Soundproofing an existing wall with batt insulation
« on: July 20, 2013, 02:32:02 PM »
I live in a townhome and do not hear noise from my neighbors except for impact noise from their bathroom against my bedroom wall. The townhome was constructed with a 2x4 wall for each home, with the green firewall in between. The bathroom has a daul vanity with drawers and doors that when closed create a very loud impact noise. My neighbor gets up an hour or more before me for work every morning so I hear this impact noise for a twenty minute period and would like to try and do something to my walls to help reduce this noise from such a loud sound. Would adding batt insulation in the drywall work or will it still come through just as loud?

Batt insulation will only help with airborne sound not the impact of the cabinets or drawers.
The only way to reduce impact is to decouple from the structure.
If your neighbor is nice, I would advise you to get drawer bumpers for his drawers and cabinets.
Reduce the impact at the source will be cheaper and a far better result...if you have to address this from your side than it would require taking down your drywall and floating it on clip and channel.
