Well, I don't know where to start...
I'll try to keep this really short as best I can.
In the process of building my HT room, I'm at the point where the DD is all installed with GG in between.
Soffits are done with OSB, GG and DW. (after the walls were done)
I'm now finishing up my stage and riser, both filled with sand, and something happened that I noticed lately. ( I can hear what's happening outside my room)
Yesterday, especially, was a disappointment to say the least.
While working in my HT Room putting the 3rd layer of OSB on my Riser.
My wife upstairs was moving some chairs and I couldn't believe how I can hear it downstairs in my room. She then called out my name to tell me supper was ready...and I heard her!
I keep reading all these threads of how people can't hear anything upstairs or when upstairs you can't hear downstairs.
I guess what I noticed yesterday is WTF did I do wrong?
Why do I hear what's happening upstairs?
I did everything that you guys did!
My ceiling is decoupled with Whisper clips, hat channel, DD 5/8" and GG in between. After the first layer of DW, I put acoustical caulking EVERYWHERE.
I just don't get it
What am impressed about though, is how quiet it is in the room.
I played music in the room...(2 speakers and a single 12" sub on the sand filled riser and I can hear it upstairs. If I crank it pretty good (-25 volume on a HK7550HD) things shake a little upstairs.
This discourages me because I will be putting 4x 15" subs on the riser and have a feeling that it will sound too loud!
Really sorry about this rant but I'm soo discouraged especially being 6 months into this project.
any guidance, feedback, advice would be appreciated
