What needs to be clarified
Assess airborne sound insulation between rooms and accessible transmission paths, comparing findings with the design and assessment criteria applicable to the property.
Materials to prepare
- Room plan and partition design with junction details
- Documents and photographs of concealed layers before finishing
- Access to both rooms and background-source operating information
What to compare
Use an applicable measurement method, controlling source, background and acoustic conditions in both rooms. Record dimensions, doors, sockets and accessible junctions. Compare frequency-dependent results with construction and consider flanking transmission. Local observations test explanations separately from the overall insulation assessment.
Possible outcome of the analysis
A measurement report may assess the measured indicator and probable weak areas; localized opening and improvement options need separate justification reflecting concealed-layer access.
Limits of the conclusions
A phone recording cannot replace sound-insulation measurement. Audible speech alone does not locate a defect; concealed layers may leave the transmission path uncertain.
