They also supposedly cut out at 120 DB, which while not particularly good for your ears, isn’t going to deafen you instantly. I don’t know how well this works, and I hope I don’t find out.
At 120 dB OSHA states that significant hearing lose begins after only 7.5 minutes. Of course, this is for prolonged exposure to 120 dB. If you are hitting peeks of 120, you are almost certainly averaging 110 dB, which will cause damage after only 30 minutes. Also, remember that these levels are cumulative. ANY exposure to high sound levels causes some damage. You should NEVER use in ear monitors without a limiter in line, and if your transmitter has one, add another of your own.
Also remember, OSHA is talking about SPL at a distance. The levels coming out of in ear monitors is much more serious, and much faster. The speaker is very close to your ear, and there is no where else for the pressure to go, because the ear pieces are blocking the pressure in. When your ear is open, IE when you do not have ear plugs in, the excess pressure can escape (a little, not much). The same is true, to a lesser degree, with headphones. I would never want to have more than about 80 dB present at my ears when using in ear monitors, which is not very loud. This is why the custom ear molds are such a good idea. They keep out more outside noise, so you can keep the level of your in ears lower.
Bdgr, I am glad your band is comfortable with the system you are using, but I would highly recommend you get a limiter in line between the mixer and your ears. It will save your ears.
BTW, Dave, I think you could be a good candidate for in ears. Just remember to get a limiter in line, before your transmitter. Spend some money on this, because this is the most important line of defense for your ears. Do not skimp, it is not worth it. Do not trust the limiters built in to the transmitters, but use them as a back up. My guess is that your stage volume is not very high, so may be able to get away with not using custom ear molds, but it would be a good idea none the less.
As far as brand, I do not have much of an opinion. It would be best if you could try them out, as this would give you the best idea of how they sound, and which ones you like the most. I would also like to see you try them because many people decide the hate the feel of in ear monitors. I always have bands try them a few times before they make a decision. It is usually good to have stage monitors for the first few shows as well, because if you decide you don't like them, or if something goes wrong, you have a backup.
