs high frequency tones, while the amount of absorption is small for low frequencies. Aiming at places such as a cinema and the like with high requirements on dynamic intensity, the bass is arranged to enhance the intensity of low accent and bass, so that the airplane can feel shocked by the power and energy when taking off. However, since subwoofers usually generate unnecessary resonance, the controllability of subwoofers is poor, and the low-accent sound is strong. The patient is disturbed by strong low-intensity sound for a long time, and is easy to feel uncomfortable, such as dizziness, headache, nausea, vomiting, stomachache and the like.
In summary, there is a need to research a sound-absorbing board capable of absorbing multi-band noise simultaneously, so as to achieve the purpose of more realistic sound effect while absorbing sound and reducing noise indoors.
For example, patent CN 204753867U discloses a low frequency sound absorbing board, which comprises a fiber board as a substrate, and a wood veneer compounded on the fiber board by using a hot-melt net film as an adhesive, so as to obtain the low frequency sound absorbing board. As another example, patent CN 210288736U discloses a low frequency board for cinema applications, which includes an acoustic board; the sound-absorbing board is made of polyester materials, sound-absorbing holes which are arranged in a staggered mode are formed in the sound-absorbing board, a PVC board is arranged above the sound-absorbing board, and the PVC board is fixedly connected with the sound-absorbing board. The sound absorption plate has the obvious sound absorption effect and can effectively reduce the environmental noise. However, all of them have a poor effect of absorbing high-frequency sound.
Patent CN 209975919U discloses an abatvoix for interior decoration, and it includes low frequency sound absorbing layer, interval layer and high frequency sound absorbing layer, low frequency sound absorbing layer and high frequency sound absorbing layer pass through the lug and the recess is fixed, low frequency sound absorbing layer is made by copper layer or aluminium lamination, high frequency sound absorbing layer is the perforated abatvoix of aluminium lamination honeycomb. Although this patent can absorb both low frequency noise and mid-to-high frequency noise; however, there is a disadvantage that, although the patent reduces the possibility that the low frequency sound absorbing layer and the high frequency sound absorbing layer are likely to interfere with each other in operation, the patent still has interference. Secondly, because the low frequency sound absorbing layer adopts the metallic material layer, there are relatively few holes, lead to whole sound absorbing effect not good. Meanwhile, the problems of flammability, complex installation process and the like exist.
