Ear to the Ground

Welcome to another edition of our series on Frequently Asked Questions about Noise, Vibration and Acoustics. In this series, we answer questions that we hear most often from clients or through inquiries at our website. And this edition's question is:  How can I improve the speech privacy of my closed offices or boardrooms?

Noise-induced hearing loss is a prevalent workplace injury in the modern industrial plant. Employers must manage workplace noise exposure. Doing so is complex – in terms of accurately assessing sound levels and noise exposure in the workplace, identifying and ranking the dominant noise sources to be targeted for mitigation, and finding practicable, effective, and affordable noise control solutions.

In January, 2007, the government of Ontario announced changes to the Occupational Health and Safety Act (R.R.O. 1990, Regulations 851 and 855), introducing stricter limits for noise exposure in the workplace. The Act affects all industrial and oil & gas workplaces in the Province and serves to reduce the risk of noise induced hearing loss (NIHL) for workers. At the same time, the tougher regulations places additional obligations on industrial employers and on the Engineers responsible for the work environment.
