Block wall for soundproofing?

Piscina | Posted in General Questions on

I’m taking a space that I can install a block wall on two or 3 sides of the space. My floor is a slab not a post and pier so it can hold the weight. I could fill the block with cement or foam. Will that quiet down the inherant noise in a fairly public space?

    Piscina,
    The sound transmission class (STC) rating for an 8-inch block wall ranges from 44 to 55. More information here: SOUND TRANSMISSION CLASS RATINGS FOR CONCRETE MASONRY WALLS.

    To compare these STC ratings to the ratings of partitions with steel studs or wood studs, see this document: Acoustical Assemblies.
