Noise at Work

The Control of Noise at Work Regulations (2005) requires employers to prevent or reduce risks to health and safety from exposure to noise at work.  The regulations require employers to:

  • Assess the risks to employees from noise at work

  • Reduce the noise exposure that produces risks

  • Provide hearing protection if the noise exposure cannot be reduced enough by using other methods

  • Make sure the legal limits on noise exposure are not exceeded

  • Provide employees with information, instruction, and training

  • Carry out health surveillance where there is a risk to health

How we can help

Consultation with both Employers and Employees

Undertake on-site noise measurements

Advise on noise control measures for significant sources within the workplace

Provide advice and recommendations on suitable hearing protection options

Clear and Understandable Assessments

We offer tailored workplace noise assessments to evaluate the noise exposure of affected operating positions within your business premises.  Our workplace reports are designed to be understood quickly.

We report a simple breakdown of exposure values for each operator position, including the calculated noise levels, applicable time limits and any required control measures to comply with Health and Safety legislation.

Depending on the nature and size of your premises, our workplace noise assessments can be undertaken simply with hand-held sound level meters, or where the noise environment is more dynamic, a network of dosemeters worn by employees throughout the course of a working day.

Commercial and Industrial Noise

The introduction of noise sources from commercial or industrial activities close to residential dwellings will most likely require a noise assessment in accordance with BS 4142:2014, Methods for rating and assessing industrial and commercial sound.

The method described in the standard requires measurement of the existing background noise climate in order to quantify the relative impact of any new noise source, which is either measured or predicted.

Once the level of noise attributed to the new noise source is quantified, it may be subject to further penalties for character of noise (such as tonal or impulsive elements) in order to derive a ‘Rated’ noise level.

Finally, the Rated level of noise is compared to the background noise climate to determine the significance of any noise impact.

If the background noise level is found to be exceeded by a significant degree, mitigation and control measures are implemented in order to limit the impact to acceptable levels.

BS 4142:2014 Applications
  • Commercial and Industrial activities

  • Sound from fixed installations such as HVAC systems and mechanical plant

  • Sound from associated commercial activities such as the loading and unloading of goods and materials

  • Sound from mobile plant and vehicles that is an intrinsic part of the overall sound emanating from premises or processes, such as that from forklift trucks

  • New residential development in areas of existing commercial or industrial noise
