Noise exposure in industry is one of the main reasons for hearing loss. In
recent years, changing legislation regarding "acceptable" noise levels in the
workplace has been aimed at reducing the number of Workers Compensation Claims
for hearing loss. Control procedures can be implemented where potential hearing
risks are discovered either by in-house monitoring or by the evaluation of
experienced consultants. Vipac Engineers & Scientists have been offering
consultancy services in the areas of Occupational Noise and Industrial Acoustics
for nearly 30 years:
Noise Measurement - occupational noise exposure in accordance with the relevant statutory standards, machinery noise and room acoustic properties; sound intensity measurement for noise analysis in complex environments with many noise sources; preparation of noise contour maps with clear interpretation; detailed noise surveys, noise sources identification and ranking.
Noise Exposure Control - planning and design of future low noise
exposure working environments; predictions of noise impact from proposals,
for new workplaces or expansions.
Engineering Noise Control Methods - design of noise control
treatments, including change of process and machine components, use of
damping materials and constrained layer applications, design of barriers,
enclosures and silencers.
Testing and Development - testing of the acoustic performance of
materials; development and specification of acoustic materials for use under
severe conditions (hot, cold, humid, contaminated, abrasive, chemically hostile
environments).
Occupational Noise Management - feasibility studies; program
management; advice on selection of optimum hearing protection devices;
problem solving and educational services for staff and managers; provision of
expert witness at public hearings, planning tribunals.
