​Fully Accredited Sound Insulation Testing Performed by a Qualified Acoustic Consultant in Accordance with Building Regulations Approved Document E. ​​​​

Why do I need a Sound Insulation Test?
​

Building regulations require a minimum performance for Sound Insulation between adjacent spaces, for the purpose of providing reasonable living conditions for occupants. It is a mandatory requirement for both residential and non-residential buildings to be tested where Sound Insulation performance needs to be demonstrated. The regulations can be found in Approved Document E 2003 for England and Wales.

Airborne Test BS ISO 140-4

An omni-directional loudspeaker situated on one side of a separating wall or floor produces a range of frequencies, resulting in a diffuse noise. Noise levels are subsequently measured and documented on both sides of the partition.The amount of controlled noise transmitted from the source room to the receiving room is measured with a Sound Level Meter..

Impact Test BS ISO 140-7

A calibrated tapping machine is deployed to simulate footfall on the floor, and the noise produced is evaluated in the dwelling below with a Sound Level Meter.

Reverberation Time

Reverberation time is the time taken for sound to decay (RT60). It is used in the calculation to normalise reverberant contributions for both airborne and impact tests.

Test Report

Preliminary results can usually be shared verbally on the same day. The data is subsequently reviewed and organised into a report for both the client and the building control bodies.

When do we perform a Sound Insulation Test?

Preparing for sound insulation testing requires several important steps to ensure accurate results and compliance with acoustic standards. ​Proper preparation is vital for effective testing and achieving the desired soundproofing standards in your building.

All relevant construction tasks, including the installation of doors, windows, and fixtures that affect sound transmission, should be completed. The testing area should be cleared of furniture and other items to prevent any interference with acoustics. Gaps or holes in walls, ceilings, and floors must be sealed to avoid sound flanking. All mechanical systems, such as HVAC, need to be turned off to eliminate background noise during testing. Maintaining normal room conditions in terms of temperature and humidity is essential.

JG Acoustics will send you a requirements for testing guide to ensure your site can be ready for testing upon our arrival.
