Is there an adjective that begins with the prefix omni that means all-hearing? I thought that an aural counterpart to omnipresent, omnipotent, and omniscient must exist, but after a few minutes of Googling, I've failed to find any synonyms for all-hearing.
The logical construction would be along the lines of omnaudient (given the Latin verb "to listen" is "audio") but I've never seen it used.
Omniaural? (Maybe this just means, "can be heard everywhere".)
"Omniaudient" used in "Midnight's Children" Salman Rushdie 1981.
