Sound Testing
Creating quiet, comfortable spaces in homes and workplaces requires careful attention to acoustic performance. Sound testing is critical in ensuring buildings meet regulatory requirements for sound insulation while promoting occupant well-being.
What Is Sound Testing?
Sound testing evaluates the acoustic performance of buildings to ensure they meet specific noise control standards. These tests measure how effectively walls, floors and ceilings block airborne and impact sounds. The goal is to create environments where noise is minimised, improving occupant’s comfort. This process is essential for new builds, refurbishments and conversions to confirm regulations compliance with regulations. By conducting sound tests, property developers and builders can identify areas that need improvement to achieve the required levels of soundproofing.
Why Is Sound Testing Necessary?
Sound testing is a legal requirement for residential developments under Part E of the Building Regulations in England and Wales. This regulation outlines the minimum standards for sound insulation to reduce noise transmission between properties and within multi-unit dwellings. Beyond legal compliance, sound testing also benefits property owners and occupants by ensuring privacy and comfort. Poor sound insulation can lead to frustration, reduced productivity and disputes among occupants. Sound testing identifies these issues before they become long-term problems.
Understanding Part E Acoustic Testing
Part E of the Building Regulations is designed to manage sound transmission in residential and mixed-use buildings. It focuses on two main types of sound:
Airborne Sound
Airborne sound includes noises transmitted through the air, such as voices, music or television. To control this, walls and floors must achieve minimum resistance to airborne sound. The required standards are as follows:
- New builds: Minimum 45dB airborne sound insulation.
- Conversions: Minimum 43dB airborne sound insulation.
Impact Sound
Impact sound refers to noises caused by direct contact with a surface, such as footsteps on a floor. The regulations require that buildings keep impact noise within acceptable limits:
- New builds: Maximum 62dB impact sound level.
- Conversions: Maximum 64dB impact sound level.
By meeting these standards, buildings provide better soundproofing and reduce disturbances between neighbours.
Who Needs Sound Testing?
Sound testing applies to:
- New residential developments.
- Building conversions into flats or multi-use spaces.
- Commercial buildings changing use into residential properties.
If your project falls into any of these categories, it is critical to arrange sound testing to avoid delays in receiving compliance certificates.
Common Pathways for Sound Transmission
Sound can travel between rooms and buildings through various unintended pathways, known as flanking transmission. These pathways include:
- Unsealed gaps: Openings around plumbing pipes, wiring and ductwork can allow sound to pass through.
- Mortar joints: Poorly sealed wall joints can act as noise conduits.
- Flooring materials: Hard surfaces, such as tiles or wooden floors can transmit impact sounds without proper insulation layers.
Flanking transmission can compromise a building’s acoustic performance, even if walls and floors meet regulatory standards. Identifying and addressing these issues is crucial during the design and construction phases.

Frequently Asked Questions
Sound testing should be conducted before final inspections after completing all major construction work. This ensures the building is ready for occupancy and complies with regulations.
Our team will guide you through remediation options if your building does not meet the required standards. This may include installing additional soundproofing materials or addressing flanking transmission issues.
Effective soundproofing strategies include:
- Using acoustic insulation in walls and floors.
- Adding resilient channels to ceilings.
- Sealing all gaps and penetrations with acoustic materials.
Proactive planning during the design stage can significantly reduce the risk of non-compliance.
Our team specialises in providing reliable, efficient sound testing for all types of projects.
We offer:
- Expert advice: Guidance throughout the design and construction phases to prevent potential soundproofing issues.
- Comprehensive assessments: Detailed testing and analysis of walls, floors and ceilings.
- Actionable recommendations: Clear next steps if improvements are needed.
With years of experience in acoustic testing, we deliver results builders and developers can trust.
Reducing sound transmission requires careful planning and construction practices, including:
- Sealing gaps: Use acoustic sealants to close any openings around pipes and cables.
- Installing isolation layers: Add resilient materials under hard floor coverings to reduce impact sounds.
- Double-layering drywall: Installing additional layers of plasterboard can enhance airborne sound resistance.
These measures improve compliance with regulations and enhance the overall acoustic comfort of a property.
