ok im opening pandoras box here.(treatment vs framed wall art)


So i am in a dedicated 2:1 room and am treating it for sound ,it is very bright. Although I enjoy having a selection of framed pictures on my wall they vibrate and ring.I see so many unreal setups in the forum with a ton of pics on the walls. How are you mellowing the room down with 15 glass framed pics on your wall? .I realize its a battle between form and function but ...
Thanks

Geoff i hear ya . But what is the frequency they are vibrating at ? Above our hearing ? When my pics vibrate its the frame ratting on the wall itself so say under 100hz ? But the glass itself i would think is just ringing at a high frequency (causing brightness i would think  ) I am just guessing . I still would like someone with the means to try some sr or simalar on the glass itself  . There was a system here that had maybe 40 pics on the walls ??? Thats so much glass , mostly just curious ..

Every object has it’s own resonant frequency. An object will resonant or ring (only) when excited by a mechanical or acoustic vibration of its resonant frequency. So, depending on the size and thickness of the glass, the the glass will ring when acoustic waves of the resonant frequency excite it - or vibrate along with the frame/picture. I also suspect the grip of the frame on the glass might damp the ringing. People sometimes assume tiny metal bowl acoustic resonators or ebony discs produce high frequency distortion (excess brightness) when they resonate but they actually don’t. That’s why I said it’s possible the glass in the frames is acting as an acoustic resonator but the pictures probably wouldn’t be located in the right places on the wall to provide the benefit since placement is key.

I have four framed glass enclosed water colors in the room and have no problem.  I have room treatments, panels, bass traps and tube traps in the room as well.  My system is full range down to about 25hz with the speakers and two subs.

When the speakers were spiked to the carpet over concrete floor I used to have a strong resonance at around 125-250hz that would vibrate the walls if played loud and with music that had a lot of content at that frequency.  Removing the spikes and replacing with Stillpoints eliminated that problem completely.  The Stillpoints do not puncture the carpet or pad.

I would suggest decoupling the speakers from the floor.  Townshend pods or podiums would be excellent if funds permit.  

Geoff,
    What your saying I believe is spot on ,but again wouldnt this type of set up (glass pics behind spkrs side walls etc ) greatly effect the sound in the room?
   rhlijazz,
  Thanks for the input, I would love to mess around with stillpoints under my adagios.But I must say it is a little above my means to drop 5 hundred each plus subs just for fun. They are spiked on carpet,I originally had them on the just there platforms .I added the spikes and my bass tightened up imo.

It seems to me it would be easy enough to find out by listening with and without the pics. Not sure the results are necessarily predictable, however.
