Uhh huh huh… you said depth.

I think that’s the point of a rape whistle, people might ignore a call for help, but will instinctively look towards a shrill piercing whistle.

They might not help, but extra visibility might deter the attacker.

I’ll also toss A Way with Words on the pile too. It’s a long running NPR-adjacent radio show/podcast about linquistics.

My favorite was a dive they did on the descriptor “like a dead preacher” to refer to an annoying awkward thing to move.
