Etymotic ER20BP or Hearos High Fidelity ear plugs?
by

1 Answer

Answer :

answer:I have used various plugs from Hearos. They work. If you look at the attenuation data on their webpages (http://hearos.com/earplugs/products-00211.html , http://www.etymotic.com/ephp/er20-ts.aspx) you will notice that the low frequency reduction is less than mid or high frequency reduction. It will sound much better than normal foam ear plugs but they will not protect your ears as well. So don’t think you are stopping all hearing damage by wearing them. As you can see in the table, you get about 20db or reduction. If you go to a show the sound levels can be 100 to 110 dB. So you are still being exposed to 80 to 90dB of sound energy. But still they are better than nothing. It looks like the Etymoyic might often a little better noise reduction. Good luck
