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.
I’ve always considered whistling simply plain rude and shows that they have no class, especially after 2000
Yes, yes and yes!
