Or indeed maybe they have already deafened themselves with their own screeches, which is part of the reason why they can and indeed do shout so loud. I would think there is adaptive benefit in a very social animal that screeches so loud at point blank range to their companions, to be very tolerant of such loud noises (i.e. partly deaf). I don't actually know. They certainly can hear their own noises but they probably have little if any need to be able to hear anything else, although they can, because they easily hear people.
Something a bit like Ritchie Blackmore and I believe Ozzy Osborne admitting to be hard of hearing (I know so of the former).
