Basement sound proofing game plan
« on: December 07, 2017, 03:49:22 AM »
I'm finishing my basement and want to reduce the foot fall and nosies from above.  I can hear complete conversations easily above. 

Here's my plan:

5/8 drywall between 16" OC joist cavities with green glue sandwiched up to the subfloor above. 
Q: How much of a difference would a second layer of 5/8 drywall and green glue make?   The drywall is only about $175 more but the green glue is another $500 so if the difference is slight, I'll skip the second layer.

R19 faced insulation throughout

1/2" channel screwed to every other joist (Q: can I do every 2 joists?)

Single layer drywall screwed to channel.  Q: since it's a single layer, does it make much of a difference if it's 1/2" or 5/8"?

Once all this is done, I'll evaluate the effectiveness and if it's still bad, I'll probably spring for another layer of drywall with green glue although I'm hoping it won't be necessary.

Thanks for your input!!
