NOISE MONITORING M A P P I N G ENVIRONMENTAL MONITORING Limitations on the level of noise that is allowed from industrial and mining operations is regulated to prevent damage and disturbance to those who may be affected. Noise monitoring is therefore a normal part of many environmental monitoring programs. INTRO


To help our clients meet their regulatory and safety obligations, 4T Consultants provides noise monitoring and analysis services and equipment for all situations, including agricultural, industrial, mining and urban locations. We provide both attended and non-attended monitoring and have a range of handheld and automated equipment for short term or continuous monitoring.

4T has partnered with specialists to provide detailed modelling, analysis and reporting.  This partnership provides clients with a site specific, yet cost effective service.

All 4T field staff are trained and competent and all monitoring complies with relevant State and National Standards.

Practical Application


  • Basic noise level checks, or spot checks
  • Longer term noise monitoring for compliance with regulatory obligations such as Environmental Authorities or Local Government regulations.
  • Predictive modelling in the approvals process for major projects.  
  • Noise and vibration monitoring for blast management on mine sites
  • Noise control investigations.

4T’s noise monitoring experience includes agricultural facilities and machinery, mining sites, residential, construction and industrial sites and factories.  So whether it is a one-off assessment in a workplace or longer term real time monitoring that is needed, we will work to find the most suitable solution and program.

For environmental noise measurement we use one-third octave measuring equipment, and the filters conform to the requirements of Australian Standard AS/NZS 4476:1997 Acoustics — Octave-band and fractional-octave-band-filters.
