Reverberation Noise in Common Areas 

Reverberation Noise in Common Areas 

Clients often ask us if they need to treat all the common parts within their block of flats to satisfy Requirement E3 (Reverberation in the common internal parts of buildings such as entrance lobby’s, corridors and stairwells.

Our usual answer to this is yes. The purpose of this Requirement is to protect residents from noise produced in reverberant common areas. The Requirement in Part E only applies to “corridors, stairwells, hallways, and entrance halls which give access to the flat or room for residential purposes”. To comply with this, it is recommended that absorbent treatment should normally be applied only to common areas onto which dwellings open directly. Sometimes this can be as easy as adding a resilient layer to the floor and/or adding an acoustic board to the ceiling.

Reverberation_Noise_in_Common_Areas

Often careful planning of apartment layouts can alleviate the need for extensive acoustic works, such as constructing the common areas of flats, such as corridors next to the common areas within the apartment block as long assuming normal usage of the common areas – more information on this can be found in paragraph 0.8 of Approved Document E (2003).

In all instances, planning an acoustically favourable dwelling from the design stage can help to reduce the number of noise problems that may occur even if your building passes the Sound Insulation Testing.

Also, if neighbours have varied working patterns, i.e. they work night shifts and arrive back in the early hours of the morning, allowing for sound absorption in common areas are particularly important.

We offer an acoustic design service, whether it’s accomplished during initial construction or during a refurbishment/renovation project. We also undertake UKAS accredited sound testing and noise surveys providing a ‘one stop’ solution for all your acoustic testing and design requirements throughout London and the South East.

Sound Insulation Testing Questions and Answers

Sound Insulation Testing Questions and Answers

We often get asked similar questions in regards to Sound Insulation Testing. To try help our clients alleviate their fears, we have tried to answer the most common questions:

Q. Is my project ready for a sound insulation testing? All plots should be at least at second fix stage – for further details please refer to our sound testing checklist

Q. Will the sound insulation testing disrupt other site works? During the sound testing, high levels of noise are generated but in order to make accurate test measurements, relatively quiet conditions are needed. Anyone working in the testing area will have to leave temporarily and any noisy works in the vicinity of the test rooms will need to be halted.

Sound_Insulation_Testing

Q. How long will the sound testing take? The time taken for sound testing varies with the site conditions, but generally a set of test on houses and flats takes about one to two hours so it’s over fairly quickly.

Q. Do I need to inform my neighbours of the sound insulation testing? If the building under test is attached in any way to occupied properties then you will need to inform the neighbours. To comply with Part E we need to gain access to the neighbouring properties to undertake the sound test. You will need to ensure that access is provided to the neighbouring properties throughout the sound Insulation testing.

Q. Will all internal and external doors and windows need to be fully installed? Yes, all internal and external doors must be fitted and operable prior to the sound testing

Q. What if I only have 110 volt and not 240 volt on site? Unfortunately we cannot undertake the testing; we will need 240V to undertake the sound testing.

Q. Can you offer advice on how to pass the sound Insulation testing? Yes, we can offer an acoustic design advice service. If you send through the relevant drawings such as sections, plans etc. during the earlier stages of construction, we can look at your design to check if the design is robust enough to pass Part E and/or there are any junctions or details where ‘noise flanking’ may occur. You can then change your design to reduce the chance of a sound test failure.

Q. Do you have a check-list we can download to help us prepare for thesound insulation testing? Yes, we send out the corresponding checklists for sound and air testing, to help you prepare for the testing.

APT Sound Testing is UKAS accredited to undertake sound insulation testing. We offer a comprehensive, seamless service from initial design development, right through to the final sound testing to achieve building sign off.

Improving Room Layouts can Reduce Noise Disturbance 

Improving Room Layouts can Reduce Noise Disturbance 

In all cases, the location and layout of rooms within dwellings will play an important role in relation to the levels of subsequent ambient or background noise that surrounds the occupants. In most cases much of noise is transmitted through the wall and floor partitions between habitable dwellings, such as flats and terrace houses.

Improving Room Layouts can Reduce Noise Disturbance 

Main ‘habitable’ rooms such as Kitchens or living rooms, which back onto bedrooms of the adjacent dwelling, are more likely to lead to noise complaints. Kitchen cupboards doors may transmit impact noise through to the bedroom next door through the dividing partition; this can lead to annoyance and frustration for the neighbour.

To reduce the chance of noise complaints, wherever possible hallways/corridors should be placed alongside the adjacent property to reduce the chance of noise transference and reduce the risk of sound testing failure. Failing this a kitchen should be places against a kitchen and bedrooms should back onto other bedrooms.

Improving Room Layouts can Reduce Noise Disturbance 

Planning a good acoustically favourable dwelling layout can help to reduce the number of noise problems that will occur even if your building passes the Part E Sound Insulation Testing.

If neighbours have varied working patterns, i.e. they work night shifts and arrive back in the early hours of the morning, i.e. the layout of the rooms use of rooms are particularly important.

APT Sound Testing can advise on all types of acoustic design, whether it’s accomplished during initial construction or during a refurbishment/renovation project. We also undertake UKAS accredited sound testing providing a ‘one stop’ solution for all your acoustic testing and design requirements throughout London and the South East.

Sound Flanking Pathways Identified During Sound Testing

Sound Flanking Pathways Identified During Sound Testing

Since Building Regulations Part E was introduced, we have literally undertaken thousands of sound tests throughout London and the South East; and as such we have built up considerable knowledge of typical sound flanking pathways. To help consultants and contractors we have comprised a list of the main Sound Flanking Pathways Identified During Sound Testing

  • Dividing Floor Partitions – Through Floor and Floor Joist Space (if insulation has not been installed or direct fixing to joists without a drop ceiling below the partition under test)
  • Dividing Ceiling Partitions – Above and Through the Ceiling Space (where an adequate acoustic break has not been carried on through the ceiling void)
  • Shared Structural Building Components – Floor Boards, Floor Joists, Continuous Drywall Partitions, Continuous Concrete Floors, and Cement Block Walls.
  • Through Structural Steel (structural steel beams are often a major cause of noise transmission as plasterboard is often fixed directly to the steel without sound breaks)
  • Plumbing Chases – Junctures between the Walls & Floor Slab Above or at the Exterior Wall Juncture (this should be filed with mortar etc. to add mass to this weakened areas.
  • Through Windows (if they are no double glazed or have secondary glazing as a minimum)
  • Fixtures & Outlets – Light Switches, Telephone Outlets, and Recessed Lighting Fixtures (if penetrations have been cut back to back with the opposite dwelling under test)
  • Structural Joints – Perimeter Joints at Wall & Floor, Through Wall & Ceiling Junctures (these should be filled with acoustic mastic.
  • Around the End of the Partition Through the Adjacent Wall (acoustic mastic should be used to seal this junction)

APT Sound Testing offer a ‘one stop’ design package for all types of acoustic design and sound testing in London, whether it’s accomplished during initial construction or during a refurbishment/renovation project.

Sound Insulation Testing London

Sound Insulation Testing London

Sound insulation testing is usually required on most London development/s between rooms or spaces that share a common area of separating wall and/or floor as stipulated in Building Regulations Part E for the passage of sound. The main aim of sound insulation testing is to ensure that minimum standards of sound resistance have not been compromised by poor workmanship and/or poor design.

The most common buildings that require sound Insulation testing are:

  1. Dwelling-houses, flats or rooms for residential purposes created by conversion of existing buildings or new build rooms for residential purposes.
  2. New build dwelling-houses and flats

You are normally required to undertake sound testing to each type of construction, i.e. if you have a mixture of brick, blockwork, timber and metal studwork walls all four types would need to be tested, followed by a 10% sample of the individual type of partition.

Sound Testing Houses in London
Sound Testing Houses In London

For example, if you have a project with 25 flats you would be required to do 3 x 6 pack of tests; each 6 pack contains 2 airborne wall, 2 airborne floor and 2 impact sound tests; however if any test failures occur, then the number of sound tests may need to increase on the development. When sound test failures occur, then the design and construction of the failed partitions will need to be revisited to try and evaluate the reasons for the failure; thereafter, agreement can be reached on how to rectify problem. We have carried our hundreds of acoustic design reviews, so we are well placed to help you overcome potential problems achieving compliance with Building Regulations Part E.
