What material can you use for ear defenders?
Foam, rubber, and cotton wool can be used for ear defenders.
Why does cotton wool absorb sound?
Believe it or not wool is a solid. Its fibers vibrate when sound approaches it therefor the vibrations are used up and there is less sound coming out from the other end of the wool fiber. (I'm Not Sure If Its Al Right But I Do Know that wool does absorb sound and It Can Be Used In Ear Defenders Or Ear Muffs To Cancel Out Noise).
Why is cotton wool good for making ear defenders?
Cotton wool is a very poor ear defender against sound. The best hearing protectors are the preformed foam plugs that one rolls between the fingers to compress, then inserts into the ear canal before they expand. Some are more effective than others, but a noise reduction rating (NRR) of 35 is about the most effective.
Why is cotton wool a good ear defender material?
Cotton wool is NOT good for hearing protection as it only has an average attenuation of 7dB whereas you require 25-30dB in an average metal workshop for proper protection. DO NOT use cotton wool as hearing protection EVER. If one tiny little cotton fibre gets left behind you're in trouble - ear infection on the way!
