Sound proofing between floors

pred02

I live in an upper flat of an Edwardian conversion apartment in South London. I have a problem with the downstairs neighbors complaining of noise when playing music on my stereo. I only use the system for audio, no HT and do not play excessively loud.

Irrespective of the issue, I am going to be restoring the old wood floor in my house. As such, the builder offered the option of adding insulation mineral wool (15mm) between the floor joists to increase noise protection. This would cost me about £600 and would be done as part of the process

How effective is this against reducing noise between floors?

I am sure a number of people live in period properties so any info on sound reduction is much appreciated.

Restoring the floor to use without carpets?. This will increase the noise transmission. Do you have carpet now?. Moving the speakers off the floor and on to wall brackets may help.

Today there is laminate that is going to be removed and the old wood floor will be restored. I am wondering if putting in 15mm insulation (mineral wool) between joists between my floor and one below will help reduce the noise.

Thanks

You will get more complaints not less, you really think 15mm of wool will block out more noise than the laminate!

You really need to consider underlay and carpet, that will be more affective.

You will never block out enough noise to please downstairs, without spending thousands, these types of properties are not made well for flats.

You need to do as much as you can i.e underlay and carpet, then be considerate, then if you still get complaints, it's not because you are noisy but because of the poor flat build, and your neigbours need to either learn to live with this fact or move.

check out soundstop.co.uk they have good advice. Realistically you need to isolate the floorboards from the joists, stick 100mm of acoustic rock wool (not the insulation type its too light) in between the joists, and then you need to seal the floor, and put a membrane over it.

Anything else is likely to be !!!!ing into the wind TBH!

Have you checked your lease? Are you allowed solid floors?

15mm ? of insulation wont make the least bit of difference

15 mm. Sounds like a figure plucked at random. It's not even as thick as the existing floor boards.
I read somewhere that some of the grand old mansions had thick layers of walnut shells in between the floors to deaden sound transference. Obviously not an option here.
