crinacle's FR measurement database (188 IEMs measured)

post #1 of 199

DISCLAIMER: READ THIS BEFORE YOU USE THIS DATABASE

 


 

Setup: Dayton IMM-06 with makeshift vinyl tube coupler, "FFT Plot" app on iOS

 

With this portable measuring rig, I was able to run around the country to take measurements off demo units. Will be updating this post and the imgur album as I get more and more opportunities to do so in the near future. Due to the nature of this setup, I will only be measuring IEMs.

 

Disclaimer: my measurements are not meant to be totally accurate or conformed to any standard. Do look at my Etymotic measurements as a frame of reference instead.

 

Measurement procedure (Click to show)
Every unit will undergo a right channel preliminary check at a 5-second averaged curve. The IEM tip will be forced into the tubing with as much of the bores exposed as possible, with the distance from mic to tip set at 12mm for standard inserts, 14mm for shallow inserts and 10mm for deep inserts.
 
Left channel will then be checked. If the two curves are 90% similar (by observation), proper measurement will commence on the right channel.
 
Measurements are done on the "FFT Plot" app with the following settings:
 
 
If inconsistencies are detected, measurements will be repeated on either the left or right channel (depending on situation I.E. channel imbalance), until a curve can be properly reproduced.

They seem really accurate. Definitely, it's a very good work!

post #3 of 199
Great job, bro!

Can you add in a reference IEM to the FR graphs in FFT Plot for comparison?

EDIT: Your measurement rig looks eerily similar to mine wink_face.gif



SECOND EDIT:
I'm going to get that app and try measuring my IT03. One thing that would be helpful is if you could include which tips you used during measurement. Some IEM / tip combinations do adjust the frequency response enough to easily detect with IMM06 + Audio tools APP. I'm sure you could detect them with FFT Plot, as well.

THIRD EDIT: How long have you had your IMM06?

Unfortunately not. The FFT Plot app isn't really powerful can't do a lot of things. However, anyone's free to reference off my catalogue, though I recommend the ER4XR as the neutral benchmark.

I suspect something's off on my IT03 as it's not detecting the 8-9K spike from the manufacturer's own measurements. If I remember correctly, it was on stock tips at a 12mm spacing.

I had my IMM-06 for about two weeks now.

Cool beans, man!

Perhaps we can chat via PM, synchronize our technique, and expand this thread to include more measurements. I've already measured lots of IEM and have them in my AudioTools database. Let me know what you think...

Yeah looks like my suspicions were confirmed. Maybe the unit I was using was faulty. Are you using pink noise or white noise?
post #8 of 199
Using Pink Noise with FFT Plot looks like this for IT03:



That just doesn't look right to me. IT03 don't skimp on bass, but they're not bass monsters like that. Some serious correction would need to be applied, I fear...

thanks for the enlightning post!

can you compare oriolus and oriolus forsteni please? fr graph seems similar, can forsteni keep up?

@crinacle posted links to FR Curves for the Oriolus IEM in the first post. Check them out!

I wish FFT Plot allowed multiple FR Curves to be compared, normalized at 1kHz like AudioTools allows. That's really, really handy!!!

I think I'm going to contact the developer for FFT Plot and see if they can incorporate that functionality...

i already mentioned that i saw both graphs, asking for more detail? can forsteni keep up with micro details, soundstage etc.

No your first graph was correct. White noise is most accurate on a non octave-smoothed software like FFT.

At any as for now, disregard my IT03 measurements until I get another chance to measure. Plenty of demo units floating around the island...

I thought the MK2 and Forsteni were more or less the same in terms of performance, honestly. In fact, I preferred the tonality of the Forsteni.

The MK2 has a more energetic midrange while the Forsteni is more laid back while retaining airiness. Really loved it.

I simply misunderstood what you were asking. Glad you asked the question,though. The Oriolus are two IEM I'm very interested in, as well!

What kind of dB range are you getting? I'm usually measuring at ~90dB pink noise in AudioTools.
