I'm also lucky i guess as i live in a victorian detached house, though strangely everywhere i have lived has been detached
I could play music day or night at any level that pleases me or makes me go deaf if i wanted. The bay window appears to be strangely filled in (for projector use as it's an AV room) & along with a double thickness brick wall not a lot of sound manages to escape
At ear splitting levels it can just about be heard at the front gate (12ft from the front door), as for the neighbours they'd never hear a thing
