Hello,
The dedicated music room is upstairs on a suspended floor.
It’s been suggested that placing insulation between floor joists can/will drop the noise floor by 6db. To give an idea of current noise profile, in the still of the nite when HVAC is not running, my spl app reads 33db, but much higher when life is being lived below the room.
The cost of removing the subfloor, precludes the use of batts. However, I can use blow-in cellulose insulation. And, because the subfloor is made of 8’W pine deck boards with 1/3” gaps, I can see through to ensure proper fill.
If anyone reading this believes blow-in cellulose insulation will NOT provide a benefit, please let me know.
If anyone reading this believes blow-in insulation WILL be beneficial in this application, please continue reading. The questions below address two ways insulation might improve audio reproduction quality in my room. If there are other ways, I’m all ears.
Questions:
1. If dropping the noise floor is the singular benefit, how much of a drop is warranted to justify the job? And would you expect my plan to provide such a drop?
2. Currently, when soundwaves created by my speakers pass thru the floor they enter into a hollow air chamber made of wood and drywall (my floor, the joists and the first floor ceiling). It seems like it would resonate/reverberate and gosh knows what else in there.
QUESTION: Will filling the empty air chamber below my floor with blow-in insulation be beneficial to my room acoustics even if—hypothetically, it doesn’t drop the noise floor by blocking outside noises originating from the living space below?
Thank you

At least come back after you finish to let us know what happened.
