Color steel piercing sound-absorbing board mainly underside with circular hole in a metal plate, and the top surface of the metal plate for a shape into fine wavy surface, and the corresponding oval on wavy surface above the surrounding is concave on micro hole forming three pyramid;Accordingly, make the reflection of sound waves colliding disturbance attenuation, and at the same time, even if some sound waves through the three cone cone oval at the bottom of the micro hole, also will cause the acoustic transmission loss, so as to achieve a better sound-absorbing and faster effect.Perfect combination of modern architecture concept of the "green environmental protection, durable, beautiful, sound-absorbing, sound insulation effect is good, strong sex to install easy to use" etc, and widely used in airports, convention and exhibition center, railway, highway, studios, theaters, multi-function hall, conference room, hall, classrooms, and other public places.
The CWB is mainly used for wall panels.The use is more extensive.
The effect of a metal sound-absorbing panel on architectural acoustics
Architectural acoustics is the science of studying acoustic environmental problems in buildings.It mainly studies indoor sound quality and the noise control of building environment.
The basic task of building acoustics is to study the physical and acoustic processing methods of acoustic transmission in the room to ensure that the room has good hearing conditions.The study controls the noise and harms of the inside and outside of the building.
Acoustic design should consider two aspects, on the one hand, to strengthen the effective sound reflection in voice transmission, to make sound energy uniform distribution and diffusion within the architectural space, such as in hall hall timbre design shall ensure that all the audience are appropriate loudness.On the other hand, all kinds of sound absorbing materials and sound absorbing structures are used to control the reverberation time and the frequency characteristics of the rules, so as to prevent the echo and sound concentration.Metal sound-absorbing board including caigang perforated sound-absorbing board, perforated aluminum plate sound-absorbing board, perforated sound-absorbing aluminum veneer the sound-absorbing micro perforation plate is now part of the sound absorbing structure needed for large public buildings.
To deal with indoor sound quality, it is important to understand the influence of indoor space body and selected materials on the sound field.Also consider the relationship between acoustic parameters of the indoor sound field and the effect of subjective hearing, the subjective evaluation of sound quality.It can be said that the quality of the indoor sound quality is still the subjective feeling of the audience.The inconsistencies in subjective evaluation are one of the characteristics of the subject because of the difference between the individual and the taste of the audience.As a result, architectural acoustic measurements were studied.Explore the correlation of acoustic parameters and the audience of subjective feeling, and indoor acoustic signal of the relationship between subjective feelings and indoor acoustics standard method, is also one of the important contents of indoor acoustics.
In large hall building, often using electroacoustic equipment in order to enhance natural sound and improve of the uniform degree of direct sound, the circuit can also use the measures such as artificial delay, artificial reverberation in order to improve the effect of sound quality.Indoor amplification is an essential aspect of the sound quality design of large halls, so modern amplification technology has become an integral part of indoor acoustics.
But even if there is a good indoor sound design, if the noise is seriously disturbed, it will be difficult to get a good indoor hearing.In order to ensure the function of the building and ensure the normal life and working conditions, it must also reduce the influence of noise.Therefore, it is another important aspect of architectural acoustics to control the noise of building environment and to ensure that certain quiet standards are met within the building.
