Insulation performance comparable 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 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, along with more than 30% improvement in sound absorption performance.
Moreover, our sound-absorbing materials excel in thermal insulation, offering performance comparable to glass wool, with a thermal conductivity of 0.037 [W/mK]. 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 that match the frequency of the noise target.
■ We can specify sound insulation performance based on the sound absorption rate of the materials.
■ We can provide functional enhancements to meet the required performance of each specification area.
■ The materials used include polyester fibers and others, considering the environment by avoiding the generation of harmful substances such as SOC and VOC.
