From 1 January 2024 there will be changes regarding hearing tests for NSW workers. 

If your business requires workers to frequently use hearing protection as a control measure for noise that exceeds the exposure standard, you must provide hearing tests for workers. The person conducting a business or undertaking (PCBU) must organise and pay for the hearing test.

For new workers, a baseline hearing test must be completed within three months of commencing their employment. The worker must then get a follow-up monitoring hearing test at least every two years during their employment.

More frequent hearing tests may be required for workers exposed to high, average noise levels throughout their work shift, (e.g., ≥ 100dB(A)).
