Allowable noice levels

[ullbergm]

Anybody know what the acceptable noice levels in a work environment is?
Or what levels are considered 'safe'?

Personally i always use a face shield and hearing protection when running the CNC, but im curious how bad it is for you to stand in a 102 dB environment (that's what the 7310 porter cable spindle cranks out)

That's way too much.

Prolonged exposure to those db's will be harmful. If I remember, 60+ can be harmful after prolonged exposure.

OSHA's permissable noise exposure for 102 decibels is 1.5 hours. If you do a Google search you shouldn't have any problems finding the appropriate information.

I can't seem to find any listed requirements for under 85db. I'm no expert, however.

Decibel Sound Pressure Level expresses the sound pressure level relative to 20 micro Pascal (µPa). 20 µPa at 1 KHz is the weakest sound level a person with normal hearing can hear and is defined as 0 dB SPL. Sound pressure at 20,000 µPa is equivalent to 60 dB SPL, which is where you hear normal speech.

No wonder I'm going deaf! I fart at 105db, 20 times a day for 47 years. At 1 second duration, thats 95 hours of farting

ROTFLMAO!

Master, you must teach me.

I love it! Woo Hooo

Its official, the zone now rules.

I believe OSHA limits are 82, 105 is definetly a "Better not do" db.
You can never go wrong wearing ear protection. Look at Hu, even farting has affected his hearing over long periods of time.

The best hearing protection available is the Howard Leight LM-777 or their foam ear plug MAX-1.

Hu, where in the crap do you come up with thi stuff?

ullbergm send me your address (USA) and I will send you a couple pair of the MAX-1 to try.

Hu, I really, really enjoy your humour!!!! On a points based scale i must give you 11/10, just an extra point for your wicked(?) sense of humour!

To counter deafness you must learn to f**t different. We call it: "silent but violent" f**ts!

I have noticed after riding my scooter with my pals, and stopping for a break. We all scream at each other. So I wear hearing protection on long trips.

However, after working in the shop all day, I have trouble hearing my daughter for a an hour or so. But when I wear ear plugs, I can't hear the tones of the machine. I feel it's better to hear the equipment in case something is wrong. It's just to costly to miss a problem, and destroy components. I have found no ear plugs, that block minimal noise only.

It may not be right, but it's my viewpoint...
