I've just started using earplugs when I practice at home. I still have to try them when I play out. At first, I had a lot of trouble hearing everything, but now I think I got the hang of it. It definitly cuts of those high frequency that can kill your ears.
At first I didn't like to use them. But, if you like your music loud like me, then it's time to use earplugs.

ER-20 just lowers down the volume and doesnt really kill the sound quality by much. The foam ones are horrible but I'd use them if theres nothing else around.
Hearos also has ER-20 clones bit with a blue stem and they can be found at Guitar Center for $15.

It has been demonstrated that labeled NRRs based on the ANSI S3.19-1974 formula show little resemblance to actual protection achieved in typical real-world conditions.7 Example: Clinical measurements of properly inserted ER-20s indicate that these earplugs provide an average of 20 dB attenuation across frequencies, but the labeled NRR of ER-20 earplugs is 12 dB. The required formula used to determine NRR includes an adjustment for individual variability and for those persons who don�t wear hearing protection as instructed. NRRs for foam earplugs are artificially high (most users obtain less attenuation than the NRR label indicates7) and NRRs for ER-20 earplugs are artificially low (most users obtain more attenuation than the label indicates1).
...The NRS for the ER-20 earplugs is 14 dB (�low value� which 80% of users should be able to exceed) to 20 dB (�high value� which highly motivated users may be able to achieve). The 6 dB range between these values was the smallest range for all 20 hearing protectors measured, indicating less variability and better reliability with flat attenuation earplugs. |

I bought a Scosche SPL1000 digital decibel reader for $20 and took it to Ten15 recently -- I think it was the 16th of this month, discodave or lex400sc may remember since they took it around the main room too 
Average was [b]116dbish and peak was 120db through out the night. It seems kind of low but I can't really say its wrong since your reader tops out at 105 and even the sound engineer, Marie, at 1015 said that Scosche was legit stuff.

So, if the ER20's are used at 1015 Folsom and the sound levels are same as above, here's the math:
116dbA (low range of measured sound at 1015)
less ER20 attenuation:
14dbA for 80% of users
or 20dbA for 20% of users (who are "highly motivated" and achieve a perfect seal)
Equals unattenuated sound level of:
96dbA (80% of ER20 users), or sound is harmful after about 7 minutes
102dbA (20% of ER20 "highly motivated" users), or sound is harmful after 30 minutes to 1 hour
Now, if the sound peaks at 120dbA as mentioned, the unattenuated level is 100-106dbA, or sound is harmful after 4-15 minutes using the ER20's
(Source: Decibel exposure guidelines from CDC/NIOSH, see first page)
All that said, using the ER20's is better than using nothing! Seems that clubs should limit the sound levels to 100dbA, then pretty much all people using ER20's would still be in the safe range, but that's not reality. Until that happens (with a sign on the door and monitored by the feds with a $1M penalty, since it could be different week to week) I'll keep wearing the foam HEAROS earplugs.

I only turn the booth monitor up when i mix, then turn it back down / off to save myself. |
I'll let you know how my set goes this Friday when I try out earplugs this time. I'd assume the worst time to be exposed to such high levels of volume is when your djing.

With Lovefest and Nocturnal just days away I hope everyone invest in some kind of ear protection.
Rizo, if you have room in your bag you should bring that little device that can measure the decibals at Lovefest. I can imagine them being much louder than a club with all the crowd noise as well.

...although dry tissue provides virtually no sound attenuation, from what I've read. If nothing else is available, wet tissue may provide some attenuation:
http://www.audiocheck.net/earplugre...toiletpaper.php
"To get the flattest attenuation out of toilet paper, moisten the paper under a water tap, remove the excess water by wadding the paper, then stick it in your ears. Beware : dry paper doesn't attenuate the lower frequencies at all, as measured during our tests."
All clubs and loud events should be required to sell earplugs at a reasonable price, period. That's really only the effective solution.
I know that for Ferry at the Shrine, the candy and glowstick booths had earplugs for sale, so that's a good start, and Cow Palace was on top of it. Avalon and Vanguard sell earplugs in the restrooms, haven't seen them at Circus yet though (maybe this could be done at the coat check). It's sad when I see people with their fingers covering their ears the whole night...that must be really uncomfortable and dangerous, especially when earplugs are like $2 pair, at the most!
Update:
{Source: Hearnet.com} October 9,2002 Entertainment Commission Hearing:
Earplug Ordinance for San Francisco Entertainment Clubs
Resolution was passed and sent before the full Board of San Francisco Supervisors [Amend Police Code Sections 1060.28 and 1070.27 ] Ordinance amending San Francisco Police Code Section 1060.28 and 1070.27 to require places of entertainment and after hours premises with a dance floor and a capacity of 500 persons or more to provide or sell at a reasonable cost earplugs to patrons.
Looks like SF has things covered, it should be law everywhere else as well!
