Noise-induced hearing loss is one of the most common and incurable, yet preventable, occupational diseases of the 21st century. Until recently, noise controls were not considered critical while equipment was being operated, machinery used and production underway. Consequently, occupational noise continues to be a major health hazard in many workplaces.
Vipac leads the way in designing and implementing noise controls to ensure workplaces operate within ‘acceptable’ noise levels and health risks are minimised, if not mitigated altogether.
Our acoustic engineering consultants possess extensive experience conducting basic and detailed measurements for the assessment of occupational noise. Our best practice methodologies follow the latest standards, guidelines, and industry standard processes which assist us in evaluating practical, suitable, and cost-effective noise control measures.
Measuring Occupational Noise
Using intrinsically safe noise dosimeters and Type 1 Sound Level Meters, we can provide the following aspects of occupational noise surveys:
- Noise Analysis, of complex environments with multiple noise sources.
- Noise Analysis of machinery noise and room acoustics.
- Noise Mapping; noise identification, distribution and ranking in frequency.
- Predictions of noise impact for on new workplaces or expansions
- Recommendations on the type of noise controls to be implemented.
Managing Occupational Noise
Vipac designs noise controls to minimise or eliminate excessive noise pollution and prevent noise-induced deafness. With the reduction of even a few decibels, the danger of occupational noise to hearing can be significantly reduced.
Our acoustic engineering specialists visit existing sites to reduce excessive noise exposure, by modifying or replacing equipment in existing workplaces. We can also incorporate noise reduction strategies into the design of a new workplace or production process.
Types of noise controls
Our experience with industrial noise control has helped many companies achieve excellent internal acoustic environments. Examples of effective noise controls Vipac can implement include:
- Adding sound barriers (e.g. sound walls or sound curtains), noise enclosures, vibration isolation mountings and silencers appropriate to the work environment
- Stiffening and fixing damping materials to panels and constrained layer applications to reduce vibration and noise impact of items during processing
- Constructing sound-reducing enclosures that fully shields a machine(s)
- Separating noisy areas and quiet areas by a sound-reducing partition
- Embedding sound-absorbing material on floors, ceiling and/or walls to reduce the sound level due to reverberation
- Designing and developing acoustic materials for use under extreme conditions (hot, cold, humid, contaminated, abrasive, chemically hostile environments)
- Detailed noise modelling and mapping, with clear interpretation of noise sources, noise measurements and recommendations.
- Assistance with preparation and review of noise management plans to prevent, protect and preserve hearing within the workplace.
- Provision of expert witness services, for Workers Compensation Claims for hearing loss and other health-related issues relating to occupational health and safety.
- Annual or biennial onsite noise impact assessments and review to attenuate any possible noise issues and legislative action, depending on industry area.
- Design of noise mitigation measures, including optimisation of noise barriers.
- Review of existing noise policies and procedures for your workplace, with assistance in modifying or creating where information is currently lacking.
- Review of existing hearing protection devices, and their effectiveness.
- Review of existing hearing protection signage.
- NATA accredited measurements and monitoring of occupational noise.
- A positive by-product of legislative compliance.
- Reduction in worker’s compensation claims and improvements in productivity and performance.
- Impartial advice and recommendations in mitigating excessive noise levels.
- Cost effective, when implementing noise controls into the design of a new workplace or production process.
