This would be very helpful JT but its not just about the floor slab.
- carpet gets ripped up and replaced with floor boards with high quality acoustic underlay.
- resident then turns on TV at same volume as always
- the echo chamber caused by the renovations and lack of soft furnishings (love the clean modern look) drives the next door neighbour mental.
- next door neighbour resorts to ranting on flat-chat blog
Any acoustic standards or ratings such as suggested must also consider wall thickness, materials and insulation as well as the floor slab.
