This is a plea for help. I want to know where and how in the Sam Hell the even 140 dB number was decided as "ear safe". Email me your knowledge/findings to 140dB@LaRue.com. I find it hard to believe that an even number 140.0000 is safe, but 140.1 ain't. Enlighten me-go. ML

jeff_iwanciw OSHA pulled a number out of there ass and askd a magic 8 ball was that number good enough.

ryan_brady23 I'm guessing industries where a lot of hearing damage occurs, contribute greatly to this decision, to avoid paying disability claims for long term employees. I think of the railroad industry, factories, and airline industry as having the kind of deep pockets to influence that kind of decision.
txduckgun 140bB is a full 24 hour dose exposure max.
- laruetactical @txduckgun .... and who authored that ?
- txduckgun @laruetactical its an OSHA reg/standard. Which means your taxes paid for it. Which also means its generic and everyone's tolerances are different. And it also means it's pretty arbitrary but based on funded research and lengthy debate. If you've ever seen a standard developed (asme, api, sae, mil, ect.), it a bunch of eggheads in a room.parsibg each workm 3 likes

- txduckgun @laruetactical I would never defend any osha regulations as they are not based on real world conditions. But the problem is that they will stand up in a court of law in negligence cases. When someone is in a work related accident, the presence of ppe and engineering safety controls have to meet the minimum osha requirements. Failure to use provided ppe that meets the requirements can leave an injured employee without a case. Conversely, an employer that fails to provide such controls can be found to be negligent. I feel that 140 is too loud but it's to late for me because I'm already deaf from noise. 1 like

- jeremy_sensing @txduckgun osha max DBa for an 8 hour day is 85 dB. 140 is immediate loss of hearing according to them. Not sure where you got your info from but NOWHERE is 140 considered safe for 24 hours.
- txduckgun @jeremy_sensing dose= intensity and time. If you receive a momentary 140Db dose, you cannot be exposed to any more noise for the next 24 hours per osha regs. I was not stating that a person should tolerate 140Db sustained for a 24 hr. period
- jeremy_sensing @txduckgun makes much more sense 😂. I thought you were smoking the reallly good stuff the way you worded it haha.
- txduckgun @jeremy_sensing 🤣 Well, unless you're being interrogated. Then the 24 hour exposure to 140Db will surely make you talk.
chevy_blackbear I've heard some where that 140 was what a 22lr rifle puts out and is "safe to use" with out hearing protection

whitesys99 A good sound level meter will have maybe a +/- 1 db accuracy. The 0.1 db difference can't be measured.
whitesys99 Also a decibels are logarithmic. A 3db increase is twice the power or intensity.
whitesys99 A 10db increase is 10x the power.

brianbelden @laruetactical I flew on an AC-130U Gunship for about 9 years, and never wore any ear plugs. If anyone has ever been on a regular C-130, they know how loud it is. On top of that, add in a bofors canon, howitzer, and a Gatling gun. Every time I've had my hearing tested since then, I've been told that I practically have dog hearing. So I'm with you. I don't really believe in the 140 thing. These days, I work in a structural steel fabrication shop, around grinders and carbon arc gougers, without ear pro, and still have hearing that amazes every doctor who's ever tested me.
- adammichaeln @brianbelden most retarded comment ever. Just because you're the exception doesn't make it the rule. In general any noise over 85 dB is too loud for human ears and this is extensively tested. Even rock concerts can cause hearing to muffle afterwards and cause ringing of the ears. If you can't hear the person next to you talking, it's too loud. 1 like

raydrawsagain We have a safety company come around & sort of "osha proof" us & we're supposed to urge hearing protection at 80 & make it mandatory over 100 or 105 so 140 seems absurd
d.w.jones No way!!!!
helsley.b According to the National Institute on Deafness and Other Communications Disorders: it's not 140db sound that hurts your hearing, it's the repeated exposure. According to them repeated exposure to 85+ decibels can cause hearing loss. And the more decibels the less exposure it takes to begin damaging the ear. 1 like

jointdocshields Publishing a paper on this now - noise in the operating room - but essentially damage that occurs causing irreversible hearing loss is due to sound or length of exposure... 140db is the "safe level" they set for a percussion sound to not cause irreversible damage. They also look at exposure over time in workplace environments.

- engineer59 @laruetactical osha is based on an industrial setting, I would guess gun shots although it is are listed on the data I believe as examples, probably not considered for sustained exposure. (Hunting perhaps) OSHA also based it on an 8 hour work day. So if your exposed your supposed to be removed from the area for example until the next work day. I work in a cogeneration facility on a 12 hour shift if im exposed to that level of noise I put my ear protectors on and go back to work. It's a guideline that is not very practical depending on your employer. Sorry long winded reply.
- fenton1441 @engineer59 the military basically told OSHA their regulations we're worthless. OSHA replied oh yeah? Are you going to pay for the research that is going to cause millions to claim disability?
arkangelsklucifer Above 140db is immediate hearing damage. Anything below they have second(s) to minutes till harmful.

- a3addon @laruetactical that's going to be hard to trace. My guess is that it stems from a lawsuit or accident. Just like the Triangle Shirtwaist Fire in 1911 gave us the modern life safety portion of the building code. People were trapped behind doors that swing in and were locked. Now we have panic hardware on doors that swing out (depending on occupancy). Almost all building codes stem from an accident or a lawsuit resulting in loss of life or limb. I'm sure if we really dive into it we can find where the standard came from. Unfortunately I'm not a member of OSHA like I am of NFPA and ICC so I can't call and ask, but I'm sure there is a way to find out. 3 likes

leigh42513 140 dB sustained exposure is different than 140 dB impact exposure. A noise survey is what you need. You can do area noise or personal dosimeter to determine the time weighted average (TWA) the employee was exposed to the noise. 140 dB is excessive and extreme but over an 8 hour period it may not be enough to cause permanent damage to an employees hearing. You'll be looking for a standard threshold shift (STS). To measure this the employee needs to have a baseline test created. You'll probably need to create a hearing conservation program. 4 likes
