I just got my pair of Etymotic ETY-Kids5 IEMs.  I'm trying to figure out what the sensitivity of these IEMs are in db/Mw or db/v.  The only specs I was able to find were the following:
 

Frequency Response	20 Hz - 15 kHz
Accuracy Score	85+%
Transducers	6-mm neodymium moving coil drivers
Noise Isolation	35-42 dB
Impedance (@1kHz)	300 Ohms
Sensitivity (@1 kHz) SPL at 0.1v	76 dB

Is it possible to calculate, or can anyone find, the sensitivity in db/Mw or in db/v terms?  Here's the link to the IEMs: http://www.etymotic.com/ek5.html

You are given the SPL at 0.1V so all you are looking for is the SPL at ten times that voltage. Ten times voltage is equivalent to 20dB, so the SPL is 96dB @1V.
 
If you want the other units, the voltage on 300Ohms at 1mW is 0.55V, which is 5.5 times larger than 0.1V, which is equivalent to 14.8dB, so the SPL is 90.8dB @1mW.

Got it. Thanks for the prompt response!
