 I'd like to talk to you about noise and what noise can do for you. We got a new rule, part 62 that come in effect and I kind of like to talk about noise injuries and stuff. First, I'd like to say when you get injured a hand or a foot, there's pain right away. You can feel it wearing noise. There's no pain. You don't feel it like you smash your thumb right away. There's instant pain. With noise there is no pain and you really don't know you're losing your hearing. But I kind of like to talk to you about decibels and also about intensity and what noise can and can't do for you. What decibels is, is the volume of noise, how loud it is. Intensive, there's wavelengths in the noise. I like to demonstrate on a guitar the difference between the two. A lot of people think high pitch noise are worse because it's higher pitch but it's not true vibration. I'd like to talk about the intensity of a low bass, low sound. The wavelength would be further apart and it lasts longer. This would be like in your crusher sounds, your bearings. When you're using bearings and there's something going wrong with it, there's low vibration which causes a lot of vibration and stress on your structure. You could have things coming apart, not know it. This top string on a guitar is an E string and if I hit this E string I can feel or hear the vibration for at least 11 seconds. So I'll show you. I can still feel the vibration of the guitar. This would be like on your machinery, equipment, something island, low speeds. A lot of vibration causes a lot of stress on structures and stuff. Now here the E string is also, the bottom string on a guitar is also an E string and it's higher pitch and your waves would be closer together. This kind of sounds louder but it's actually less vibration and when I hit this string I can only feel it for about 5 seconds, half the time. So it's about half the time the high pitch versus the low pitch. Now the decibels is a noise, anything over 80 decibels. You can work 16 hours, 85 decibels. You can work 16 hours, 90 decibels, 8 hours. When you get 5 decibels louder on each scale then you can only work half that time so it cuts your work force down. 90 decibels I work 8 hours and be safe, 100% of the PEL. If I go 95 decibels then I can only work 4 hours so see that cuts it in half. And that doesn't matter whether you're wearing earplugs or not, 95 decibels I can only work 4 hours with plugs or without in that area. And what I did is my boss challenged me, I play in a country band and he asked me, he says write a song about this noise so here's what I kind of come up with. You want to do the song again? I should have had to listen cause I can't hear today. My best friend works in the gravel pit, working around crushers and dust and bits. I think his hearing is worse than mine, he's hard to talk to, he says what? All the time they're making new laws to cover these sounds. So we have to get those desk bubbles down. You have air arcing in the MG sets, impact noises over 8 seconds, and all the vibrations from the crusher sound. So we have to get those desk bubbles down. So where, where did my hearing go? It was alright about 10 years or so, got to do what they say, or it gets worse every day.
