I have 2 Barred Rocks and they are only loud when they see me. When I spy on them and they don't know I am there- they hardly make a peep. I also have 2 Black Australorps and they make even less noise. Both are great egg laying breed and friendly. I would try the Australorps if I were you.
x2 I have 2 BAs too and agree - they are very quiet and good egg layers. They are also very docile and friendly.
