The 100mm thick acoustic sound-absorbing body, which is double-filled with polyester fiber sound-absorbing cotton and sound-absorbing board and encapsulated with a solid wood frame, has achieved multiple advantages in terms of acoustic performance and practical value. The specific advantages are as follows

High-efficiency composite sound absorption, with better full-frequency coverage

The polyester fiber sound-absorbing cotton filled inside has a fluffy and porous structure, which has a strong adsorption and dissipation capacity for medium and low-frequency noise. The polyester fiber sound-absorbing board encapsulated on the outer layer is good at absorbing medium and high-frequency sound waves. The dual materials complement each other, and with a thickness design of 100mm, it can significantly improve the absorption efficiency of noise in the full frequency range of 125 to 4000Hz, with a noise reduction coefficient (NRC) of over 0.9. It is particularly suitable for professional acoustic scenarios that require precise control of reverberation.

The structure is stable and durable, with guaranteed long-term performance

The solid wood frame edge banding provides rigid support for the entire structure, effectively preventing the sound-absorbing cotton from collapsing or deforming due to long-term use, and also preventing the outer sound-absorbing board from being damaged by external force impact. The tight combination of the three-layer structure (wooden frame + sound-absorbing cotton + sound-absorbing board) ensures that the sound-absorbing body maintains stable acoustic performance during long-term use, and its service life is much longer than that of single-material sound-absorbing products.

Environmentally friendly and safe, suitable for all kinds of indoor environments

Both the internal sound-absorbing cotton and the outer sound-absorbing board are low-formaldehyde and environmentally friendly materials, meeting the GB18580-2001E1 standard. The solid wood frame, after environmental protection treatment, ha
