What is Sound?
Sound is the name that we give acoustic energy, and while the study of acoustics is complex, conversations about it don’t have to be. Acoustic energy causes an object to vibrate, and when it does, it creates fluctuations in atmospheric pressure surrounding it—like a tuning fork. Atoms and molecules surrounding the object become excited […]
Transit centre project a reminder that roof screens are one part of a complete noise mitigation system
It’s easy to look at noise mitigation components in isolation. A silencer, an acoustic plenum or roof screens could all be regarded as a standalone solution to a sound emission problem. In some cases, they are. But mostly they’re critical parts of a wider noise control system. That’s especially true of roof screens, which are […]
What are CHP systems—and why do their excess noise emissions matter?
Combined heat and power (CHP) systems have long been utilized in manufacturing and institutional settings to provide a reliable, energy-efficient—and thus more environmentally-friendly—source of power for a facility. That includes both new-build and retrofit applications. Now, a growing number of educational, commercial and even residential complexes are turning to cogeneration systems to meet their needs […]
A Parklane case study: Mitigating VRF noise at a high-rise condo
As the densification of urban areas continues and North American cities grow skyward with the construction of ever-taller condominium towers, noise control is becoming an increasing concern. Sound emissions are especially problematic in settings where large towers abut low-rise residential units—which are often impacted by their soaring neighbours in various ways, including unwanted mechanical sound […]
