Soundproof Louver With M-Type Hood For Natural Ventilation Opening

Soundproof Louver With M-Type Hood For Natural Ventilation Opening

Sound insulation material reduces sound leakage from the inside and outside.

■ Sound insulation performance
A soundproof hood is installed on the wall between the sound source and where the sound is heard, with a numerical value indicating how much sound is blocked. The sound was measured according to JIS A 1428 and displayed based on "JIS A 1428 Annex 1."
■ Sash sound insulation level
There are four sash sound insulation levels according to JIS A 4706 represented by lines T-1 level to T-4 level. The criteria for determining whether a level is reached is if the sound transmission loss at the center frequency of 16 points exceeds the corresponding sound insulation level line. In addition, if the sum of the values below the corresponding sound insulation level line in each frequency band is 3 dB or less, the sound insulation level is given.
