Hi Momo, how's your singing voice. When my three make more noise then I want listen to, I sing to them or just talk. They always stop making their noises to listen to me. Just try to nip it in the bud and make some other noises, sounds more pleasant than what your grey/tiel is doing. Also if the noise is too much, pull the drapes and turn off the lights so that it is darker in the room that perhaps will also quiet down your parrot. The problem is what most of us do when we first get our grey, we are so pleased to finally have a grey that we over indulge with the petting and playing and carrying around and then when the grey is more common to us, we move on to other things. It confuses our spoiled greys/parrots and now it is up to us to turn them around to a more satisfactory relationship. But patient and try to make it easier on both of you.
