Flanking through Ducts

Common Workplace Noise Challenge: Flanking Sound via Ventilation Systems

For optimal workplace acoustics, poor planning before the construction phase can often be a major culprit. Addressing the issue of sound transmission through ventilation ducts at the early stages of design is a pivotal step in crafting a balanced and highly productive workspace.

Imagine investing substantial resources and time in constructing soundproof walls with a high sound reduction index, only to find their effectiveness compromised by sound traveling through the ventilation and duct system, resulting in a disappointing sound reduction index.

It’s can be an expensive mistake!.

Flanking through hollow core slabs.

Here’s another common and potentially critical Sound Flanking Transmission path!

Hollow core slabs can serve as potential pathways for horizontal sound transmission within buildings.

Sound can sometimes easily propagate through the hollow cores, leading to unwanted noise disturbances horizontally.

This phenomenon can pose a challenge in maintaining optimal acoustic conditions within our buildings.

Fortunately, if this turns out to be an issue, there are ways to combat this. By strategically filling specific portions of the hollow cores with high-density concrete, we can effectively impede the transmission path and minimize the impact of airborne sound flanking.
