Boring rant about protecting your hearing and your range ahead:
Just for fun (and curiosity) I brought out my noise dosimeter to the range which is adjacent to a USFS ATV park. Been some complaints about the range from area residents and my work as a registered engineer and industrial hygienist got me wondering. In short, most ML rifles and unmentionables can peg the meter at 135 db when within 5-20 feet from source. Drops off to sub 100 with distance and sub 80 at 500 yards or so. According to experts Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears. With noise, OSHA's permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. My hearing is already shot from being assigned to a fighter squadron and the ringing is irreparable but manageable with $5000 hearing aids. Bottom line - really should wear some sort of hearing protection when shooting or even standing near others while they shoot. Might not hurt then but start saving $$ for future hearing aids. As for the range i found only individual shots measured up to 70 db off range and so within limits for those trying to close us down. Did same for local USFS Dune Buggy ATV park during peak use and found constant 120 dB in the park with lots of sustained 135dB exposure to riders. One wonders if USFS is liable for all those deaf kids???
