There is no such thing as a Stupid Question!
Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.
- ex. How do I change oil
- ex. How to tie shoes
- ex. Can you cry underwater?
Reminder that the rules for lemmy.ca still apply!
Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice ๐.

it's worth keeping in mind that dB fall off very quickly over distance and having a jackhammer right up next to your ear is different from passing a few feet beside it
Yes that's why dB measurements are always done in open air from 1 meter distance.
edit: Headphone measurements are obviously different and are optimally measured at the distance the eardrum sits from the speaker element, with similar encasing as the headphone model offers. For In-ear, it's a very low distance and a high level of encasing. Airpods will obviously not make 105 dB at 1 meter.
The 105 decibels is the max headphone output as it's placed in the ear.
