What are the materials of perforated sound-absorbing board?

Sound is produced by the vibration of an object. Sound passes through the air to produce sound waves. When sound travels through the surface of the object, part of the sound will fall back, but other parts of the sound can pass through the object. that perforated suction plate material is what?

The sound-absorbing board is composed of perforated sound-absorbing board, perforated plate, through high-quality adhesive and aluminum honeycomb core directly bonded to the sandwich structure, and the sound-absorbing tube cloth is connected with the honeycomb core. Because the honeycomb core on the honeycomb aluminum plate is divided into many closed holes. This will obstruct the flow of the air stream and, therefore, the sound will also be blocked.

The decorative board material of the sound-absorbing board is gypsum, which is also one of the characteristics of gypsum board, because gypsum is insulated and has a good sound insulation effect. Sound-absorbing decorative board is developed on the basis of high-quality Bayer gypsum board, with large perforations and good sound-absorbing effect. There is also a mineral wool sound-absorbing board. This kind of board has many surface forms, and the board also has strong decoration. Its surface is made of knurled mineral wool board, often called caterpillar, with holes of different depths and shapes.

According to the material, it includes perforated sound-absorbing composite board, composite sound-absorbing board, perforated calcium silicate board, perforated gypsum board, perforated perlite sound-absorbing board, etc.

Many attraction boards are used in theaters or ktv and other places that require high sound quality. Most of the materials of the sound-absorbing board are relatively loose materials, but due to the uniqueness of these materials, when the sound is transmitted to its surface layer, it can be very Good to convert sound into heat.

　　Perforated acoustic panelIt has a wide range of uses. For example, the use parts include basement room sound-absorbing panels, conference rooms, office hall ceilings, hospitals, concert halls, theaters, recording studios, studios, monitoring rooms, conference rooms, gymnasiums, exhibition halls, song and dance halls, KTV rooms, family film and television halls, factories, mute rooms, courts, lecture halls, sound-absorbing textile mills in acoustic places such as interrogation rooms and factories with noise exceeding the standard, as well as sound-absorbing wall panels and ceiling panels in large public buildings that need sound absorption.
