The difference between soundproof panels and sound-absorbing panels

The differences between soundproof panels and sound-absorbing panels include: different materials, different performance, different working principles, different installation environments, different noise reduction effects, and different sound reduction effects.

Different materials: sound-absorbing boards are generally made of porous materials, while grooved wood sound-absorbing boards are usually slotted on the front and perforated on the back. The perforated wood sound-absorbing board is filled with holes, and there are also many small gaps inside the soft package sound-absorbing board. The sound-absorbing material is basically "gap" material, while the sound-absorbing board must be high-density material, which is difficult to penetrate. The sound-absorbing board is made of high-density material, and its appearance is generally untreated, Usually composed of several boards or soundproofing felt.

Performance difference: In terms of usage performance, sound-absorbing boards have multiple functions such as moisture-proof, mold-proof, fireproof and non combustible, sound insulation and insulation, environmental protection, pest prevention, and corrosion resistance, while sound-absorbing boards have sound-absorbing noise reduction, water resistance, UV protection, lightweight safety, and dust resistance that can withstand typhoons of 10-12 levels.

The working principle is different: There are many open and irregular small holes inside the sound-absorbing board. After sound is heard in these small holes, the sound energy is converted into heat energy through friction with the holes, exerting the sound absorption effect. The sound-absorbing board, as the name suggests, is sound-absorbing. The sound-absorbing board is high-density board material, and sound is not easily penetrated through the sound-absorbing board, isolating the sound from the outside.

Different installation environments: In places with high reverberation noise and high requirements for sound quality, such as music halls, recording rooms, conference rooms, etc., using sound-absorbing boards can shorten the reverberation time to improve sound quality. However, in cases where the noise level is relatively high and cannot be effectively reduced internally, sound-absorbing boards can be used to reduce noise and isolate it in a space.

The noise reduction effect is different: the noise waves absorbed by the sound-absorbing board are consumed by friction with countless voids in the material, thereby reducing noise, while the sound-absorbing board has a considerable vibration reduction effect by reducing the permeability of noise and sound waves.
