Hearing Protection

Personal protective equipment, such as hearing muffs and plugs, can be used to reduce workers' exposures to noise after engineering controls have been implemented. This video examines the benefits and limitations of hearing protectors in work environments.

Very clear and to the point; great work!
This should be mandatory knowledge in any work environment.

[@JohnAlexanderBerry]

Well explained. I found that my earmuffs provide the best sound reduction (and are easier to use than ear plugs)!

[@James28R]

well clearly if you cant put them in properly then that will be the case

[@happycamper6352]

Finding good quality information on this subject in video form is difficult, but this video was helpful. I didn't know that pulling the ear back before inserting helps, but now that I tried it, I'm thankful, because it really does help. I was told to roll them until thin and just insert, but adding the step of pulling the ear back really does do a better job. Also, you can watch this video at 1.5x speed and still understand everything in less time. Any faster and it is harder to understand. My question now is, does noise cancelling technology proven to reduce hearing loss?

[@xplodingkatz]

It is proven to reduce hearing loss, but only in small quantities, I believe.
And also I think it is easier to understand at 2x speed

[@replacesoundboard]

What noise cancelling does is called "destructive interference". You can learn more about it by having a look at the Wikipedia's page for wave interference.
TL;DR: It cancels out the noise you hear by producing a similar sound wave with a delay, so that what arrives at your ears is flat lined into a blank noise. Assuming your noise cancelling technology is strong enough to cancel out a very loud sound, what you would hear would be a very loud blank noise (which could still be dangerous).
Not to be confused with electric ear protection which provides passive protection, and the microphone amplifies tiny sound as long as there is no dangerously loud noise yet.

very good information. I will modify some of my practices. the presenter is an excelent public speaker.

[@williamalanwilliams8182]

thanks for the very informative video on hearing protection especially about the foam ear plugs, i thought you had to just force them in somehow and that was it! but having watched the video i know different now, and it's a lot cheaper than buying electronic ear muffs. Thanks for posting..Bill

[@faisalabbas1541]

Excellent explanation

[@BloodiedYetUnbowed]

The last youtube video I watched on hearing protection told me that ear plugs are by far better for noise reduction than earmuffs. In my experience, earmuffs feel -quieter- less loud than earplugs.

[@brentbarrus9754]

Depends on application, when I worked for a lawn maintenance company. Even the cheaper 24db muffs did a better job at minimizing the mid-loud humm of the machines. However, a cheap earplug, with 32db nnr--is far better for the range, if of course good technique is applied and seal is proper. Bone conduction(causing local vibration to drum) is yet another element of the equation. If indoors, it's recommended to double up on hearing protection if the measured sound climate requires an nnr rating of 27db or higher.

@@brentbarrus9754 i was very surprised when he said earmuffs r best in general. in my experience, a properly fitted, high quality foam earplug is better than any earmuffs i've tried. the ultimate is of course, both.

[@L1chtFarbe]

Very well explained and helpful.Thank you.

[@charlesdonahue7683]

Thank you. Solid information and a useful demonstration that can be applied.

[@AeroPR]

Amazing video. Very important information for shooting enthusiasts.

[@BeeeHonest]

Good knowledge, thank you.

[@danielmarshall4587]

Thank you, good presentation and information

[@suicideme]

this still a good resource when i want to refresh something

[@mybetterhalf6373]

Your posted info contradicts the efficacy of compression plugs to muffs. Perhaps some evidentiary citations from OSHA...?

[@luznarvaez1280]

Nice explanation. Thanks

[@mjt11860]

imo, formable foam earplugs r the give the best protection, if used properly & ur ear canals aren't deformed. the ultimate r foam earplugs & muffs.

[@re2ema]

Thank you

[@touch_master721]

IF we combine two protection, is that a double protection?

[@happycamper6352]

You reach a point of diminishing returns. Yes better, but nowhere near double, especially if you read up on how decibels are measured. Honestly, although this is a disappointing answer, it's still a very good reason to use both when feasible.

[@replacesoundboard]

Combining 2 solutions is better than using a single one. But yeah, there's a point where you cannot get any more protection, because the sound will propagate through your body directly.

What’s good against thunderstorms? Help

[@aar3682]

Thank you Sir.

[@GrimReaper-te7sr]

Does this goes for OSHA 1926 operations

[@trip_on_earth]

thanks for the explanation

[@ezhilarasanv5777]

Hey sir .. why have you stopped posting videos ?

[@braininavatnow9197]

Didn't you know? He was severely injured in an industrial accident at an adult toy factory. He's expected to make a full recovery with the exception of his fifth appendage.

[@braininavatnow9197]

Somehow I can't see this guy as being sweaty and dirty but I'm pretty sure he has crooked ear canals. He reminds me of the father on Happy days.
