Sound Insulation Testing

Demonstrating compliance with construction standards

Approved Document E

Demonstrate that your development meets the requirements of Part E of the UK Building Regulations.

Investigatory Testing

Establish the performance of separating partitions and receive advice on remedial action.

Acoustic Privacy

Ensure that the spaces you build, provide adequate acoustic privacy.

The most recent, and current, assessment procedure for field tests of both airborne and impact sound insulation can be found within BS EN ISO 16283:2014. This standard is divided into 3 parts and covers airborne sound insulation, impact sound insulation, and façade sound insulation. As well as testing the acoustic insulation of a partition, a sound insulation test will involve assessing the background noise level with the receiver room, as well as understanding how the reverberation time has effected the measured results.

Completely Sound Limited are able to complete sound insulation tests for the purpose of investigation, building regulation compliance, or investigation of acoustic privacy.

Airborne Sound Insulation

The airborne sound insulation performance of a particular partition or building element will be dependent on many factors. Primarily, resistance to the passage of sound will be proportional to the mass of the partition system. The heavier the partition, the more energy that will be lost in transmitting vibrational energy through the system. While this component is critical, many of the issues that we attempt to resolve on site relate to flanking transmission paths, created by gaps that result from inadequate detailing during design, or other onsite factors during the construction process.

One key aspect to undertaking a sound insulation test, and the importance of having this completed by a suitably qualified acoustician, relates to investigating sources of failure and recommendation for remedial action. The frequency content of the sound, the location of the apparent leakage, and how the receiver level varies with different source positions, can all contribute to better understanding the source of the problem, and more importantly, how to fix it!

 

Impact Sound Insulation

While the sound that we experience is often airborne, the origin of that sound, and the path that sound takes to reach us, can often involve propagation through solid elements of the building. Understanding and assessing this transmission of vibrational energy is at the heart of an impact sound insulation test.

Whether it’s noise resulting from footfall, scraping chairs, or dropped items, we need to ensure that the vibrational energy that is passed into the floor does not cause disturbance below. To this end, it must be ensured that the vibrational energy is dampened or dissipated to an extent that it does not result in excessive airborne noise levels in adjacent areas of the building. An impact sound insulation test will produce a standardised and consistent level of impact onto a partition surface, the resultant radiated sound pressure level of which can then be measured and assessed against the relevant standards or guidance documents.

Approved Document E

The requirements of Approved Document E differ slightly from the requirements of ISO 16283. Approved document E of the UK building regulations require that results of tests shown in tabular and graphical form are derived according to the relevant part of the BS EN ISO 140 series and rated in accordance with the associated sections of the BS EN ISO 717 series.

In order to achieve sign off from building control, it is important that your appointed acoustician has an appropriate grounding in the testing requirements for your project. For this reason, all consultants working with or for Completely Sound Limited will hold relevant academic qualifications in acoustics, and will be members of the industries professional engineering institution, The Institute of Acoustics.
