Do You Know 3D Acoustic Panels?

  The selection of the   3D acoustic panels   should be decided according to the actual situation. The selection of the polyester acoustic panels should be similar to the sound frequency emitted by the sound source. The similar frequency is easy to produce resonance, so it is more convenient for the 3D acoustic panels to process the sound.The sound absorption effect is also more obvious. The position of the indoor sound source has a great impact on the sound absorption and noise reduction effect of the sound  absorption board. If the 3D acoustic panels is close to the sound source, the effect will be poor. The polyester acoustic panels and noise reduction effect of the sound from the hospital is better than that from the location of the source. 3D polyester fiber acoustic panels features: 1. Polyester acoustic panels with high quality, high density polyurethane as the base material, flame retardant or non-flame; retardant decorative fabric, fine processing; 2. Achiev...

About Sound Insulation and Sound Insulation Materials

  In daily life, every time the building is far away from the street or the noise pollution source double the distance, the noise can be reduced by 6dB, and the green trees in the community can reduce the noise by about 4dB.  Acoustic materials manufacturer   shares with you. Noise propagation Noise transmission can take two forms: airborne noise and solid-borne noise. 1. Airborne noise The most basic way of sound wave propagation is air propagation, and airborne noise is the noise that the outside noise is transmitted into the room through the air. A thick metal plate with small holes, the area of the small holes accounts for about 13% of the metal plate, when a sound hits its surface, nearly 97% of the sound will pass through. The ability of sound to propagate through pores is quite amazing, and a tiny crack can destroy a complete sealed acoustic system. Therefore, strict sealing of the room is very necessary to isolate air noise. 2. Solid-borne noise Sound can be trans...
