## Questions & Answers

**Q: will they cut out quarrelling neighbours - and noisy traffic?**
A: Most of it definitely. Neighbours for sure and as for the traffic - depends on how noisy it is of course and how close to it you live. What even these babies can't block out completely is bass since we, the people, not only hear bass with our ears but feel it with our bodies and car engines can produce some fairly low frequencies. You should be fine from low mid to high frequencies so you won't know about the neighbours as long as they don't throw each other at the walls which would naturally produce some bass. ;)

**Q: Why SNR 5 db? Should it not be SNR 35 db?**
A: Yes it should be - Typo ...

**Q: I go to a church with very loud levels of live music.  Will the 3M Peltor Optime III be suitable for me?**
A: Technically yes - I use mine for when I go shooting at a range using military rifles; noisy would be an understatement. No problem, also you can hear normal conversation when wearing them. From a fashion standpoint - big and bulky. Horses for courses.

**Q: I work in live music - how much will these cut out? Ideally I want to hear very little**
A: I work in construction these will reduce the noise level but will not cancel everything out they are rated up to 110 db the next highest rating is for aircraft the optime 4 always look at the db rating
