Tips on noise insulating 1880s old Victorian with Douglass Fir floors
OlofH

Hi,
I want to insulate the first floor from both impact sound and air borne noise coming from the second floor.
Are the solutions like putting acoustic mat and acoustic underlayment on top of old Doug fir and under new hardwood floor as good as opening the drywall ceiling from below and putting acoustic quilt and furring channels for new drywall?
I would like to avoid opening up the ceiling to put in quilt like Roxul SAFE'n'SOUND insulation if possible.
Thanks for any tips and advice.

You could cut holes in your ceiling and rent a machine to blow in cellulose or fiberglass. Cellulose has a much higher sound insulation value then fiberglass. Additionally you would go over the existing ceiling drywall or plaster with sound insulating drywall. It is expensive - about four times the price of regular drywall but very effective.
