Which Building Reg’s cover Sound Insulation Testing?
So, which billings reg’s cover sound insulation testing in the UK? Approved Document E or Part E of the Building Regulations as its also known, focuses on the resistance to the passage of sound between dwellings.
Here are some key requirements of Part E when in comes to sound insulation performance between dwellings.
Key Requirements for airborne sound
Airborne Sound Insulation: This applies to walls and floors separating different dwellings. The minimum performance standards are:
New Build Developments:
- Dividing Walls: A minimum of 45 dB DnT,w + Ctr (decibels normalized to a standard reverberation time).
- Dividing Floors: A minimum of 45 dB DnT,w + Ctr.
Conversion Developments
- Dividing Walls: A minimum of 43 dB DnT,w + Ctr (decibels normalized to a standard reverberation time).
- Dividing Floors: A minimum of 43 dB DnT,w + Ctr.
Key Requirements for Impact sound
Airborne Sound Insulation: This applies to walls and floors separating different dwellings. The minimum performance standards are:
New Build Developments:
- Impact Sound Insulation: This applies to floors separating different dwellings. The maximum performance standard is:
- Floors: A maximum of 62 dB L’nT,w (impact sound pressure level normalized to a standard reverberation time).
Conversion Developments
Floors: A maximum of 64 dB L’nT,w (impact sound pressure level normalized to a standard reverberation time).
Sound Testing Process
Pre-Completion Testing (PCT): Sound insulation testing must be carried out before the building is completed to ensure compliance with Part E standards. The testing should be undertaken when the building is completed, but prior to the installation of carpets.
Qualified sound testers: Tests must be conducted by qualified professionals who are members of recognised bodies such as the United Kingdom Accreditation Service (UKAS).
Final documentation/sound test reports
Certification: Upon passing the sound testing, a valid sound test pass certificate is issued to confirm compliance with building regulations. This certificate is essential for obtaining building control approval.
