Occasionally at JTA Noise we carry out assessments where we find that the noise is well within occupational and environmental standards and even best practice and yet the problem remains in that the complainant continues to be aggravated by the offending noise.

Reports of live music dying in Melbourne and moving to Sydney with the consequent loss of a Melbourne signature music scene came to a head in Brunswick last year where a local councillor intervened in a VCAT hearing to save an iconic local live music venue (The Melbourne Age, November 2013).

In a recent traffic incident a driver was accused of travelling at 140 km per hour through the Burnley Tunnel in heavy traffic. When informed of the alleged offence, the incredulous driver immediately questioned the calibration of the offending instrument. After a lengthy court case the driver was found not guilty, not due to calibration error, but due to measurement error, a prescient reminder of the importance of both calibration and measurement technique to those of us who drive instruments for a living.

Audiometric (hearing) testing shows that we still have some way to go to defeat 'noise induced hearing loss' which progressively steals the ability to communicate and, if noise exposure continues unabated, eventually socially isolates its victims. New evidence shows that the use of personal MP3 players has opened another front for the development of this serious affliction in younger people.

Restaurants can be loud—very loud. In Victoria and NSW, 85 dBA is the end of the WorkCover safe limit at which workers can complete an eight-hour day without wearing ear protection. Compare this to loud, noisy restaurants where customers and staff are regularly exposed to levels above this limit.

The dynamic nature of construction sites adds to the challenge of meeting the Model Work Health and Safety Regulations and Code of Practice for Managing Noise and Preventing Hearing Loss at Work which have been adopted in most Australian jurisdictions.

The Model Regulations require employers or “persons conducting a business or undertaking” to meet the noise standard through a “hierarchy” of controls.
