I concur, the N1 is L-O-U-D!

I am one for extremely loud cars and exhausts.... but something about the n1 made it unbearable to me, and this is coming from cars with no exhausts/cut-outs.

Needless to say I sold it and would never consider it again.

Since this topic seems to be somewhat related ...

I do a lot of work with pro and computer audio. Hearing is my bread and butter. I also unfortunately have tinnitus and had one (successful) bout with SSNHL.

Youngsters. Protect your ears. Constant, permanent ringing can (literally) drive you nuts. If your ears ring after a concert, after listening to your headphones, or a long drive ... you are doing damage to your ears.

Unfortunately, I didn't take it too seriously when I was younger (in my teens and 20s). I blasted my walkman, went to lots of loud rock concerts w/o ear plugs and had a stupidly loud exhaust on my 1970 GTO. I've also had a few "studio accidents" which I'm sure haven't helped.

Here are some links, the first by someone you may not expect, Captn Kirk!

But more to the point, here's a snip from the OSHA standards (quoted from http://www.termpro.com/articles/hearing.html):

"To provide a basis for determining safe sound-pressure levels, OSHA has established the following guidelines: For sound-pressure levels of 90 dBA (A-weighted decibels), the maximum allowable continuous exposure time is eight hours. For every 5-dB increase in SPL, the allowable exposure time is cut in half. Note that OSHA regulations prohibit exposure of any duration to sound-pressure levels above 115 dBA unless hearing protection is used. Unfortunately, levels of 120 to 130 dBA are fairly common at sound-off competitions. "

So if you're cruising around at 110db for more than 30min ...

Food for thought.

The legal limit in California is now 92 db(I thought it was 95 db as well but they changed it). This is coming straight from my neighbor who is a CHP officer. We always shoot the shit from time to time and his biggest problem is the Harley guys that put straight pipes on. They've wised up though, on the third(loud/modified) exhaust ticket and they can't just get it signed off anymore. They have to pay a large fine and the vehicle will lose registration along with a notification to the insurance company to drop them. This is the way it is in SD.
