is it just me or someone else seeing a microphone remained one-inch apart from cast iron pipe but closely stick with rest of PVC pipes?
Yep, distance was not consistent between systems, much farther away on the cast iron compared to the other pipes
Excellent work 👏 I still have pvc, so what do I do?MLV maybe.
How loud is 3” pipe in the horizontal orientation. Should I avoid going under a master bedroom if possible?
I wonder what happens if I dense pack the stud bay with cellulose or roxul rock wool
why didn't you test system 15 pipe?
Fix the pipe to the wall on two places and here u go
I don't understand why after you cover a pipe with an insulation wrapping it becomes louder in DB's??? That just doesn't make any sense. They should all be less in DB's.
it depends on the frequency of the sound.
