Services
Sound Testing
Mandatory sound insulation testing for new residential developments ensures compliance with Approved Document E. Our ANC-registered engineers conduct pre-completion tests measuring wall and floor sound resistance. We provide certification for building control and BREEAM requirements using calibrated equipment and standardised methodologies.
Building Acoustics
Comprehensive acoustic design services optimise internal sound environments for schools, hospitals, and commercial spaces. We assess ambient noise levels, sound insulation, and room acoustics using proprietary software like CATT Acoustics. Our solutions meet Building Bulletin 93 and Health Technical Manual 08/01 standards while enhancing occupant comfort.
Environmental Noise
BS4142-compliant environmental noise assessments support planning applications and industrial noise management. We conduct baseline surveys, predict sound propagation, and design mitigation strategies. Our experts collaborate with local authorities to ensure compliance with National Planning Policy Framework requirements for residential and commercial developments.
Expert Witness
Court-tested expert witnesses provide noise and vibration evidence for legal proceedings. Our consultants prepare technical reports for public inquiries and tribunal hearings, covering noise nuisance cases, entertainment licensing, and industrial disputes. All witnesses maintain UK Register of Expert Witnesses accreditation.
Occupational Vibration
Hand-arm and whole-body vibration assessments ensure compliance with Control of Vibration at Work Regulations 2005. We measure exposure levels, calculate EAV/ELV thresholds, and recommend risk reduction strategies. Our reports include equipment-specific mitigation plans and work pattern adjustments to prevent HAVS and CTS.
