Cristalla Condominiums



SSA Acoustics provided acoustical design recommendations for all aspects of the 22-story, 197-unit Belltown condominium tower.


Mixed-use condominium projects are the most complicated projects. These projects have the most discerning new owners, expecting that the smallest of noise sources be eliminated. We worked with the team at Weber + Thompson to meet HUD Grade 1 guidelines in design and to eliminate mechanical noise from rooftop equipment to sensitive penthouse units below.


Under HUD guidelines, the walls and ceilings of the Cristalla project were designed to provide the maximum desired acoustical privacy between units. Designing the hallways, stairways, elevator shafts, and equipment spaces for sound isolation are equally important. From flooring materials and plumbing isolation to HVAC noise and vibration control- all materials and units were reviewed for quality.
