Noise enhanced in semi-closed space
« on: September 29, 2007, 05:16:23 AM »
I'd like to use the large space under my high-length bed as an on-floor reading space.

My problem is that the bed (that is just next the wall) is just across the window where traffic noise comes in (mostly the bassy part of it), and the bassy part seems to increase in effect under the bed (I can especially notice it when I put on a closed-headphone).

Maybe it is caused by the reflections from the wall or the sides. I don't know. Is there a way to reduce that bassy impact, by, maybe placing some noise-absorbing material on the floor, and three closed sides? And, I would be glad if you can suggest the types of material I can use for that (possibly stuff for everyday use, like carpets).

Thanks in advance...

Yeah, the bass is accentuated in corners.  Lots of 90 degree angles to reflect sound - sort of a 'focusing' effect.

I doubt carpet is going to do the trick.  You need foam absorbers.

Check out this page:

The products might be too expensive for your budget, but it'll point you in the right direction as to what you need. 

Also, check out this website (supersoundproofing.org) and search for foam pads/absorbers.  They'll probably have what you need.

You can absorb and block the sound right at the window before it gets into your room to reverberate around in all the corners.  Use the 2" thick closed cell vinile nitrile foam - it is the first product shown at http://www.soundproofing.org/sales/prices.html
And for info on how to do a window plug see option # 4 at http://www.soundproofing.org/options_sound_control_for_windows.htm
