In the UK, protecting workers from the risks associated with excessive noise is not only important but also a legal obligation for employers. Noise at work can cause significant hearing damage, from temporary hearing loss to more serious long-term conditions such as tinnitus. The Control of Noise at Work Regulations 2005 set out clear guidelines on how to manage this risk, and noise assessments play a key role in compliance.

What is a Noise at Work Assessment?

A Noise at Work assessment is an evaluation of the levels of noise employees are exposed to during their workday. It helps determine if noise levels are above the action levels set by the legislation, and what measures need to be taken to protect employees’ hearing.

The action levels are as follows:

Lower exposure action level: daily or weekly average noise exposure of 80 dB(A), or a peak sound pressure of 135 dB(C).
Upper exposure action level: daily or weekly average noise exposure of 85 dB(A), or a peak sound pressure of 137 dB(C).
Exposure limit: no employee’s exposure should exceed a daily or weekly average of 87 dB(A).

How Often Do You Need to Perform a Noise at Work Assessment?

There is no hard and fast rule about how frequently noise assessments need to be carried out, but the key principle is regularity and necessity. Here are some general guidelines:

Initial Assessment
When starting a new business or introducing new processes, an initial noise risk assessment must be performed. This will establish the baseline for future checks and ensure compliance with the noise regulations from day one.
Changes in the Workplace
Any significant changes to equipment, work processes, or layout could alter noise levels. In these cases, a new noise assessment should be conducted. Examples include installing new machinery, altering production lines, or changing the acoustics of a workspace.
If Noise Levels are Borderline
If the initial assessment indicates that noise levels are close to or above the legal action levels, regular monitoring should be established. This could mean yearly assessments or even more frequent checks if the environment is particularly noise-sensitive.
Following Complaints or Concerns
If employees express concerns about noise levels, or if there are signs of hearing issues within the workforce, a reassessment should be carried out. Worker feedback is a crucial indicator that conditions may have changed.
Periodically
Even without any changes in operations or equipment, periodic noise assessments should be scheduled. Industry best practice suggests reviewing the situation every two to three years. This ensures that risks remain controlled and that no gradual changes have occurred without notice.

Why are Regular Noise Assessments Important?

Regular noise assessments are essential for maintaining a healthy working environment and avoiding legal risks. Failure to comply with the Control of Noise at Work Regulations 2005 can result in:

Fines or legal action: Non-compliance with noise regulations can lead to significant penalties, as well as compensation claims if workers suffer hearing damage.
Reputation damage: Organisations that fail to protect their employees may face reputational harm, affecting their ability to attract skilled workers or customers.
Health and safety risks: Prolonged exposure to high noise levels without proper controls can cause irreversible hearing damage, putting employees’ wellbeing at risk.

How to Stay Compliant

To ensure compliance with noise regulations, it’s important to have a robust process in place for monitoring and controlling workplace noise. This includes:

Regularly reviewing risk assessments
Providing suitable hearing protection where necessary
Implementing noise control measures, such as quiet machinery or acoustic barriers
Training employees on the risks of noise and how to protect themselves
