One important thing..
Some of you downloaded the awareness app, which is fine at least if you have got IEM's from etymotic - because the app is optimized for the ety earphones... Just saying you cant really count on the results not using an ety earphone, at least that is what they state on the website or in the app (cant remember :P)
I think i will try not going over 80 dB.
The idea about measuring by putting the mic to the earplug is a good idea, i will try that as soon as possible..
No not true. The main purpose with Etymotic and the Awareness! app is to utilize the iPhone/iPod mic on the MC3/HF3 so you can still hear things around you that goes above a certain noise level. For instance, you can still keep your IEMs plugged in and blocking outside noise, but when the App detects high dB, it draws that sound in from the mic so you can hear it, for example a cars horn or something.
So... Either way you can use IEMs with or without a mic. You just have to place the earpiece nozzle facing towards the mic on the phone to get a reading
