Workplace noise is more than just an annoyance—it can pose serious long-term risks to health and safety. In other words, the Control of Noise at Work Regulations 2005, enforced across the UK, were established to mitigate these risks by setting legally binding responsibilities for employers. To sum up, the regulations are designed to protect workers from excessive noise, these regulations ensure that employers assess and manage noise risks proactively.
Whether operating on a construction site, in a manufacturing facility, or in a bustling warehouse, understanding these regulations is essential. Above all, non-compliance could lead to enforcement action, litigation, and—more critically—irreversible hearing damage to employees.

Understanding the Purpose of the Regulations
The Control of Noise at Work Regulations 2005 were introduced under the Health and Safety at Work Act 1974. Therefore, they align with European Directive 2003/10/EC and apply to all workplaces in Great Britain.
Objectives of the Control of Noise at Work Regulations 2005
- Protect workers from hearing loss and tinnitus.
- Promote safe work practices in high-noise environments.
- Ensure employers assess noise risks and reduce exposure.
- Raise awareness and provide appropriate training.
- Set exposure thresholds to guide safe operational limits.
These objectives form the foundation of occupational health frameworks across noisy industries.
Key Legal Duties for Employers
Employers are legally required to:
- Assess risks, from noise exposure using competent persons or qualified professionals.
- Eliminate or reduce risks, through engineering controls or safe systems of work.
- Provide hearing protection, where necessary and ensure it is used correctly.
- Conduct health surveillance, such as hearing checks, particularly when action levels are exceeded.
- Inform and train employees, on noise risks and safe practices, with records retained for auditing purposes.
These duties must be regularly reviewed and updated based on changes in workplace layout, processes, or equipment.
Employers should also document all efforts to reduce noise risks to demonstrate due diligence in the event of enforcement or insurance scrutiny.
Noise Exposure Action Values and Limits
The regulations set out clear daily or weekly noise exposure limits, expressed in decibels (dB(A)):
Lower Exposure Action Value (LEAV)
- 80 dB(A) – Employers must provide information and training; hearing protection should be made available.
Upper Exposure Action Value (UEAV)
- 85 dB(A) – Employers must take action to reduce noise exposure and require employees to use hearing protection.
Exposure Limit Value (ELV)
- 87 dB(A) – Taking into account hearing protection, noise exposure must not exceed this level.
Peak Sound Pressure Limits
- 135 dB(C) (LEAV), 137 dB(C) (UEAV), and 140 dB(C) (ELV) apply to instantaneous exposure.
Failure to comply can result in enforcement action by the Health and Safety Executive (HSE), including improvement or prohibition notices and potential prosecution.
Industry-Specific Considerations of Noise at Work
Construction & Demolition
On-site workers are often exposed to impulsive noise sources, such as jackhammers, drills, and pile drivers. Therefore, acoustic shielding, rotating staff, and limiting time-on-tool are practical strategies. Certainly, the Construction (Design and Management) Regulations 2015 should be applied alongside noise regulations to ensure holistic risk management.
Manufacturing
In sectors like automotive and food processing, repetitive noise from automated lines is common. The implementation of acoustic hoods, vibration isolation mounts, and regular maintenance schedules can significantly reduce noise. Staff rotation and acoustic zoning are also effective strategies.
Entertainment & Hospitality
Exposure to amplified music in pubs, clubs, and live music venues requires specific attention. Above all, venues should develop a noise control policy, use limiters, and provide ear protection for staff. Another key point is that special guidance is available through the HSE’s Entertainment and Leisure Industry Guidance.

Assessing and Managing Noise Risks at Work
When to Carry Out a Noise Risk Assessment
An assessment is necessary when:
- Noise is intrusive for most of the working day.
- Workers use noisy powered tools or machinery.
- There is a need to raise one’s voice to communicate at 2m.
- Work occurs in environments with echoes or reverberation.
- Concerns are raised by staff or occupational health providers.
What a Risk Assessment Should Include
- Identification of noise sources and affected personnel.
- Measurement using dosimeters or sound level meters.
- Evaluation against exposure action values and peak pressures.
- Recording of findings and controls.
- Review procedures in line with changes or after incidents.
Competent acoustic consultants, like those at Polaris Acoustics, offer comprehensive workplace noise surveys.
Noise Control Measures and Hierarchy of Risk Reduction at Work
Employers must follow the hierarchy of controls, prioritising solutions that reduce risk at source:
- Eliminate, the noise entirely, where possible.
- Substitute, noisy equipment or processes with quieter alternatives.
- Engineer controls, including enclosures, silencers, or barriers.
- Administrative controls, such as shift patterns, signage, and restricted zones.
- PPE, such as Class A/B ear defenders, should only be relied on when other methods are insufficient.
Practical Examples
- Enclosing compressors in acoustic enclosures reduced average exposure by 10 dB(A) in one aerospace facility.
- Switching from pneumatic to hydraulic tools in utilities maintenance reduced both noise and hand-arm vibration risks.
Health Surveillance Requirements for the Control of Noise at Work
Health surveillance is a key preventative measure under the regulations.
What Health Surveillance Involves
- Baseline hearing tests to identify pre-existing conditions.
- Annual audiometric tests to track hearing over time.
- Feedback and follow-up actions, including referral to occupational health specialists.
Employers must retain records and ensure staff understand the purpose of surveillance. Therefore, confidentiality must be maintained throughout.
Training and Communication
In accordance with the Control of Noise at Work Regulations 2005. Accordingly, clear, accessible training must be provided to:
- Explain the risks of noise exposure.
- Demonstrate correct fitting and maintenance of hearing protection.
- Encourage proactive reporting of concerns.
- Empower supervisors to enforce protective measures.
Training Delivery Methods for the Control of Noise at Work Regulations 2005
- Toolbox talks
- Onboarding sessions
- Online modules
- Refresher workshops
Training effectiveness should be evaluated through feedback forms or simple knowledge assessments.
Penalties for Non-Compliance with the Control of Noise at Work Regulations 2005
Employers who fail to meet the requirements risk:
- Improvement or prohibition notices.
- Fines and criminal prosecution.
- Compensation claims from affected employees.
- Increased insurance premiums.
- Damaged reputation among clients and stakeholders.
The Sentencing Council Guidelines emphasise the gravity of breaches in health and safety duties, often resulting in six-figure fines for larger organisations.
FAQs: Control of Noise at Work Regulations 2005
What if an employee refuses to wear hearing protection?
Employers must enforce PPE policies as part of disciplinary procedures. Therefore, alternatives or adjustments may be needed in cases involving medical conditions.
Do the Control of Noise at Work Regulations 2005 regulations apply to home workers?
Yes, if they use tools or equipment that expose them to hazardous noise levels. At this time, risk assessments should be extended to these environments.
Can smartphone apps be used for noise measurements?
Not for regulatory compliance. Only professionally calibrated equipment can deliver reliable readings under BS EN 61672 standards.
How often should noise assessments be reviewed?
At least every two years, or sooner if there are significant changes in equipment, layout, or work practices.

Final Thoughts on the Control of Noise at Work Regulations 2005
Noise risks are often underestimated until damage has already occurred. The Control of Noise at Work Regulations 2005 provide a clear legal framework to protect both employees and organisations. Above all, employers who take proactive steps—from proper assessments to robust training—create safer, healthier workplaces.
Auditing and revisiting noise management systems ensures long-term compliance. Evidently, involving staff, measuring outcomes, and consulting with qualified acoustic professionals are key components of an effective strategy.
