Dampening sound vibrations

Ginger

Right last few questions

I will be leaving over an apartment and we have wooden floors. The floor has been insulated to reduce the sound pass through. But if I have a sub woofer on the floor its gonna shake the people below me out of it (especially on rugby days :P )

Is there anything i can get that will dampen the sound so it wont travel down. I was thinking a piece of spare carpet but are there other solutions

Thanks

When it comes to lower frequencies, in my experience not really (at least not on the cheap.. ). I would be surprised if placing a carpet under the woofer made any difference (it would reduce high frequencies). So the cheapest quick fix to reduce the bass travelling downstairs would be to put the speaker on good spikes/cones. Less vibration will travel to the floor. It would help a bit anyway.

Oh, that and turning the volume down.

Bass frequencies are hard to sound proof against, because there is more energy involved in producing those frequencies (more air being pushed), and they pass well through most construction materials.

Thanks Dalk, now the question is, is where do I get the spikes for this sort of thing?

Dont know specifically. The usual suspects... hifi shops etc

The Sort of thing you are looking for, so you dont damage your wooden floor.

BTW i have also heard of some people putting their woofer on spikes, and then sitting that on a slab of concrete/slate/something hard. Claimed to help reduce sound downstairs...

Perhaps you could make some kind of plynth (sp?) to put it on? Perhaps a hardwood box on spikes filled with sand with sound deadening heavy tar paper ( as used in cars) or noise killer spray on the top and bottom.

I have read somewhere . . .

try to put the subwoofer into a slabs (get from DIY shop), most of them said it reduces vibrations.

A big blob of blu-tac under each corner on the sub will do the trick. (seriously)

I was thinking i might have actually found a use for the polystyrene packing in the boxes...

Just some packing material under the sub maybe that will knock it all out..
