Workplace Noise Monitoring

Noise Monitoring (Static & Personal)

Noise monitoring is conducted to determine the level of exposure to harmful noise through the use of machines and equipment. The need for noise measurement and controls may have originated from previous audits conducted in the workplace, statutory compliance or redevelopment of noise management plans. Surveys are conducted to:

  • Identify items of equipment and operations which have the potential to cause the exposure standard to be exceeded;
  • Delineate all areas where the average sound level 85dB or the peak noise level exceeds 140 dB
  • Evaluate noise exposures (LAeq,8hr) so that personnel exposed above the exposure standard can be identified; and
  • Assess the adequacy of the noise reduction afforded by personal hearing protectors already in use and of alternative protectors if required.

We can conduct workplace Noise Monitoring using the following 2 methods

  • Sound Level Meter
  • Personal Noise Dosimeters

Onsite Audiometric Assessments

Based in Sydney, Trinitas Group have two mobile hearing test units that can come to your site seven days a week, 24 hours a day. We have a team of qualified Occupational Hygienists (trained against AS/NZS 1269.4:2005 Occupational Noise Management Part 4: Auditory Assessment) who are able to conduct testing across shift lines in the one day. The 2011 WHS Regulations state that:

  • Audiometric testing is required when workers are frequently required to wear Personal Protective Equipment to protect from hearing loss.
  • Workplace audiometric testing is required every 2 years.
  • New employees must be tested within 3 months of commencing employment
  • These workers include plant operators, production line workers, users of noisy power tools, truck drivers, call centre operators, nightclub staff, emergency services workers etc.

We will come to your workplace with our soundproof booth, alleviating the need to send employees off-site, saving considerable costs in time and travel arrangements. We will work with you to help scheduling staff testing and offer a full record management service and recall facility. We’ll record your last round of tests in our database for reference at no additional charge.
