Noisy retail spaces below living units are not uncommon. Airborne noise moving upward into the living space can be a problem.
Floors - The Model RIM roll-out isolation material floating a concrete slab creates a high STC assembly.
Ceilings - Ceilings suspended from concrete deck can use any of the following models depending on allowable ceiling drop and low-frequency isolation requirements. Note: Springs outperform pads as ceiling isolators for attenuating low-frequency sound.
Walls - The top of the walls in the noisy room below need a resilient restraint bracket assembly if they extend to the deck/floor above. This controls sound flanking around the ceiling assembly. See Model IPRB restraint brackets and Model Wallmat Resilient Partitions.
Noisy space next to a quiet space common in community centers and some retail where recreation and fitness activity rooms are adjacent to quiet rooms require high STC walls.
Walls - Model IsoMax for high STC single-wall assemblies. Model PSB or Model KWSB for double-wall assemblies.
