Sound Absorbing Material

1. Material: Usually medium density fiberboard (MDF) or other high-density wood materials are used.
2. Specifications:
1. Common sizes: 2440mm × 128mm, 2440mm × 197mm, etc. Other specifications can be customized according to needs.
2. Thickness: 12mm, 15mm, 18mm and other common thicknesses. The greater the thickness, the better the sound absorption effect.
3. Surface treatment:
1. Wood grain veneer: A common surface treatment method, the texture of imitation wood is beautiful and natural.
2. Spray painting: A variety of colors are available to meet different design needs.

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.
