A unsilenced 9mm out of a handgun is normally around 160db (assuming common ammunition and a common type of handgun). A reduction to 125db with a silencer seems about right.
Edit: Here’s a silencer talk link that goes very in detail. For their chart, 125 db is actually very close to the low end, with many suppressed shots being louder.

FWIW I believe those measurements are right at the silencer while the thunder measurement I find is “within a few hundred feet”. There can be quite a significant drop in perceived noise from silenced guns with a moderate amount of distance making them sound like a distinct but not overly loud“thwack”.
A reduction of 35dB is more than eight times as quiet, and 3162 times less energetic.
A few decibels can make an immense difference because decibels follow a logrtihmic scale, and this is especially true at the noise levels of a gun. Don’t be fooled by the seemingly small reduction of even 20dB on an original measurement of 160dB; you’re reducing the amount of sound my much, much more than the ⅛ that you might expect!
Absolutely. To add perspective, typical firearm hearing protection reduces sound by 25-35dB.
I’m sure the full story is more complicated when taking into account frequencies, duration of the spike in sound, etc.
