Sound Dampening from Loose Insulation
Sound Dampening from Loose Insulation
(OP)
What would be the relative noise reduction from filling the space between a ceiling and first floor between the I-joists with blown in loose insulation? What would be the practical design considered as most effective? Considering costs? Is there a a type of insulation one needs to install by blowing in? Trying to reduce the sound in the lower level of a residential home from the 1st floor noise by filling the space between the I-joists with insulation. Thanks much!

In our house I used the resilient metal channels (Z shaped or mesh sided) sold by the gypsum companies, no insulation, and the upstairs bedrooms are carpeted. Pretty good for privacy and TV, although in a rental property I might do more. Gotta provide short drywall screws to prevent short-circuiting the resilient channel.
