You might consider trendy fads.
It sounds like you are talking about the sort of annoying business jargon that shows up in Buzzword Bingo games, except that it is not limited to CorpSpeak.
Soniferous is what you're looking for.
Soniferous: Producing or conducting sound.
Example: Soniferous marine animals — M-W
How I found it:
I combined soni and ferous to make an adjective:
Soni of sonication + (-iferous) → Soniferous.
Sonication is a noun which means relating to sound. It's derived from sonic.
Sonic is an adjective which means:
Denoting, relating to, or of the nature of sound or sound waves.
Example: The whales emit sonic pulse systems — Lexico
-Ferous is a suffix which is defined by Lexico as:
-ferous (also -iferous): Having, bearing, or containing (a specified thing)
Examples: Carboniferous, pestiferous.
Origin:
From French -fère or Latin -fer ‘producing’, from ferre ‘to bear’.
First I combined sono of sonography and some adjective forming suffixes like ful, ive, ic etc and googled them but did not find any useful results. But googled sonoferous, the second result was 'soniferous' so I then googled soniferous and found its definition.
Quote from IBT UK:
The most common sources of marine biological sounds are snapping shrimp snaps, sea urchin raspings and fish vocalisations. Snapping shrimp (family Alpheidae), are the most ubiquitous and noisy soniferous animals in coastal ecosystems.
