Above a metalworks shop
« on: April 14, 2010, 08:02:52 PM »
Below my offices is a metalworks shop. When they drill it gets very loud in our offices and it is very annoying for people who are on conference calls with us. They do some hammering, but it's mostly drilling.
The building is very old. The floor is wood (which we covered with carpet), the outer walls are exposed brick. What can we do?
Will pulling up the carpet and adding soundproofing below work? Should I cover the brick wall? What material should I use?

Yes, you could use our MLV w/closed cell foam underlayment for beneath the carpet.
The first thing you want to do is inspect how the drill is set up down stairs, if you can decouple the drill from the floor this will be the greatest reduction throughout the building. Then I would address under the carpet, finally after these 2 steps are finished then I would assess the brick walls if needed.
If the ceiling below is exposed joist then you will not get the same reduction value from our underlayment so this would be need to be looked at prior to purchase in order to evaluate the cost vs. reduction factor.

Thank you. It is exposed Joist downstairs. Would the MLV w/closed cell foam underlayment be pretty ineffective? Unfortunately we can't do much about what they do downstairs.

Ineffective NO, but definitely not full performance. Soundproofing from the source is the best reduction value, soundproofing from the receiving side allows the sound to stay longer in the open ceiling and allow more vibration into the structure before being reflected which would dictate a higher flanking value in the office above. The underlayment will still give you some reduction but most likely you will have to address the walls as well.
I would at least see if the business downstairs would entertain the option of closing the ceiling or adding some foam mat to the underside of the substraite. This would be a big help in getting a higher reduction.
