The NEIGHBOURS probably can hear you if you were singing loudly, but what does it matter? (Unless you were singing something by Justin Bieber or One Direction, in which case, I can understand your embarrassment!)

Years ago, we could hear our neighbour doing a Tarzan call..... we just thought it was funny!

just your voice singing will be ok, as long as you arnt singing along to loud music

Why don't you just ask them?

i live in a semi detached house( the one's where they are joined together ) and the walls are made of plaster board and brick I think? I was singning on the landing with all the windows and doors shut. it was quite loud could they hear me singing? I know it sounds silly but I mega eembarrased!!
