Description
This unit of competency covers the ability to monitor noise using handheld sound level meters and fixed noise monitoring stations with either data logging or telemetry. It includes the ability to perform noise surveys, process data and report results in accordance with workplace standards.This unit of competency is applicable to environmental technicians in a range of industry sectors, such as environmental services (e.g. monitoring of environmental and/or occupational noise); environmental compliance, auditing and inspection; environmental management; and occupational hygiene.While no specific licensing or certification requirements apply to this unit at the time of publication, environmental monitoring and management activities are governed by relevant legislation, regulations and/or external accreditation requirements. Local requirements should be checked.
Notes
Elements and Performance Criteria
1 Confirm noise monitoring requirements
  • 1.1 Confirm the purpose for noise monitoring with supervisor.
  • 1.2 Confirm locations, timing and frequency of monitoring from workplace or client’s monitoring plan or other instructions.
  • 1.3 Check that all noise measurement procedures are in accordance with client or workplace requirements, relevant standards and codes.
2 Prepare for noise measurement
  • 2.1 Identify site hazards and review workplace safety procedures.
  • 2.2 Liaise with relevant personnel to arrange site access and obtain all clearances and/or permits, as necessary.
  • 2.3 Select noise monitoring instruments and any ancillary equipment that are required for the particular task.
  • 2.4 Assemble all field test equipment and complete all pre-use and calibration checks in accordance with workplace procedures and manufacturer instructions.
  • 2.5 Stow all equipment for safe and secure transport.
  • 2.6 Arrange suitable transport to, from and around site, as required.
3 Perform noise measurement
  • 3.1 Record significant site features, such as noise sources, their direction and approximate distance, relevant barriers, structures, noise sensitive areas and adjacent land uses.
  • 3.2 Select and record sampling sites and ensure that site conditions are conducive for valid and reliable noise measurement.
  • 3.3 Measure and record relevant site condition parameters and make any modifications to procedures, as appropriate.
  • 3.4 Check calibration of sound level meter, make any required adjustments and record results.
  • 3.5 Conduct noise measurements in accordance with workplace, regulatory and manufacturer procedures.
  • 3.6 Ensure that background measurements are obtained at an appropriate time, under appropriate conditions and in accordance with workplace/regulatory procedures.
  • 3.7 Repeat and record calibration measurements at the conclusion of the measurement sequence in accordance with workplace/regulatory procedures.
  • 3.8 Collect and/or record all results and ensure that they are accurately transferred to workplace information database.
4 Process and interpret noise data
  • 4.1 Review test data noting atypical observations.
  • 4.2 Manipulate raw data to obtain corrected and adjusted data and ensure that calculated values are consistent with expectations.
  • 4.3 Estimate and document uncertainty of measurement in accordance with workplace procedures, if required.
  • 4.4 Interpret trends in data and/or results and report out-of-specification or atypical results promptly to appropriate personnel.
  • 4.5 Determine if obvious procedure or equipment problems have led to atypical data or results.
  • 4.6 Compare results with established noise standards, statutory noise limits or similar, if relevant.
  • 4.7 Record and report data and results in accordance with workplace requirement.
5 Maintain a safe work environment
  • 5.1 Use established safe work practices and personal protective equipment (PPE) to ensure personal safety and that of other personnel.
