the quiet hum of chaos beneath which nothing, no matter how hard you shout, can be heard.
means the baseline level of random background interference in a system, below which a signal becomes indistinguishable from static.
from from analog electronics and acoustics, where engineers measuring signals realized every system, wire, and room has an irreducible hiss of thermal and electronic noise it can never fully escape.
