Isn't 106 dB still pretty loud?

106 dB in a football field is STILL pretty loud.....

ITD · 03-25-2005, 09:04 AM

From this website: http://www.bassharp.com/nihl.htm

Some examples of loud sounds that can cause NIHL are:

· Motorcycle/Hair dryer/Lawn mower/Leaf blower 85-90 dB

· Wood shop/Chainsaw/Firecrackers (small) 100-110 dB

· Rock concerts 110-120 dB

· Ambulance Siren/Jet Engine at Take-Off/Pneumatic Drill 119-140 dB

NIHL = Noise Induced Hearing Loss

SAFE SOUND LEVELS:

T.W.A. Decibel Levels Maximum Exposure

85 dB ------------8 hours

88 dB------------4 hours

91 dB------------2 hours

94 dB------------1 hour

97 dB------------30 minutes

100 dB------------15 minutes

103 dB-------------7½ minutes

106 dB-------------3¾ minutes

The National Institute for Occupational Safety and Health (NIOSH) guidelines are stated in terms of the maximum time that you can safely be exposed to different time-weighted averages (TWAs) of sound pressure on a daily basis over a 40-year period.

106dB is very loud.......

Its extremely important to see *how* the 106db is supposed to be measured. Sound pressure levels decrease at the square of the distance. In my experience when you see a high number like 106, thats likely to be measured some number of inches from the outlet of the pipe.

Are Choppers exempt?

^^How fast can you mow the lawn??^^

Still has to pass the Senate, then the trouble starts. How do you enforce this law? There's only one place I know of that actually enforces that and that's Portsmouth. I love seeing all these imports with their big fart cans sitting in front of a Portsmouth police cruiser pleading their case. When it's all said and done it's just one more thing that make people resent officers of the law even more.

And yes, 106db is way too much. Maybe not at 6 inches or a foot, even then, it's still quite loud.

I think that the boat DB max is 92db ?

The problem isn't the level, it's enforcing it. Straight pipes on boats are illegal to. You can make the laws to reduce these levels, they need a better way to enforce it. Like they do with cars, at safety inspections. These sound levels need to have a consistant way of testing them to make them useful. Granted people still get away with these things but the inpection stations are at least a start. I'm surprised the state hasn't figured out that there's money to be made with inspection stickers for boats....then again...it's just a matter of time!

I think that is what will keep people honest.....

You are absolutely right. People will continue to find ways around the law, always have, always will. The burden though can be solely on the Police and MP's, they have other more important safety issues to address.

All this talk about loud noises reminds me of my commute home yesterday, stuck in traffic in front of this person who feels the need to have his radio so loud it is shaking my car, for 25 minutes I had to listen to this. Does the noise ordinance in NH cover this kind of noise or is it limited to exhaust noise?

Isn’t that a sign of being old, complaining about kids and their loud music? :-)

Don't worry, you've got company: Florida, that state known for its retirees, has just changed their "Illegal Stereo" law from 100 feet to 25 feet on loud car stereos.

More company: I see this morning that New Hampshire has just passed a No Straight Pipes law.

Personally, I'm ready for a reduction for boat noise -- both stereo noise and operation noise.

'Guess we're all getting old. How can that be?
