Provider Factsheet 4 - Ambient Noise Level Testing and Equipment Calibration


Key Messages

  • Ambient noise level testing must be conducted at all sites every 3 years to the current Australian Standard (currently AS/NZ 1269.4 2014).
  • Audiometric equipment used for testing must be calibrated each year, to the Australian Standard/s relevant to each piece of equipment used.

Program Requirements

Ambient Noise Level testing

The Service Provider Contract 2018 – 2019 (Clause 10) requires sites to have appropriate equipment and facilities for providing services to clients. Providers are required to submit evidence on request. The annual Self Assessment Tool (SAT) questionnaire asks providers to certify that they have current ambient noise level certification for all sites.

All rooms used to provide hearing services to program clients must meet the relevant Australian Standard for Auditory Assessment (the Standard) (currently AS/NZ 1269.4 2014). Ambient noise testing must be completed for all sites every three years. Testing must be completed during normal business hours.

The Standard sets benchmarks for the measurement and testing of ambient noise levels and provides advice on procedures for conducting pure tone air conduction threshold audiometry. The Standard also sets out the conditions under which audiometry should be carried out and the form of the tests. These tests must be conducted at least once every three years and whenever a change in background noise levels is evident.

If you use an external contractor to certify your site, they must certify against the Standard. If you are performing the certification yourself, you will need to purchase the Standard to ensure you have the correct procedure, reporting methods and the calculation to determine the levels against which to measure. Please refer to the Standards Australia website

Certification should include the following details

  • name of the owner and address details of the room/booth undergoing testing
  • date, time and location that the measurements took place
  • octave band level measurements
  • headsets and enclosures used for audiometric testing at the site and if they are suitable to use with the measured background noise levels
  • equipment used to conduct testing and the date of last calibration or due date for the next calibration
  • the name and contact details of the technician/consultant who conducted the assessment.

Audiometric equipment calibration

All equipment used to conduct audiometric testing of program clients must be calibrated annually to Australian Standards.

The annual Self Assessment Tool (SAT) questionnaire asks providers to certify that they have current equipment calibration certification for all sites.

Certification should include

  • name and address of the owner
  • details of the equipment
  • the Standard/s under which the equipment was calibrated
  • the date the calibration was undertaken
  • the name  and contact details of the technician who conducted the testing.

Program Compliance

During compliance monitoring activities, including audits and the annual self-assessment, providers may be asked to provide Ambient Noise Level and Equipment Calibration Certificates.
