Now you can't even scale Mount Everest without a drone buzzing overhead

"No chance of any peace, not even at 8,900 metres"

No chance of any peace almost anywhere accessible. One of my hobbies is wildlife sound recording, but with the advent of electric cars a hitch has emerged and is getting ever more significant. Distant IC traffic presents a fairly stable low frequency noise almost entirely below about 120 Hz ( a mixture of tyre noise and engine noise) with very weak harmonics that can usually be masked. Distant electric vehicles present in addition to the low frequency tyre noise a quite broad band of harmonic rich noise in the 400-1200 Hz band - right in the middle of wanted natural sounds, so they're well nigh impossible to filter out in the absence of very sophisticated (and therefore expensive) tech.
