This is Mr.I of Shizuka Co., Ltd..
In our internal meeting, we installed the SHIZUKA Stillness Panel (SSP) behind the speaker and compared sounds. We placed a small speaker on the desk and played sounds with Bluetooth. The sound is echoing compared to the environment at home. We tried is SSP(500 mm×500 mm size), SSP for corner placement, SSP for prototype, and nonwoven fabric sound absorbing material. In addition, we played classic, bossa nova, techno, Japanese music, jazz music randomly as a sound source and compared the difference.
Here are some impressions from the experimenter.
☆ By putting a sound absorbing panel, the sound level becomes large although you are not raising the volume, and the three-dimensional feeling of sound increases.
☆ The best way to hear is using the SSP for corner placement. Steady sound absorption is carried out.
☆ Since non-woven fabric sound absorbing material alone can not insulate sound, it is difficult to determine whether or not it is absorbing sound. A standing wave is generated even if it stands independent from the wall.
☆ The distance between the speaker and the sound absorbing panel increases by about 10 cm away from the nearest, the presence of the sound increases.
☆ Techno music (which has bass and treble mixed) makes the difference of sound the most clear.
If you are arranging the sound field for your home, you will see a great effect by using a sound absorption panel. Please try it by all means.
