Soundproofing Insulation Comparison and Installation

Compared to mineral wool batts, the spray foam does a good job sealing all air gaps where sound can leak, but doesnt have the near the density of mineral wool for sound insulation. The kind of foam that results in a rigid foam (closed cell) doesnt do much good for sound mitigation, but the kind that dries in a spongy state (open cell) is better.
