Description
Technical Field
The utility model relates to an abatvoix technical field, in particular to indoor fire-retardant for sound absorption combination formula cloth art abatvoix.
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.
Although the existing sound-absorbing boards are various in types, the poor phenomena of poor fireproof grade, fear of collision after decoration, easiness in damage, poor durability and the like generally exist, and the requirements of modern building development are difficult to adapt. In summary, there is a need to research a sound-absorbing board capable of absorbing multi-band noise simultaneously, so as to achieve the purposes of indoor sound absorption, noise reduction, high fire-proof level, high strength and more real sound effect.

The sound absorption principle is as follows: the sound is originated from the vibration of an object, the vibration of the adjacent air is caused to form sound waves, and the sound waves are transmitted to the surrounding in the air medium. When sound is transmitted into the surface of the member material, a portion of the sound energy is reflected, a portion penetrates the material, and a portion of the sound energy is converted from the sound energy into heat energy due to vibration of the member material or friction with the surrounding medium as the sound propagates therein, and the sound energy is lost, i.e., the sound is absorbed by the material.
The absorption low frequency that the combination of low frequency plate layer 5 in this embodiment and sound absorbing layer 4 can be fine can absorb partial high-frequency sound simultaneously, makes the utility model discloses the sound absorbing effect of abatvoix is better.
The utility model discloses not only can use in places such as cinema, still can use in indoor decoration such as at home, noise reduction effect is good.
