Acoustic floor matting for residential development

Acoustic floor matting for residential development

After a residential development in St Leonards on Sea failed to achieve UK Building Regulations acoustic compliance, Hush Acoustics was specified to supply an acoustic floor system.

The main problem with the development was with a separating wall between two bedrooms, where levels of flanking transmission sound were significant. Sound was clearly passing under the separating wall via the floor screed.

The sound test was carried out on the separating wall between the two bedrooms, one bedroom measuring 37m3 and the other was 29m3 in size, and no floor covering present. The test result was DnTw+Ctr 31dB, which means the wall failed the test.

As levels of flanking transmission were found to be high, Hush found a solution in the form of Hush Mat 15. This high performance acoustic rubber matting was laid over the floor screed in both rooms. The residential development was then re-tested and the result of the second test was DnTw+Ctr 44dB – which means it passed the test and complies with Approved Document E (England & Wales) of the UK Building Regulations.

Although this result would be an average result in most other buildings, the fact that it had improved from a poor DnTw+Ctr 31dB demonstrates the effectiveness of Hush Mat 15 as a solution to flanking transmission sound sources.
