AC 6996 - Can we hear spirits & angels speak?

AC 6996 [2]
... a man cannot even hear the spirits who are with him speaking with one another; and if he heard, he could not perceive, because the speech of spirits is without human words, and is the universal speech of all languages. Moreover spirits cannot hear angels; and if they heard, they could not perceive, because the angelic speech is still more universal. Nay, the angels of the inmost heaven can be still less heard and perceived, because their speech is not a speech of ideas, but of affections which are of celestial love. Seeing that sense these kinds of speech are so far away from man that they cannot possibly be heard and perceived by him, what then, so to speak, must be the Divine speech, which is infinitely above all kinds of speech in the heavens! It is said "the Divine speech," but the Divine truth proceeding from the Divine Human of the Lord is meant.
