Sound-proofing and STC query.

dakan

Hi All

not really a DIY question but I can't find any info on this in relation to Ireland anywhere. It is about soundproofing or the lack of it in regards to the dividing wall between my apartment and nextdoor. I have found out that the sound-blocking quality of a wall is measured with a STC number (sound transmission class). Does anybody know if there are any building regulations as to what STC quality walls have to have? Anybody know how you would test for it?

Thanks to anyone who gets back with any info. It seems very hard to come by.

Thanks
Dakan.

Thats the sound building reg. Have a glance through it, it should help.

Walls are on page 8. But it may be measured in STC values, but the regs spec a min density that the wall need to be. Do you know the construction of the wall.

Hi Mellor

apologies for not replying and thanking you for finding that info sooner. The separating walls are concrete as far as I know.

Thanks again.
