When I saw the title of the thread I remembered that there had been complaints from residents about the pitch and volume of the Tutor when operating at high RPM. I guess that any noise outside the aircraft will also affect those inside it.
Living near the secret Oxon heli-base I hear it quite often, but I don't complain at anything that gets youngsters/undergrads into the air.
