Estimator

Noise Reduction Estimator

Estimate resulting noise level after adding wall isolation.

Enter the noise level in the source room and the STC rating of the partition. Returns an approximate received level in the adjacent room. Useful for guest-room isolation and home-theatre bleed calculations.

40 (quiet)75110 (cinema)
e.g. voice ~60 dBA · TV ~70 · home theatre ~90 · rock concert ~110

Received in next room

27 dBA

Wall STC: 48

Inaudible / at noise floor.

Ambient residential floor ~ 30-35 dBA. Speech becomes clearly intelligible around 45 dBA.

Approximation only — assumes airborne transmission through the wall only. Real-world isolation is often limited by flanking paths (HVAC, doors, unsealed penetrations). For a spec-grade estimate, send us the room brief.
