Workplace Noise Surveys & Personal Dosimetry for UK Employers
Independent occupational noise assessments to the Control of Noise at Work Regulations 2005 — covering factories, engineering workshops, warehouses, construction sites and plant rooms. Clear action values, dosimetry data and hearing protection guidance you can defend to the HSE.

Services
Occupational noise services
End-to-end workplace noise assessment — from initial site walkover and dosimetry through to action plans, hearing protection validation and board-level reporting.
Workplace Noise Surveys
Methodical site-wide noise mapping and exposure assessments aligned with HSE methodology and ISO 9612.
Personal Noise Dosimetry
Body-worn dosimeters capture real shift-length exposure for representative roles and tasks.
Noise Exposure Assessment
Compare measured LEX,8h against lower and upper exposure action values and the exposure limit value.
Hearing Protection Assessment
Validate hearing protector selection using SNR / HML data and real-world attenuation factors.
Machinery & Plant Surveys
Source-by-source measurements for compressors, presses, CNC and rotating plant.
Noise at Work Regulations
Documentation, action plans and management-system support for the Control of Noise at Work Regulations 2005.

Action values
Lower, upper and exposure limit values explained
The Control of Noise at Work Regulations 2005 define two daily exposure action values (80 dB(A) and 85 dB(A) LEX,8h) and an exposure limit value of 87 dB(A). Each trigger point requires different employer actions — from information and training, through mandatory hearing protection zones, to engineering noise controls.
- • Lower exposure action value — 80 dB(A) / peak 135 dB(C)
- • Upper exposure action value — 85 dB(A) / peak 137 dB(C)
- • Exposure limit value — 87 dB(A) / peak 140 dB(C)
