Ask Lemmy
A Fediverse community for open-ended, thought provoking questions
Please don't post about US Politics.
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
Reminder: The terms of service apply here too.

Noise cancelling earbuds or similar do not protect your hearing.
They do not make a loud noise quiet. It does not matter if they are working or not. All they do is make noise seem quiet, you are still being exposed to the same level of noise.
Do you have sources backing your claim?
Here is one backing mine: https://hillhearbetter.com/do-noise-cancelling-headphones-protect-hearing/
From your source:
Yes, but you said "seem quiet". No. It actually cancels the sound waves. So if it's quiet, it's quiet. The pressure is a different problem.
