Rate These Parrots From Quietest to Noisiest? And Parrot Noise Qs?

i ahve a sun conure and a blue crown conure, both VERY LOUD!!!! lol. i have heard a atoo scream and based on that alone, i wouldnt have one.i find them fascinating but way too loud for me. i have heard macaws scream as well, but they are (imo) not as loud as the 'toos. my sun conure has a very high pitch scream, my blue crown does too, but not quite as bad.
