Is the soundproofing and sound absorbing material really useful, and the sound absorbing effect of t

Sound insulation should completely block the transmission of sound, so the material of sound insulation requires large density and quality, and it is airtight. Soundproofing can be done with many materials, such as bricks.

Acoustic panels. Acoustic felts and so on are fine. The sound insulation is directly proportional to the quality of the materials you use, and the higher the quality, the better the sound insulation. If there is a resonance, vibration isolation should also be considered. Of course, you have to think about the load-bearing. The way of construction is equally important.

Sound absorption is the reduction of reflections.

Avoid acoustic focusing.

Reduce or avoid sound defects, etc., so sound absorption will be microporous.

porous or resonator principle and other materials. Room sound absorption should first depend on the reverberation time you want and the volume of your room.

The amount of sound power is used to calculate the required sound absorption coefficient and sound absorption area. Then according to the results you calculate, you can match the sound-absorbing materials with the corresponding sound absorption coefficient. The sound-absorbing materials on the market will have a test report, and there is a sound absorption coefficient on it.

Soundproofing and sound-absorbing materials are certainly useful, but the acoustics are very professional, and the construction plan must be made according to the needs of the construction site, whether it is sound insulation or sound absorption.

Acoustic panels (different for different occasions).

Sound-absorbing cotton. Glass wool.

Rock wool. polyester cotton).

Perforated acoustic panels (plaster.

Cement. Calcium silicate.

Aluminum. And so on).

Acoustic panels (polyester, perlite.)

wooden, etc.).

Thickness. Material).

Spray coating. Sealants.

Acoustic damping coatings.

There are also some finished products.

Soundproof doors and windows. Noise barriers.

Soundproofed room. And so on and shock-absorbing materials are also used together.

Summary. Dear, hello: The sound absorption effect of sound insulation materials is not necessarily good, although some materials are called sound insulation materials, but in fact they do not play much role.

The sound insulation effect of sound insulation cotton is still very good, and sound insulation cotton is also a particularly common sound insulation material, which can be made into wall panels, ceilings, and can also absorb a large amount of sound energy in the room.
