If your child (or one in your care) complains about noises or sound, this is a quick summary of sound levels, sound frequencies and how it affects human health: https://decibelpro.app/blog/can-sound-kill-you/
As a note: 70dB to 85dB is a non-stop level in public spaces currently. A 2 hour movie can often reach 90 - 95 if not louder.
110-124dB is the level of new hand dryers in public loos.
Electric vehicles, scooters and LEDs resonate at a piercing high frequency: wear ear plugs and defenders when near the streets - you cannot get your hearing back!
Whistling enrages me. I feel bad about it because whistlers are usually just trying to express their good mood and share it with the world a little, but it hits my ears and brain in an extremely unpleasant, almost painful, way.
Yes, yes and yes!
