Soundproofing Consultancy / Sound Insulation Testing

At AF Acoustics we offer sound proofing consultancy and sound insulation testing, to ensure that your floors and walls meet the required sound insulation levels. We have many years of experience in soundproofing walls and floors and are able to tell if a wall or floor will meet the required standards, and if not, we would be able to give advice to ensure that it does.

In July 2003 the new approved document E of the building regulations came into force which required all new build dwellings and building conversions to be built with a minimum standard of sound insulation. The regulations state that separating party walls and floors must meet both airborne (speech, television sound, etc.) and impact (footstep noise, etc.) sound insulation standards. The regulations apply to all houses, flats, student residences, care homes and hotels.

The building control department of the Local Authority may ask builders or property developers to carry out sound insulation testing in order to confirm compliance with these latest standards.

We provide sound insulation testing for building regulations compliance and can help to ensure your development is signed off promptly.

Sound insulation testing is the method used to measure the resistance of sound provided by an element of a building (such as a floor or wall) between dwellings. It essentially measures the effectiveness of the sound proofing treatment installed as part of a build or property development.

It has been a mandatory part of the building regulations for new build and refurbishment projects since approved document E was revised in 2003.

Sound insulation testing, or sound testing as it’s also called, is a method of testing a party floor or party wall structure to determine its acoustic performance in accordance with recognised British Standards as set out within building regulations approved document E.

How is sound insulation testing carried out?

For airborne sound tests, two individual speaker positions are used for each source room, with a total of ten individual 1/3 octave band measurements recorded for both the source and receiver rooms. Measurements are then made to monitor the levels in the receiving room of the tested partition in question. This gives a basic level difference between source and receiver rooms.

This basic level difference is then ‘corrected’ to allow for the reverberation time (the time taken, in seconds, for a noise source to decay by 60 dB) and the existing levels of background noise monitored whilst in the receiving room.

All tests are carried out in full accordance with BS EN ISO 140-1998 parts 4 (airborne) and 7 (impact), and the calculation of all single figure results are done so in accordance with BS EN ISO 717:1.
