Core idea: Use design-stage opportunities that are difficult to retrofit.
Adjacencies
Separate quiet rooms from stairs, mechanical spaces and entertainment areas.
Specifications
Document complete tested wall, floor and ceiling systems.
Trade coordination
Electrical, plumbing and HVAC can bridge isolation.
Inspection
Photograph seals and resilient details before closing walls.
A practical planning sequence
- Describe the source, timing and frequency character.
- Trace direct and flanking paths.
- Set a realistic improvement goal.
- Compare complete systems and local requirements.
- Document the baseline and inspect details during work.
- Repeat the same test afterward.
