Mat 15 specified to achieve acoustic compliance with UK Building Regulations

Hush Acoustics has supplied an acoustic rubber matting solution to a residential development in St Leonards on Sea which had failed to achieve acoustic compliance with UK Building Regulations.

The development was suffering from reverberation noise problems due to a separating timber stud wall between two bedrooms, as levels of flanking transmission sound were passing under the wall via the floor screed.

Hush carried out a sound test on the separating wall between the two bedrooms. The result was DnTw+Ctr 31dB, which meant that the wall failed the test.

Mat 15

To resolve the issue of flanking transmission sound, Hush specified its Mat 15 solution. Mat 15 is an engineered acoustic rubber matt with high mass levels to help reduce impact, airborne and flanking transmission sound levels.

Mat 15 was laid over the floor screed in both rooms.

The development was then re-tested and the result was DnTw+Ctr 44dB, meaning the wall had passed the test and complied with Approved Document E (England & Wales) of the UK Building Regulations.

Whilst this result would be considered average in most other buildings, the fact that it had improved from a poor DnTW+Ctr 31dB demonstrates the matting solution’s effectiveness.
