Installing a Double Door AcousticMAX™ 50 Smoke Vent in a loud area would improve building occupants' insulation. It's helpful in the event of an interior fire and offers effective sound insulation, while its material is made of 14 gauge galvanneal steel and has a sound rating of STC 50 - OITC 39. Mineral wool is used for insulation, with a sound mat in the cover and curb for a total R-14 rating. The latch is a zinc-plated steel rotary intended to keep coverings shut against wind uplift of 90 psf. It's also UL 793 listed, with FM 4330 approval as an alternative.
