High Performance Soundproof House for Very Low Frequency RIS-B (BSK-L2 type)

RIS-B (BSK-L2)

Concrete-filled panels for high-performance infrasound control, to reduce infrasound generated from primary processing machines (vibrating sieves) used in muddy water shield construction, etc.note (supplementary information) symbol(frequency 16Hz and 20Hz)!
Concrete-filled panels with significantly improved surface weight and rigidity have been developed. High sound insulation performance suppresses leakage of very low frequency sound.

Ultra-low frequency sound is "inaudible sound" with a frequency of less than 20 Hz. However, when the sound pressure exceeds a certain level, it has different characteristics from general construction noise, such as shaking the glass windows of houses and giving a feeling of oppression to the body and mind. In order to cope with this special sound, we have developed special panels that are specially designed to deal with very low frequency sound, which ordinary soundproofing panels cannot protect against.
