Designed to match the frequency of target noise! Porous sound-absorbing material 'Belacoustics'.
We propose sound-absorbing materials designed to incorporate required functions such as flame retardancy and water and oil repellency, tailored to the sounds you wish to absorb through acoustic simulation.
"Belacourse" is a high-performance porous sound-absorbing material that can be designed to match the peak frequency of noise sources. It is possible to add required functions such as moldability, flame resistance, sound insulation, noise reduction, and water and oil repellency. Additionally, it has thermal insulation performance comparable to that of glass wool, significantly improving the working environment when used as a substitute. 【Features】 ■ It is possible to design sound-absorbing materials tailored to the frequency of the noise source. ■ Sound insulation performance can be identified from the sound absorption rate of the sound-absorbing material. ■ Functional enhancements can be applied to the required performance of each specification part. ■ The material uses polyester fibers and others, considering the environment with no generation of harmful substances such as SOC and VOC. ■ Due to its excellent thermal aging resistance and flame resistance, it can be used in engine rooms of vehicles and construction machinery. 【News】 1. Noise countermeasures in ducts and predictions of their attenuation values. 2. Noise countermeasures in boxes and predictions of their attenuation values. *For more details, please download the PDF or feel free to contact us.
