New Studio Build, Hello!

Hi Andy! Since that is a gas line made out of heavy galvanized steel I was not worried about sound traveling through it to the rest of the house. It is not like the other vents and HVAC stuff that I enclosed in that those other vents and ducts open up to every room in the house and would be piping audio from the studio to the every room in the house too if they were not soffited. Those soffits in the joist bays are double drywalled and filled with R19 and acoustically sealed, the penetrations where gas line runs through them have drywall attached to the outside and are acoustically caulked as well. Personally I would not spend the time or money to reroute any of your gas lines. I don't think any benefit would be worth the headache. Allen

So your gas line is not going to other levels of the house correct? In my case the gas line runs up into the kitchen upstairs which is what has me concerned.

Ya our gasline goes upstairs too. We have a gas fireplace but no issues with noise do to the gasline. It is such a small dense pipe vibrations don't carry through it. The only thing I would be worried about is sealing any penetrations where it is going through walls or between floors. Other than that I don't think you are going to get enough benefit/NR to justify the expense and time of moving them. Allen

Well fantastic! You've just saved me a whole lot of time, money and headache! sometimes it's great to get some real world data beyond the theory!
