Well, compared to a cockatoo, or macaw, they aren't loud, lol! My amazon can be louder as well. The difference is that many of the larger birds only make loud noise once or twice a day. Conures make quite a bit of noise throughout the day.
My Nanday is very vocal. Not all of it is annoying though. Her alarm screech is the worst. But, if people aren't coming over, I don't hear it much. When people first come over though she is quite a racket. My friends and family think that is all she does all day and don't know how I can stand it. No one believes me when I say she is mostly pretty quiet. She also contact calls, but I taught her to say "Hey, hey" instead. And she has this sound that is pretty loud that sounds like "Uh oh! Uh oh!" But, I actually like that one.
My BC didn't screech very much. Once she learned to talk, she talked all day. She would give an alarm screech if she saw a cat or dog she wasn't familiar with. But, it was quieter I'd say than my Nanday's alarm screech. Also, at least once a day she would yell out, "EEE EEE EEE" for a few minutes and it was high pitched and piercing. My cat hated it. The cat would run over to her cage and glare at her like, "If you don't stop, I"m going to eat you." She would stop, lol!
I would listen to the sounds of different conures and see what you think you could deal with. In some ways I find the Nanday's screech less painful because it's a lower pitch. But, on the other hand, the BC didn't do it as often.
