What needs to be clarified
The task could examine whether documented floor changes relate to sound-insulation findings, separating impact noise, airborne sound and possible flanking transmission.
Materials to prepare
- Records and photographs of the floor before and during renovation.
- Room plans and information on partitions, junctions and the replaced covering.
- Earlier measurement reports and a log recording each episode’s time, room and activity.
What to compare
- Compare observation locations, conditions and use of neighbouring rooms.
- Examine available evidence of floor layers and rigid connections at junctions.
- Distinguish measured findings from assumptions about concealed construction and specify additional access needed.
Possible outcome of the analysis
The analysis could map examined transmission paths and documented changes, helping define the survey programme and questions about the renovation’s influence.
Limits of the conclusions
Without evidence of the former condition, a current measurement alone cannot establish the degree of deterioration. Identifying source and cause requires sufficient access and comparable conditions.
