One product with the effects of insulation and sound absorption! Porous sound-absorbing material "Belacoust."

Insulation performance almost equivalent to glass wool! Compared to standard products, it is possible to achieve over 33% weight reduction and more than 30% improvement in sound absorption performance. *Basic knowledge collection on sound-absorbing materials is currently available.

At our Bell Development, we design sound-absorbing materials tailored to the peak frequencies of sounds we want to absorb through acoustic analysis. Additionally, our sound-absorbing materials can achieve over 33% weight reduction compared to standard products and improve sound absorption performance by more than 30%. Moreover, our sound-absorbing materials excel in thermal insulation, with performance comparable to glass wool, maintaining a thermal conductivity of 0.037 [W/mK]. For example, they are effective as insulation materials within building partitions and internal walls. Depending on usage conditions, we can add necessary functions to the sound-absorbing materials, such as moldability, flame resistance, heat resistance, and water and oil repellency. 【Features】 ■ We can design sound-absorbing materials tailored to the frequencies of noise targets. ■ The sound absorption rate of the materials can be used to determine sound insulation performance. ■ Functional enhancements can be applied to meet the required performance specifications of each component. ■ The materials used include polyester fibers and others, considering environmental factors such as SOC and VOC, with no harmful substance emissions. *For more details, please download the PDF or feel free to contact us.
