Question Should I mix accoustic insulation and normal insulation to absorb sound?

Hi,

I have bought some accoustic wool (60kg/sq m 100mm) and have started to fill the joists under my floor. The floor already has standard thermal insulation.

1. Is it worth me putting the standard wool on top or underneath the accoustic wool? Any advantage?

2. Can I cover all the cables with the accoustic wool and/or the standard wool?

I'm planning to put sound mats on top of the chip board floor in an attempt to stop sound travelling from a ground floor room into a bedroom and vice versa.

Hope someone can help me!

Thanks

AL

Re: Should I mix accoustic insulation and normal insulation to absorb sound?

Hi,

I've done a similar thing. My sons bedroom is right above the cinema room so I bought a load of wool and stuffed two layers between the joists. Then under his laminate floor I put some acoustic matting.

It does make a difference but tbh, you can feel the sub through the whole house when it's on anyway

I would imagine there'd be no problem laying the wool on top of the insulation.

Bob.

Did you fill the joists to the top? Or is it worth leaving some kind of gap so the insulation - accoustic or normal - doesn't touch the floorboard and 'transmit' sound???

I'm going to do a course in all of this stuff!!! Must be simple all of this??
