Walls & Floors – 43dB

Impact Sound Insulation (LnTw+Ctr)

Floors – 64dB

What are the requirements for Sound Insulation Testing

Sample testing must be carried out of the walls and floors of the development to ensure that the above standards are met. A minimum of one test must be undertaken between the floors and walls of one bedroom and one living area. If the dwellings do not have party floors, then only party walls must be tested.

One set of test consists of the below;

• 2x Airborne wall tests
• 2x Airborne floor tests
• 2x Impact floor tests

Building Regulations Part E states that a minimum of one set of tests should be carried out for every 10 dwellings, therefore 10 dwellings would require one set of tests, 20 dwellings two sets of test and so forth.

How is the testing carried out?

Sound Insulation Testing is carried out using sound level meters and dodecahedron speakers to emit pink noise at approximately 100dB, the sound level meter is then used to take readings of source and receiver rooms to determine the reduction of sound. along side this, additional reverberation measurements and background measurements are taken to ensure the readings are through the partition only.

Impact testing is conducted using a tapping machine to replicate impact on the room above the receiving room, the sound level meter is then used to determine the reduction in impact sound from the floor partition.

Certification

Next day certification is available for our sound insulation testing, the reports provided will be everything required to satisfy Building Control as long as all of the tests have met the standard in Building Regulations Part E.
