  • Soundproofing - anyone have any experience of and/or recommendations for soundproofing (some rooms of) a flat?

    I'll be heading over to the 'Leaving London' thread if I have to listen to my upstairs neighbour entertaining visitors many more times. We're in a Victorian house converted into two flats, and we're on the ground floor. Relations with the neighbour in question are civil enough that we might be able to talk about splitting cost/getting access to her floors as well as our ceilings.

    What I really want to know is how effective it is - lots of websites talk about a 25db reduction in noise levels or whatever, but I have no idea what effect this will have in practice on your average headboard-banging or fake orgasm noises. Any chance of a good night's sleep or do we need to start looking at estate agents/hitmen?

  • If you want to know whether a 25db reduction is enough, try these one evening and then decide if you want to splash the cash.

  • I think your biggest issue would be persuading a neighbour to let you lift their flooring. That's quite a messy job involving getting the entire floor cleared.

    I think you could possibly get away with a shallow false ceiling to provide some mass to damp the sound.

    In the same boat here, we have a stompy upstairs neighbour who likes to go to bed later than us, get up earlier and has a noisy French girlfriend. It's been driving us nuts and is actually pretty stressful - sleep deprivation is no fun (his bedroom is directly above ours).

    We had been considering decoupling the ceiling in our bedroom and fitting noise reducing insulation as we already have this at the back of the house and it does help, but having read up on the site @rive_gauche linked to it seems to make a lot more sense to fit soundproofing mat under the neighbour's bedroom carpet (fortunately he has bedroom carpet) as that site says that this will have much more effect on impact noise (footsteps etc.).

    I can confirm that where we already have the decoupled ceiling/insulation at the back it reduces acoustic noise (e.g. a radio playing) a lot but footsteps not so much.
