Sound absorbing board

Soft-packed sound-absorbing panels are a material commonly used for indoor acoustic treatment and have multiple functions such as sound absorption, sound insulation, and decoration. Its core material is usually sound-absorbing cotton or glass wool, and the exterior is covered with fabric or leather. Through the soft surface and porous internal structure, it can effectively reduce the reflection and reverberation of sound and improve the indoor acoustic environment. Soft-packed sound-absorbing panels are widely used in conference rooms, cinemas, recording studios, offices, hotels and other places. They can not only improve the sound quality of the space, but also have certain aesthetic value.

Features of soft-packed sound-absorbing panels
1. Good sound-absorbing effect: The internal materials of soft-packed sound-absorbing panels are mostly porous sound-absorbing materials such as glass fiber, polyester fiber, mineral wool, etc., which can effectively absorb medium and high-frequency sounds and reduce noise and echo.
2. Strong decorative properties: The decorative materials with diverse appearances can be selected in different colors and patterns according to different design needs to achieve beautiful decorative effects and enhance the aesthetics of the overall space.
3. Environmental protection and safety: Most soft-packed sound-absorbing panel materials are environmentally friendly and harmless products, comply with relevant environmental standards, are non-toxic, tasteless and harmless to the human body.
4. Easy installation: The installation method is flexible, usually using frame fixing, glue sticking or screw fixing to facilitate construction and maintenance.
5. Fire resistance: Many sound-absorbing panel materials have fire resistance, meet fire protection grade requirements, and are suitable for use in public places.

Application scenarios of soft-packed sound-absorbing panels
Home theater: Improve the clarity of sound and enhance the immersion of the theater.
Recording studio: Reduce external noise interference and optimize the acoustics of the recording environment.
Conference room: Reduce sound reflection and improve speech clarity and voice transmission effect.
Theaters and concert halls: Improve the overall sound field distribution and enhance the audience’s sound experience.
Offices and hotels: reduce noise and improve the comfort of working and resting environments.

Common parameters
1. Material thickness: Common thicknesses are 25mm, 50mm, 75mm, etc. The greater the thickness, the better the sound absorption effect, especially the sound absorption effect in the low frequency band.
2. Sound absorption coefficient: Usually expressed as αw (sound absorption coefficient), the value range is between 0-1. The larger the value, the better the sound absorption performance. The sound absorption coefficient of soft-packed sound-absorbing panels with a thickness of 25mm is roughly 0.6-0.8, and the sound absorption coefficient of a 50mm-thick sound-absorbing panel can reach 0.8-1.0.
3. Size: Common sizes include 600mm×600mm, 600mm×1200mm, 1200mm×2400mm, etc. The size can be customized according to needs.
4. Density: The density of soft-packed sound-absorbing panels is usually between 48-96kg/m³. The higher the density, the better the sound insulation and sound-absorbing effect.
5. Fire protection level: Some products have Class A fire protection performance and can meet fire safety requirements.
6. Surface material: The surface material can be fabric, leather, non-woven fabric, etc. The color and texture can be freely matched according to the decoration needs.
7. Environmental protection level: The environmental protection level of soft-packed sound-absorbing panels usually meets E1 or E0 standards and is highly safe.

Conclusion
Soft-packed sound-absorbing panels not only perform well in sound absorption and insulation, but also have good decorative effects, which can improve the comfort and aesthetics of the space. With their easy installation and customizability, soft-packed acoustic panels are widely used in acoustic treatment in many commercial and residential locations.
