We love to go to the races, and that’s just one of the places you need to be protecting your hearing at. Their are lots of places where loud noise is abundant including: concerts, fireworks, re-enactment days (or anything with guns being fired), monster trucks, touring an industrial plant, and many others. At each of these places if you do not wear hearing protection you will notice that after you leave you can’t hear certain noises for a bit. Over time it takes longer and longer and eventually you just won’t regain what you’ve lost. Due to this I keep a pair of hearing protection on hand for every member of the family.
What to Look for in Hearing Protection:
- A good fit – no gaps where noise can seep around them
- Comfort – because otherwise you won’t wear them
These reasons are why I like this pair. They are also easy store since they close up nice all on their own.
How does NRR change decibels of exposure?
When hearing protection is worn, your level of exposure to noise is based on the NRR rating of the protection device being used. Keep in mind, however, that while the NRR is measured in decibels, the hearing protector being used does not reduce the surrounding decibel level by the exact number of decibels associated with that protector’s NRR. For example, if you are at a rock concert where the level of noise exposure is 100 dB and you are wearing earplugs with an NRR 33dB, your level of exposure would not be reduced to 67 dB. Instead, to determine the actual amount of decibel deduction applied (when decibels are measured dBA which is the most common), you take the NRR number (in dB), subtract seven, and then divide by two. Given the previous example, your noise reduction equation would look like the following: (33-7)/2 = 13. This means that if you are at a rock concert with a level of noise exposure at 100 dB and you are wearing a hearing protector with an NRR 33 dB, your new level of noise exposure is 87 dB. If you are wearing a product with an NRR of 27 it would deduct 10 decibels (27-7/2=10).
