Some babies scream in very high pitched and often, I wonder how does it not affect their hearing ability?
Ps: yes I have that baby and my ears are exhausted.
In: Biology
How do we know they don’t?
Their screaming is not directed into their own ears which helps. Same reason we can listen to thunder all day, but can’t listen to headphones on high volume for too long. You could also bring evolution in on it and say that babies born that can make themselves deaf would have been weeded out long ago.
Voice is projected away from baby out of their mouths, like older humans.
Hearing damage is primarily caused by sound waves being sent directly towards the ears.
Indirect sound waves are much less harsh and “weaker” in energy which are affected by distance (sound wave scatter; dispersing of energy/angle of dispersement), amount of surface “bounces”, amount of energy absorbed by surfaces and materials per bounce, the humidity of the air, and other smaller factors.
Scream at the sky and then scream directly into a mirror about one inch away from it. Your ears won’t hurt screaming at the sky but you’ll feel it screaming in the mirror. This might help answers your question
