Can i stop the BASS ..

[peder]

Hello there

we are a bunch of people sharing a big rented house where we have build studios (not particularly wee i might add)

well here's the problem..

i work on a lot of quiet tracks these days and my upstairs neighbours are currently working on "dubstep" .. in case you don't know what that is - its agressive fast garage like music but with a dub feel too it and its all in the bass..

needless to say i would love to have even less of their bass transported to me..
i think i can hear from sub 40/50 to around 100

my ceiling is lowered about 7-8 inches.. i have put rockwool there - it helped a little bit..
i have also given them some auralex foam to put their speakers on (didn't do much)

how about spikes for their speaker?

or is raising their floor the only thing to do????

thanks for all the info i get from you all

Even if you hang their speakers from springs suspended from the ceiling, bass will go through the air to the structure and then to you. Isolation at low frequencies is very difficult in a house. And very expensive. I know this is not what you want to hear, but it's reality.

Sure, that may not work, but the imagery is priceless.

Though Ethan is the bearer of bad news, he's absolutely right. More mass and decoupling is what's necessary to do what you want to do. That doesn't come cheap.

thanks for the bad news :)

so do you think raising their floor will do something or is it too much work for small results??

I wouldn't bother raising the floor. To do it right (such that "right" = "effective at low frequencies under 100Hz") you will need SERIOUS mass, such as a wood deck, several layers thick, with dry sand between the joists, floated on pucks that have been correctly calculated in terms of number and spacing. It is highly doubtful that the existing structure could bear this kind of weight load. Certainly, it will be essential to consult a structural engineer before attempting something like this.

And, given that this is a rental space I doubt it would be advisable anyway.

A better option, though still probably unrealistic since it's a rental, would be for you to build a room-within-a-room, with an isolated ceiling, in your space. Even this will only be realistic if you are on the ground floor on a concrete slab; even so it is a serious construction job that your landlord will need to sign off on.

Yea I am sure the landlord will not mind the new "ROOM IN SIDE OF A ROOM" look!!!! lol lol

allright thanks a lot guys..

you saved me a lot of trouble :)

hello there again ...

long story short

cause the lowered ceiling in my studio has small holes in which the rockwool/dust comes out (and lands on my head) i have decided to lower the ceiling again :)
it's by far the easiest thing to do - plus it will also take away a little of the noise from upstairs

hence my question..

anything i should take in to consideration when lowering the ceiling again in terms of noise reduction???

[jwl]

Noise reduction, especially at low frequencies, is about 3 things: mass, airtightness, and correct construction techniques. Insulation will help, but most of the help comes at higher frequencies.
