Reduce Sub Vibrations

I'm moing into a new house and whereas before i have had students either isde of me I now have residents on the side of my room, I'm looking for a way to reduce the vibrations travelling through the floor to them, and as I am a poor student I am looking to do this as cheaply as possible! The floor has a thin carpet overthe floor boards and I have done my best with the wall in order to stop sound crossing over that way (I have fitted a wall hanging as thick as a rug across the wall).
Any help how to self soundproof a room would be greatly appreciated,
safe

Even if you isolate the speakers very well, bass still travels through a structure very nicely thank you. In short; you're going to struggle. Sorry.
That said:
Concrete blocks and old mouse mats stacked alternately with a few extra mouse mats on top will provide *some* isolation, at leastin terms of physical coupling. Obviously the sound coming out of the speakers will still travel.
Bass waves will travel through the rug thingy as if it weren't there I'm afraid. Not a bad thing to have up as it will kill some reflections, but it's not doing anything for isolation.
Good luck...

rubber car mats are a cheap AV solution.... still going to get tons of sound pissing thru tho... the vibrations are the least of your worries tbh...

Dont even bother trying to do a DIY soundproof job mate, its a waste of time. All the talk about egg boxes and rugs attached to the wall is bollocks.
You would be better of getting a really good set of headphones tbh.

couldn't agree more.
previously: sennheiser eh2200 (discontinued i believe)
currently: beyerdynamics dt770 pro 250ohm (VERY pleased with these)

Well I have just seen acoustic foam tiles for £32 which should cover the wall adjacent to the neighbours. Is this stuff any good? I have a decent set of sennheiser headphone but I like to DJ. I am also thinking of placing my most pwerful speakers hanging off the neighbouring wall...would this be better as the sound would initially be travelling into my house

sorry if i am coming across as stupid!!

That acoustic foam will do nothing at low frequencies. Forget it.
In addition, low frequencies travel from the speakers omnidirectionally, so it won't make a huge difference to your neighbours which wall you put them on.

fighting a losing battle, is there anything i can do about the low frequencies? By the sounds of it i can do a bodge job myself and hope to have a little impact. Worse case scenario i just have to turn it down
You seem to be clued up Macc, is there anything else you could recommend?

you're going to want/need two sets of cans then.
headphones for dj'ing you want heavy and loud.
for studio you want them to be flat frequency response across as broad a range as possible (some go as wide as 10hz-25khz).
the sony mdr and pioneer dj series for example colour the sound way to much.
whereas the beyerdynamics dt series gives you the straight dope.
even the same manufacturer can have vastly different headphones for both purposes,
like the sennheiser hd 25 sp (30hz to 16khz) vs. the hd 380 pro (8hz to 27khz!)
most, not all, dj headphones do a lo-cut and hi-cut to focus on banging the rest into your ear as loudly as possible,
so you can get your cue point amidst distractions.

This basically.
You cant fight physics.

Move house
MASS is the key word, as in, big thick walls, concrete etc. Air gaps in double leaf walls and so on follow on from that, but it all means building work, basically. Isolation in an existing structure is pretty much entirely down to how that structure was built.
What sort of construction is it?

why do you want to do heavy sound proofing in the first place?
if your djing then turn it down, protect your ears
if your producing then turn it down, better mixes, protect your ears

Sorry bigman didn't realise by asking a question that qualifies for having a bigshot like you taking the piss?
