APT Sound Testing Services undertake UKAS accredited Part E sound testingthroughout London and the UK. We have extensive knowledge regarding the way different materials and construction methods can influence the results of a sound test Women's Jake Bailey Jersey , to ensure your company achieves complies with Sound Testing Regulations Part E.

Pre completion sound testing under part E has been a mandatory requirement since July 2003. All new build properties and conversions which were built after this date require 10% of each party wallfloor construction type to be tested. Sound Testing is to be carried out between pairs of rooms separated by party walls or floors. In usual circumstances the rooms to be sound tested will be the living rooms and bedrooms, which are classed as the two main habitable rooms.


The sound test procedure involves setting up a noise source in a room on one side of the party wall or floor and measuring the noise on both sides of the partition.


Airborne sound tests may also be required between horizontally and vertically separated pairs of rooms. The sound tests are undertaken by using a sound source, amplifier and loudspeaker to generate a high noise level in one room (the source room). Noise measurements are then taken in both the source and receiver rooms using a prescribed number of source and microphone positions. The background levels in the receiver room are measured and the reverberation time in the receiver room is also measured. From the results, the airborne sound insulation (DnT Women's Hjalte Froholdt Jersey ,w + Ctr) is calculated and compared to the requirements of Approved Document E.


For vertically separated rooms, an Impact sound test may also be required. This sound test is undertaken using a tapping machine which drops a series of weights onto the floor of the upper room. The noise level in the lower (receiver) room is measured for a prescribed number of source and microphone locations. The background levels in the receiver room are measured and the reverberation time in the receiver room is also measured. From the results, the impact sound insulation (LnT,w) is calculated and compared to the requirements of Approved Document E.
