anūma
I think I figured out my dilemma from yesterday. I think jaxīra is the most basic word for sound or noise and jasāora is a more specific word for sound or noise made by an animate being. This distinction of animate vs non-animate is a theme of Kēlen, so that works.
On to today’s word. anūma is an attribute of sound, meaning loud. It is sometimes glossed merely as noise, since in the inanimate singular, it would mean a loud noise.
ñi sāen matāra il jahōλen ānen ansōha ānen anūri jūma ēmma;
He fell for a long time with silence except for the noise of the air.
