iwasemi RC-α' is a transparent acoustic panel developed applying acoustic meta-material technology. Due to its transparency, it can be installed on commonly used glass walls in meeting rooms. It is designed to primarily absorb frequencies ranging from 500Hz to 1000Hz, which encompass the human voice's frequency. Our transparent acoustic panels offer improved acoustic performance in meeting rooms while also capitalizing on the aesthetic benefits of glass features in their design. 'iwasemi RC-α' applies Pixie Dust Technologies' original acoustic meta-material technology(Patented in Japan and patent applications have been filed in some countries including USA) and it achieves both high transparency and high sound absorption coefficient.
