Sound treating an office next to a gym? (with more complications)

[Glenn Kuras]

There is nothing you can hang on the wall in your office that is going to stop the sound from coming in. The only way to stop (or reduce it) is with construction of the walls. I have a feeling that is out of the question.

Thanks for the prompt answer Glenn. That's the answer I was afraid to hear. Is there a way to keep the sound from coming in through the glass? It seems like a lot of the sound is coming in through tiny gaps where the glass was installed.

OR

Can the gym be acoustically treated to trap and keep some of the noise in the gym before it escapes into my office?

I priced Tectum acoustical panels for a small basketball gym earlier this year. The price of the panels and owens corning 703 insulation behind them worked out to $4.57 per square foot of acoustical panel. The cost was going to be several thousand dollars just to reduce the reverberation time in the gym-not to make it dead quiet.

And just to note that really would have not done anything to stop sound from getting into the office. You could put panels all over the glass wall and it might help a bit.

You could do a couple of things that would lower the sound entering your office...... to what degree is difficult (at best) to determine seeing as I can't physically examine the site.

That being said - a good set of door seals along with a drop sweep for the bottom on the door would do wonders.

You could add an additional panel of glass inside of the existing panel - picture a 3/8" panel of laminated glass....... the greater the size of the air gap the greater the level of isolation.

If the window is a typical steel frame it should be relatively easy for a glass company to provide and install additional stops and this glass.

Also make certain that the existing glass is properly sealed and does not vibrate - I've seen a lot of "dry set" glass installed in these types of frames that have a slight rattle due to the lack of a flexible seal between the stop and the glazing.

Neither of these remedies would "break the bank" - but would stop a lot of the sound being transmitted through each source.

Most windows I have seen in a set up like that are made from metal or some kind of custom framing. Trying to add another piece of glass might end up costing more then the wall itself. Not saying you can't but just pointing it out.

Glenn,

Typical school windows are usually cold rolled steel frames - the applied stops are simply screwed through the body of the frame for attachment - adding 2 additional stops (with a piece of glazing between them) is actually a pretty simple task.

I've worked with these a lot over the years - and used to own a glass company - this is actually one of the easier ones to deal with.

I see you added to your post.. Good to know on adding to a window like that.
