NRC and STC relationship
Hello friends,
Need your insights here:
- Materials or Assemblies with high NRC generally have a low STC. (coming from Ballast sample questions)
Why I'm confused with this statement! A higher NRC means the assembly absorbs more noise therefore is should transmit less sound which is lower STC. But then a wall with higher STC rating is better than a wall with lower STC rating in terms of sound transmission. I'm missing something here that I cannot figure that out!
