Hello, this is Mr.I of Shizuka Co., Ltd..
Today’s article is about flutter acoustic guitar and sound absorbing panel.
※original article in Japanese (日本語の記事)
We received some photos from our customer who used our acoustic panel “SHIZUKA Stillness Panel (SSP)”. In recording sound and sound inside the soundproof room, it was in a state that accurate recording can not be done with internal echoes. Therefore, we reviewed the introduction of SSP. The soundproof chamber alleviates sounds from the outside and alleviates the internal sound from going out, but there is no change in the sound absorption in the room. Rather, the wall thickness increases to enhance the sound insulation performance, so the interior area is limited and flutter echo occurs more easily. By installing SSP, we were able to adjust the reverberation sound and create the optimum space for recording.
As an advantage of SSP, it is possible to install it after retrofitting. General sound absorbing materials (glass wool, sound absorbing urethane, etc.) are effective when attached to a wall or ceiling, but once it is installed it will be difficult to remove and the interior will be affected. In the case of SSP, you can choose with / without legs for standing, so you can install it at a free angle near the speaker. In the case without the legs for standing, we recommend mounting on the wall, but because we can obtain a higher sound absorbing effect than urethane, more accurate recording is possible.
So, please keep in mind, SHIZUKA Stillness panel may be the best answer to reduce the reverberation time in the soundproof room.
