Workplace Noise Risk Assessments

// acoustics, noise & vibration

Workplace Noise

Exposure to high levels of noise in a workplace, either as a sudden impulse or continuously over a longer period of time can have negative physical and psychological effects on employees.

Excessive noise exposure can cause tinnitus, stress and permanent noise induced hearing loss, as well as interfering with workplace communication, which poses increased risks of accidents occurring. The negative effects resulting from excessive occupational noise exposure can inhibit an employee’s future career and lead to social isolation and a reduced quality of life.

To protect workers from excessive noise exposure in the workplace, legislation is in place. In Ireland, Chapter 1 of Part 5 of the Safety, Health and Welfare at Work (General Application) Regulations 2007 (S.I. No. 299 of 2007), as amended by the Safety, Health and Welfare at Work (General Application) (Amended) Regulations 2007 (S.I. No. 732 of 2007), sets down the minimum requirements for the protection of workers from the health risks associated with occupational noise exposure. In the UK, the requirements are governed by The Control of Noise at Work Regulations 2005. The legislation sets out action values and limit values for two noise measurement parameters:

  • Daily Noise Exposure Level – The average exposure level normalised to a nominal eight-hour day, expressed as LEX,8h in Ireland and LEP,d in the UK, dB(A).
  • Peak Sound Pressure Level – The maximum instantaneous value of the sound pressure measured using a peak detector, expressed as Ppeak in Ireland and LCPeak in the UK, dB(C).

Aeon Environmental have vast experience carrying out workplace noise risk assessments for clients in Ireland and the UK. Our consultants can develop a risk assessment and monitoring programme to suit any individual requirements. The assessment process is outlined below:

1. Initial Review

Firstly, we liaise with the client to review all noisy equipment on site, employee work patterns and existing control measures in place to identify those potentially at risk.

2. Monitoring Programme

Our qualified consultants can then carry out a site visit and tailored monitoring programme, taking noise measurements on-site with a hand-held sound level meter and/or using personal noise dosimeters. We use state of the art noise measurement equipment and can cater for measurements in ATEX rated areas and other sensitive areas, where required.

3. Exposure Levels

On completion of the monitoring programme, our consultants will calculate the noise exposure levels of each relevant employee and compare the findings to all relevant legislation and guidance.

4. Reporting & Consultancy

After assessing the risks of noise exposure, we will issue a comprehensive report detailing all findings and recommendations, including any required hearing protection and control measures. This will ensure that the legislation is being adhered to and that the hearing health of employees is adequately protected.

Where required, Aeon Environmental can incorporate using software to display the existing workplace sound environment graphically in a contoured map.

We can also develop noise reduction strategies and hearing conservation programmes, as well as providing ad hoc consultancy services relating to occupational noise.
