For this guide I’m assuming you have a functional measurement system & sound card set up. Make sure you’ve cleaned any goo or wax out of your IEM’s as this will affect your measurements.
For those that prefer to watch a video demonstration
First thing to do is sit MiEMi™on top of your measurement mic and make sure it’s inserted all the way. Then push the end of the rubber coupler back in on itself. Push the IEM into the rubber coupler as far as it will go (see photos). It’s important to push the IEM’s in as far as you can into the coupler. MiEMi has a 12mm long canal giving a half wave cancellation at around 13Khz just like an IEC711 ear simulator, so increasing the distance between the IEM & MiEMi™ changes the effective length of the canal.
You’re now ready to measure with MiEMi™, start your analyser software and you should now get a trace. I tend to use averaging of about 1 second to minimise handling and background noise interference and smoothing of around 1/3rd or 1/6th of an octave. I typically find I have to zoom out on the vertical axis (- button on SMAART) to get a decent view of the whole trace. If all goes well you should end up with something like the the image below. We recommend the following analyser settings for best results, set averaging to around 1 second and smoothing to 1/3 or 1 octave.
I tend to store a L&R trace for each band member’s IEM’s at the start of a tour and check them after cleaning each day. I generally clean them with antiseptic wipes & an in ear vacuum cleaner. By Measuring them I’m 100% sure they working when I give them to the band and can quickly identify any inconsistencies.

MiEMi-m™ is our top of the line aluminium in ear testing adapter. It’s laser cut aluminium plates make it more accurate than the original and the solid, polished aluminium body more rugged. It’s sold ready to use with a protective case. All MiEMi’s are assembled by hand and tested. MiEMi-m is currently only available in 7mm(1/4″) size,…
