block of flats sound insulation?

[original flipper]

Hi

It sounds like you want to spend as little as possible - understandable in a rented property, so you probably don't want to make any major changes - correct?

I would suggest that you consider using furnishings, drapes and carpet as a way to soak up the hi-frequencies, to a degree (small) a lot of soft furnishing, particularly in corners will soak up a little of the bass feq's as well.

So a good heavy duty carpet - preferably sack back with a seperate heavy duty rubber underlay, some large heavy duty curtains/drapes over the window, maybe a second heavy duty wall mounted rug, drape or even carpet mounted on an opposite wall.

If you can stretch - it might be worth considering a double glazed window or even a fire check door - both to the room your going to do yourmusic in.

You could make a smallish floating floor by getting some heavy duty (rubber i think) slats from say studio spares lay a sheet of 8foot by 4foot by 3/4" thick plyboard on top and carpet on top the plyboard - this would not be too expensive - using all the things I have mentioned would probably make it possible to monitor at lowish levels through the night - at medium levels during the day without freakin any one out!

The box-in-box method is good, however for this to be effective you need to go air-tight (where there is air there is sound).

my band learned this the hard way in college. We built inner walls (with gypsum and wallboard layers attached to an aluminium frame) but did not raise the floor being on ground level we thought it would be OK - however we got complaints from a neighbor, and we realized the bass was literally carrying through the concrete in to her home! bummer.

Ahhh, good to know. Any solutions for such problems? I guess the glass-bubble would be the best solution. But you would need air-suply inside! But would be the bomb! You could put any sound at any level, no output.

Anyway, back to pratical. I guess a wall using bricks to make the box would be air-tight right?

I think you need to have special made walls to keep it air tight. Bricks most likely breath a lot of air through.
I'm not an expert though, just guessing really.

Yes, good point. You could use a paint (don't know the english name, used on boats) to make the bricks air-tight?

Lots of good info here

but the neighbour was complainig about the sound being transmitted through the aluminium frame to the concrete structure, not "airborne" noise.

Remember, air is the best insulation yet.

No its not. Actually it's the worst insulator.

Sound travels through molecules hitting other molecules. That's why clear air is the worst because the molecules are the farthest away from eachother so sound has the least interference in a given lenth. For this reason you want to use the most dense materials possible for in between the two the rooms.

This is the guy you want to talk to;

Some confusion here I feel.

No actually i learned that in my physics class, but after posting it i realized what he was trying to say. He meant that concealed air is the best insulator,which is explaned here:

One other thing you could try is to speak to your immediate neighbours. Explain your problem and you might be able to come to some sort of compromise.

i.e. they might be out during the day or not mind you mixing tracks between 6 - 8 at night and at weekends.

Might be the cheapest solution in the long run.
