Now that you've learned about Optimized Acoustics, it's time to put it into use. We've taken the guesswork out of it with this handy infographic. Take a look at how to use Optimized Acoustics successfully in classrooms, open-plan offices and patient rooms. It's a great reference for your next project.
There’s good reason why acoustic requirements are becoming more stringent when it comes to designing and constructing public spaces.
Noisy environments affect:
- Student comprehension
- Office worker job satisfaction
- Patient recovery time
What is Optimized Acoustics?
It's using a ceiling system to optimize sound absorption (NRC) and, where needed, using walls or plenum barriers to block sound (STC). The result? Designs that comply with standards and achieve the best sound experience for the real world.
NRC – Noise Reduction Coefficient measures sound absorption
STC – Sound Transmission Class measures sound blocking
For classrooms, the Optimized Acoustic approach recommends:
- A sound absorption of NRC 0.80 or higher
- A sound blocking rating of STC 50 – use full-height walls to achieve this
Tip: ROCKFON® Koral™ stone wool ceiling tiles achieve NRC 0.85.
For open-plan offices, the Optimized Acoustic approach recommends:
- A sound absorption of NRC 0.90
- Blocking parameters like CAC and STC are irrelevant because there are no walls
Tip: ROCKFON Sonar® stone wool ceiling tiles achieve NRC 0.90 to 0.95. If suspended ceiling are not possible, consider overhead sound control like ROCKFON® Contour™ baffles or ROCKFON® Island™ solutions.
For patient rooms, the Optimized Acoustic approach recommends:
- A sound absorption rating of NRC 0.90 or higher
- A sound blocking rating of STC 45 – use full-height wall or lightweight plenum barriers to achieve this
Tip: ROCKFON® Medical™ Plus stone wool ceiling tiles are ideal for achieving an NRC of 0.90.
