北京墻面防撞軟包專業(yè)生產(chǎn)廠家生產(chǎn)的墻面防撞軟包的吸聲原理當(dāng)吸聲軟包和結(jié)構(gòu)的自振頻率與聲波的頻率*時(shí)，發(fā)生共振，聲波激發(fā)吸聲材料和結(jié)構(gòu)產(chǎn)生振動(dòng)，并使振幅達(dá)到一定程度，從而消耗聲能，達(dá)到吸聲的目的，因此共振吸聲材料和結(jié)構(gòu)的吸聲特征呈現(xiàn)峰值吸聲的現(xiàn)象，即吸聲系數(shù)在某一個(gè)頻率達(dá)到一定程度，在離開這個(gè)頻率附近的吸聲系數(shù)逐漸降低，在遠(yuǎn)離這個(gè)頻率的頻段則吸聲系數(shù)很低。

When the resonance sound absorption structure soft and favorable frequency of self vibration frequency and acoustic absorption principle, specializing in the production of Beijing wall wall collision soft soft anti-collision manufacturers, acoustic absorption material and structure vibration, and the amplitude reaches a certain degree, so as to reach the purpose of energy consumption, so the sound absorption characteristics of sound absorption, resonance absorption the materials and structure of the peak absorption phenomenon, namely the sound absorption coefficient reaches a certain level in a certain frequency, the sound absorption coefficient decreased gradually out of the frequency, in this frequency band is far away from the sound absorption coefficient is very low.
Specializing in the production of the Beijing wall collision roolls manufacturers
Anti collision wall soft cloth, leather and other outsourcing perforation with a breathable, soft, tension when the elastic characteristics of these materials and the air layer behind the formation of resonance system, near the resonant frequency acoustic absorption. Generally, the resonance frequency is between 200Hz~1000Hz, and the absorption coefficient is 0.3~0.4, which can be generally regarded as medium and low frequency sound absorption materials. The common models are square angle, fillet, bevel angle and big bevel angle. Commonly used specifications: 1200X600X25mm, 1200X600X50mm, 600X600X25mm, 600X800X50mm and other specifications, special-shaped can be size processing, the price according to the actual size of the customer to quote production completed.
Specializing in the production of the Beijing wall collision roolls manufacturers
The scope of application of wall anti-collision soft: products are widely used in the construction field; hall, lounge, schools, theaters, concert halls, gymnasium, office buildings, conference room, meeting room, reception hall and various cultural venues. The wall has a variety of soft collision finishes for the different needs of customers, at the same time, Ruixin company supplies sound-absorbing cloth acoustic board, wooden sound-absorbing panels, insulation board, anti-collision roolls, space absorber, plant fiber sound-absorbing sound-absorbing board slot, spraying, etc. the ho activities off the acoustic material.
