Sound absorbing materials and sound insulation materials are currently two ways of indoor noise reduction effect, through the sound absorbing board led by sound absorbing materials and sound insulation materials led by sound insulation panels to achieve modern indoor and outdoor noise reduction, the two noise reduction methods have a gap in principle, but in the effect and decorative performance has a better performance, so for modern sound absorption we need to start from these ways to develop an in-depth understanding.

Sound-absorbing materials: usually materials with holes, there are special cases of thin sheet materials without holes. When the sound wave reaches the surface of the sound-absorbing material, the sound energy generates frictional vibration in the air in the void of the sound-absorbing material, which converts the sound energy into heat energy and consumes. The best sound-absorbing materials can only absorb a few decibels, but an ordinary sound-insulating material can achieve a sound insulation effect of several tens of decibels.

In engineering, the goals and focuses of sound absorbing materials and sound insulation materials are different, and the goal of sound absorption treatment is to reduce the repeated reflection of sound in the room, that is, to weaken the reverberation sound in the room, and to shorten the duration time of the reverberation sound, that is, the reverberation time; In the case of continuous noise, this attenuation is manifested as a reduction in the indoor noise level, which is the same architectural space as the sound source absorbing material. For the sound coming from the adjacent room, the sound-absorbing material also plays a role in attracting, which is equivalent to improving the sound insulation of the envelope.

First, the sound-absorbing material is to absorb the artificial noise, such as KTV, bar, home theater, concert hall, recording studio, etc., the sound-absorbing materials used are porous wood sound-absorbing board, inorganic fiber spraying, grooved wood sound-absorbing board, polyester fiber sound-absorbing board, fabric soft bag sound-absorbing board, sound-absorbing cotton, etc.
Second, the sound insulation material is to isolate the noise produced by the outside world, and not let the noise go out, such as home theater, KTV bar, concert hall, statement hall, etc., the materials used are sound insulation wall, honeycomb sound insulation board, sound insulation felt, sound insulation board, etc. Sound-absorbing materials and soundproofing materials are relatively soundproof materials will be better, if the combination of sound-absorbing and soundproofing materials, that than
It is better to only do sound absorption and sound insulation, and there are several features:

1. The decoration can be used flexibly, and the aesthetic taste will have a good effect according to their own planning.
2. The sound absorption and sound insulation effect is very good, which can avoid noise troubles and complaints from neighboring citizens.
3. The role of audiovisual music is more realistic and beautiful.

Summary; Nowadays, the sound absorbing and sound insulation materials selected by the majority of customers are: grooved wood sound absorbing board, grille sound absorbing board, soft package sound absorbing board, hole wood sound absorbing board, polyester fiber sound absorbing board, etc. These materials are widely used, and then have been loved by the majority of customers.
