I recall many years ago, carrying my baby daughter in a back pack holder. I wasn't into carry then as we didn't live where carry was allowed. Old!
But if I had to carry now with an baby, I thought of this concern:
First - better to be deaf than carried by 6 or your baby carried by 6? Got that out of the way.
However, should one worry about the effect of handgun levels of noise on baby ears? I didn't search the med lit databases for different vulnerability of young ears. I did read a study that loud noise levels can be detrimental to a fetus in a discussion of pregnant women going to the range. I might suspect an immature cochlea might be more prone to damage. Looking at handgun DB levels most of the center fire levels, they are pretty loud: https://earinc.com/gunfire-noise-level-reference-chart/
.25 ACP 155.0 dB
.32 LONG 152.4 dB
.32 ACP 153.5 dB
.380 157.7 dB
9mm 159.8 dB
.38 S&W 153.5 dB
.38 Spl 156.3 dB
.357 Mag 164.3 dB
.41 Mag 163.2 dB
.44 Spl 155.9 dB
.45 ACP 157.0 dB
.45 COLT 154.7 dB
Adults suffer damage from these levels, even a few unprotected exposures.
Now, I see that standard 22 LR comes in at 120 DB. That's less. One can even find quite CCI 22 LR at about 60 DB.
So is this a concern, might one carry a 22 LR - there are p-f level folks who would carry a 22 LR J. Read a column about carrying a G44 - more rounds, quicker reloads but I don't know if the quiet rounds would run one.
So is that a concern for new parents? Is 'stopping power' more important vs. the more like deterrent effect of showing the gun or putting some rounds in an opponent vs. going for the more, supposedly efficacious round?
If I was a new parent or transition to grandpa - hmmm? Not an audition guy, was visual neuroscience.
