Building Your Noise Control RFQ (Request for Quote)

Read the article in PDF.

So you know all about the importance of mitigating noise pollution and protecting your employees and neighbours from harmful noise emissions. You did your homework. You’ve already read up on noise—you understand the safety aspects, the nature and behaviour of sound, and how noise control applies to your specific industry. Perhaps you’ve already incorporated noise control into your plans for your new or existing facility. Where do you go from here?

The first step in initiating a comprehensive noise control plan is to ask your friendly neighbourhood acoustical technicians to provide you with a quote for their services. In business jargon, this is known as an RFQ, or Request for Quote. Seems simple enough, doesn’t it? You locate a reputable acoustical engineering firm capable of meeting the needs of your project and see what they can offer you.

Proactive Noise Control – Planning a Facility with Noise In Mind

Download the article in PDF.

Hindsight is 20-20, even when it comes to noise control. Older facilities may be limited in their ability to accommodate the most efficient noise control solutions, sometimes requiring costly retrofits in order to meet noise regulations. However, if you are still in the planning phase of a new facility, now is the ideal time to take the noise impact into consideration. Doing so as early as possible will allow you to maximize the value of your noise control investment and minimize risk of noise complaints.

Applications and Limitations of Acoustical Walls

Download this article in PDF.

Though acoustical walls do have their applications as noise control measures, these applications are limited by the nature and behaviour of sound itself. While acoustical walls can be engineered using materials that absorb noise to minimize the reflection of sound off the barrier, sound can still diffract, traveling over and around the wall. Placing an acoustical wall on one side of a noise source mitigates noise in the space directly adjacent to the wall, opposite the sound source, known as the wall’s sound shadow. The only significant sound attenuation an acoustical wall can perform is found within this sound shadow created by the wall. If the receiver point or affected residence falls outside of the sound shadow, a wall provides little to no attenuation value.
