I live in a busy town and got peafowl over here. No one complained about their noises to me. I am also very sensitive to noises during sleep and its been a year and not yet woken by peacock noises once. I sleep right through them. Here they even scream more as they are startled by the routine noises of town like cars and bikes. Believe me some times people exaggerate when they speak of peacock noises. Poor peacocks are notorious for a crime they don't commit. I personally think there calls are mesmerising and enchanting. U have got nothing to worry about unless you yourself are super sensitive to noises or got some really rude neighbours.
