What Is A Part E Test?

Part E was first introduced in 2003 and is an essential part of the Building Regulations set for England and Wales. Building regulations are put in place to ensure the safety of buildings and structures. Part E focuses on acoustic performance. The aim of Part E is to reduce the transfer of noise between dwellings.

At AF Acoustics, we conduct sound insulation tests for our clients. Our tests determine if a building meets or exceeds the standards set out in Part E. Many of our clients chose to involve us early on to ensure their wall and floor design will meet the required standards. We conduct tests as well as offer guidance and advice to help pass the requirements set out in Part E. Involving us early on tends to work out to be cheaper for the project as a whole.

Should a building fail Part E, we are able to offer guidance solutions to overcome any sound insulation issues. Our consultants are able to give recommendations based on the results of the assessment.

WHY IS A PART E TEST IMPORTANT?

Over the years, a huge focus has been placed on acoustics in the building. This is due to the damage sound can have on human health. Overexposure to sound can cause high-stress levels as well as sleep disturbances, hypertension, tinnitus and hearing loss. Lack of sleep can be very damaging for the overall well being of a person.

Part E states that buildings must be adequately protected from impact sound and airborne noise. A new build that does not meet standards set by Part E will be able to be lived in, however will be noisy at times.

HOW DO WE CONDUCT OUR SOUND TESTS?

A dodecahedron speaker generates white noise, which is normally placed in the largest room of the two rooms being tested. We use a sound level meter to take measurements of noise in the source and receiver room. The receiver room is often the room that is directly adjacent to the source room. Background noise measurements are also taken. The higher the background noise, the louder we need to set our source noise. Our source noise level needs to be 10dB higher than the background noise. We use our measurements to help determine the airborne noise.

Impact sound tests are conducted using a tapping machine. This machine is placed in the room above where measurements are being taken. As with airborne tests, impact sound tests are carried out in habitable rooms such as the bedroom or living room. The tapping machine above produces impact sound, which is then measured in the room below. These measurements determine if a building meets Part E of the building regulations.
