What Are Noise Assessment Reports?
Noise reports document the measurement and evaluation of noise exposure levels that workers experience during construction activities. They identify which tasks and equipment generate noise above the action values set out in the regulations, which workers are at risk, and what control measures are in place to reduce exposure. Reports include noise measurement data (in decibels), exposure calculations (daily or weekly), and recommendations for hearing protection zones, equipment selection, and work scheduling to minimise exposure.
Why Noise Assessment Reports Matter
Noise-induced hearing loss is permanent and irreversible. It is one of the most common occupational health conditions in UK construction. Employers who fail to monitor and control noise exposure face enforcement action from HSE, including improvement and prohibition notices. Workers suffering hearing loss can bring civil claims for damages. Beyond the human cost, uncontrolled noise also affects communication on site, increasing the risk of accidents when workers cannot hear warnings or instructions.

Frequently Asked Questions — Noise Assessment Reports
What are the noise action values in the regulations?
The lower exposure action value is a daily or weekly average of 80 dB(A) — at this level, employers must make hearing protection available. The upper exposure action value is 85 dB(A) — hearing protection becomes mandatory and noise reduction measures must be implemented. The exposure limit value is 87 dB(A) taking account of hearing protection worn.
What equipment commonly exceeds noise action values on construction sites?
Equipment frequently exceeding 85 dB(A) includes concrete breakers, angle grinders, circular saws, hammer drills, piling rigs, and demolition machinery. Even tasks like nail guns and disc cutters can exceed action values. The HSE publishes indicative noise levels for common construction equipment to help with initial screening.
Do subcontractors need to carry out their own noise monitoring?
Each employer is responsible for monitoring their own workers' noise exposure from the tasks they carry out. While a principal contractor may provide general site noise information, subcontractors whose workers use noisy equipment or work in noisy areas must carry out their own exposure monitoring and provide appropriate hearing protection.
