Hearing Protection Training Kit Instructor Script

These earplugs have a rating of 29 decibels. Subtract 7 from that and you have an actual reduction of about 22 decibels. So if the noise level of this grinder you are using is 95 decibels, then these earplugs, when properly inserted, will reduce the noise to your ear to about 73 decibels and you will be protected from damage to your hearing. ................
