Floor Vibration
« on: August 21, 2011, 11:54:12 PM »
Hi,

I am living in the 3rd floor of an apartment. These days my downstairs neighbors uses ceiling fans, which cause the floor and my bed shaking during night. It is not noise, but can be more annoying. I talked to them and they won't do anything. So is there any solutions from my apartment? I put vibration isolator mounts under the bed feet, but they do not work well. Will it work to put a rug or some thing else under my bed? Thank you !

As a structure based vibration this will be a challenge. This vibration will be remitted through out the structure in the areas of least resistance.

You can put an underlayment and carpet wall to wall to get direct reduction, however the vibration will then be remitted from the walls.

What type of vibration pads did you use under the bed?

They are the so called "vibration isolator". Small round stuff. Does not work.

The vibration is weird, that I can only feel it in a pretty small area, perhaps less than one square meter. Only my body shakes, but not my bed (At least I cannot feel it when I touch it). I do not know what it is, hopefully it is not infrasonic. If it is not easy to isolate, is there any possible ways to monitor it? Thanks!

well its definitely not infrasonic cause the sound waves would be so large you wouldn't be able to get away from them in your home and if you can isolate it to one square meter then it most likely is your first idea of the ceiling fan....lets do a test...remove the vibration pads and replace them with wash cloths folded into quarters one under each leg. If you have wood floors, I also would like you to put folded towels or multiple blankets under the bed covering the whole floor under the bed. Let me know the results...what percentage of change is perceived.

Lets see if we can isolate it ourselves before jumping to expensive testing methods.

Cool! The wet clothes work! Thank you very much! The vibration has been reduced significantly. By the way, I am just curious, will only wet clothes work, or any other wet silk, cloth or fabric are good? And if I want to completely block the vibration, what else can I do? Many thanks, have a good one!

No no.. they are not supposed to be wet!....water helps transmit vibration...

Wash cloths... Dry Dry...
Use dry wash cloths and you will see more reduction...

Fix and re assess.

let me know.

Oh......that's why I feel better after a few hours. Will try it again. Have to wait until the downstairs turn on their fan...

Hi Randy, it looks like the dry clothes work better than towels. And it depends on the material, I think. A combination of towels and clothes will reduce about 30%-40% about the vibration. Although I can sleep now, but I definitely hope to reduce more. Is there any other effective way? How about a area rug covering the whole bed area?

Thank you very much!

Ok, since our little test yielded such good results you can order these products to improve the reduction even more.

This underlayment in a footprint larger than the bed.

then cover with area rug. followed by using these vibration pads under the legs of the bed.

Make sure your head board is not touching the wall.

Happy to be of service. :)

What about vibrations coming from a roof? :-( see my post: http://supersoundproofing.com/forum/index.php/topic,3612.0.html

Hello,

I just joined the forum because I'm having a similar issue to Ivan.  I moved in to a bottom floor apartment close to two months ago and have been trying to find a solution to a vibration in my floor which keeps me from sleeping.  I first noticed it as a humming sound in my pillow and that it is something coming through the floor.  I bought sorbothane pads to put under the legs of my bed, and it killed basically all the sound coming through and the vibrations in the bed, but it seems like the vibrations are still coming up through the floor and creating this uncomfortable feeling in the room. 

I've determined it's nothing in the apartment and it doesn't always happen.  I can happen every few days or so.  I've been looking into padding my floor with rubber flooring and then covering with thin carpet just to cover it up, and then I found this forum and wanted to ask.  Is the material that Randy mentioned below specifically for vibrations?  Will it work better than something like this? http://www.rubberflooringinc.com/rubber-roll/pre-cut-commercial-roll.html

Thanks so much!  I really hope I can get this sorted out soon and get some good rest again.

Andrew

That product you show is for vibration...when dealing with vibration into airborne sound which is what your experiencing then you would use the MLV closed cell foam wall to wall sealed airtight then your carpet.

Feel free to contact me direct anytime.

Hi Randy,

Thanks for the info.  Since I'm just renting and I doubt my landlord will approve of the work on the floor I will probably have to go with another option.  I will contact you soon to discuss! :)

Thanks so much,
Drew

Randy,

I came upon this thread and I am interested in pursuing the suggestions you mentioned in the previous comments. I will try using the rags this evening but can you please send me the updated links to the products you suggested to mitigate floor vibration? The old links are for mailordercentral not supersoundproofing
