"accordion / concertina playing and loud singing?"

1. Can a accordion or concertina really be louder than the typical television?

2. Loud singing? Who's singing loud? Loud singing is ugly. Work on singing well instead. Also, don't serve any liquor. It's amazing the way beer consumption and loudness go up together.

3. Check to see if the electrical outlets in your place are right behind the electrical outlets in their place. That is a cheap construction technique which allows sound from one home to go straight into in the other. If so, find out how to soundproof that one place.
