Introducing the results measured with a noise meter after attaching the Seion.

"Seion" uses an elastomer as an elastic material in the intermediate layer, absorbing vibrations that cause dragging noise. A 5.5 kg pipe-legged chair was dragged on P tiles and measured with a sound level meter. The version with Seion showed no vibration and demonstrated a soundproofing effect of about 29 dB. 【Verification Results】 ■ Seion ・50.2 dB (no vibration) ■ Standard product (hard resin) ・79.8 dB (vibration occurred)
