I would think there'd be a lot of utility in not blocking smoke alarm sounds, for example. The screeching from distressed infants can similarly be both very loud and very high pitched.

Infants scream at the resonant frequency of the human ear canal, about 3000 hz
I'm trying to search this and it seems the numbers for both (ear canal and infants cries) are all over the place. Do you have a specific article about the connection?
Interesting if true...
I was once interested in music production, and I heard a tip to cut a notch in that frequency range to reduce perceived harshness that is speculated to be due to our sensitivity to infant cries. I can't help with a source but maybe that angle might yield something.
