Acoustic articulation / sound absorbing panel of 250 Hz or less

Hello, this is Mr.I of Shizuka Co., Ltd..

This time I will introduce “SHIZUKA Stillness Panel(SSP)” which gradually became popular as articulatory panel.
original article in Japanese (日本語の記事)

The SSP has aluminum fiber on the sound absorbing surface and is structured to absorb a wide frequency band. Usually, sound absorbing material is made of a single material such as urethane or glass wool. However,  SSP has become a specification that can absorb low frequencies that are not good at double structure. In the first place, sound absorption is a phenomenon that converts incident sound into thermal energy. Since the sound does not reflect as the amount of conversion increases, it is possible to efficiently absorb sound by performance or combination of materials. 

Also, if you want to absorb the part below 125 Hz, sound absorption is possible with a custom-made panel. 

The flutter echo changes depending on the height of the ceiling and the size of the room, but you should be able to feel the clarity of the room and the depth of the sound by placing multiple pieces.
