Method of assessment

The following assessment methods are suggested:

  • review of noise data files, results and records verified by the candidate
  • feedback from managers and site personnel regarding the candidate’s ability to safely coordinate day-to-day noise monitoring activities
  • review of reports and recommended improvements to noise monitoring or noise control/reduction prepared by the candidate
  • questions to assess understanding of procedures governing the validation of data; acceptability of data/results; sources of noise data variability, interferences and uncertainty; and relevant preventative or corrective actions
  • analysis of case studies/reports of relevant noise management issues and incidents
