False ceiling vibrating. Any solution please???

[Fiftyfifty]

False ceiling and wall paneling are fixed onto a framework; of galvanised steel in case of former and wood in case of the latter. Large panels vibrate especially when LF is generated; period. Generalist contractors, workers do not envisage the kind of SPL and frequency range that's generated by high fidelity sound systems and since a close grid framework means more money, make it only to provide optimal structural stability which is just not enough. It may or may not get solved by placement of speakers and Subwoofers. The proper way to solve would be to add reinforcement behind the vibrating panel. Quick fixes would include things like reducing the volume, adding some weight onto the vibrating panel etc.

Fully agree! This is the only real reason.

well agree with whats being said about a close grid framework, and this is at a planning stage when interiors are being designed. but since that stage has passed, whats the best way to deal with vibrations - I am not a sound engineer etc so scientific approaches to dealing with this problem and creating an acoustically treated room is not my forte.

I am sure there may be ways to atleast reduce these, carpets, curtains etc for reducing reflections etc are the poor mans quick fix is that the only way. a few other tips would help us lesser mortals atleast get rid of some nuisances as the goal is not to attain audiophile nirvana at this point but to remove distractions in what would spoil the whole experience of listening to music

The easiest solution I've found is to put foam plugs into the bass ports.

In my case it was the glass sliding window vibrating in deep bass. I replaced the stock rubber linings on the frame with felt ones and my vibration disappeared. Also helped in reducing ambient noise from a busy road substantially.

Hi all....
Even without a sub, there used to be vibrations earlier.
I moved the FS away from the front wall. Sound quality improved, and the vibrations are almost gone.

But when the sub is switched on, there is a lot of vibration. Filling that cavity, and closing it with a long strip of POP (false ceiling material) may solve my issue. But before that, I will try all other easy tips shared above...

Hi,
I have a similar problem and many others with false ceilings have it too. I hear the vibration only in one song at the strike of one bass note. Lower bass, higher bass do not cause the vibration. What I hear is actually a buzz. I don't think the problem can be solved by stuffing the opening on the side. It is more likely that the entire false ceiling, which is usually suspended, vibrates at a particular resonant frequency. It would be nice to hear from someone who has had this problem and solved it.
Cheers!

used to vibrate during-Shaan- of "Lata Mangeshkar,Tuzase naraj nahi jindagi pare"shan" hun main"
Borrowed a 15 steps equalizer.
Fed various frequencies from the frequency generator of my Samsung S6 edge.
Found out that my particular area vibrates at around 200 htz.
reduced 125 to 250 slider down to -12 db.
Vibrations reduced considerably.
My way to solve a problem.
waiting for 31 band parametric equalizer now.
