It seems like Rin's and Piotrus' are more similar

So when I do take measurements, I'll have to keep in mind that the bass part will be between the blue plot and the red plot. LOL

That's very cool work bartz! Thank you.

non related, but I really miss the search feature and the picture gallery for each thread. It made browsing and searching so much more efficient and interesting.

Well we both use ISO certified gear and I think differences boil down to 1) relative volume 2) output impedance 3) insertion deep

I wouldn't say Rin's and Piotr's are more similar. Here's Rin (yellow) vs Piotr (green) and your blue vs red in one plot:

As Piotr already stated he and Rin use certified gear, so the deviations between those measurements will most likely be caused by other reasons than in your measurements. Since the UERM is custom molded there might be huge differences in shape. Imagine Piotr measured a UERM from a person with big ear canals while Rin measured a small UERM that inserts very different into the coupler.

Do you have an amp with low output impedance you could use with your blue setup to drive the UERM?

That's very cool work bartz! Thank you.

You're welcome!
The picture gallery feature was great, I miss that too. Let's hope they'll restore it soon. Have you tried to use the google picture search in the meantime? Like this: Link

Rin had made his own measurement rig.
UERM irrespective of size should measure same and that is controlled by QA.

Well sure, but it will still be dependent on insertion depth.

Hello,

I am Fabs from Stuttgart Germany and I am reading a long time here.
I like to build stuff by self and that's why I want to make some ciem`s

I was in a hearing aid store and make the impressions.
And now i wanna try to 3d scan them and send a friend with an sla printer to print the shells. I hope this will work.

Does anyone use cerumen filter to protect the iem from earwax?
Or have they some bad influence about the sound quality?

 

[MuZo2]

Welcome, when you print it use only bio-compatible resins. What scanner are you planning to use? After scanning you will need to model them a bit. Cerumen filter I have seen them only on InEar brand. I wont use it for first build as it will be hard to incorporate it in ciem specially if you plan 2-3 driver ciem.

Thanks for all the great info in this thread. I made my first pair with Dreve fotoplast and UV lacquer. The faceplates are Kirinite. Knowles 3 way.

My third pair. GK inside. Red & white dampers.
Sounds strange. Some tracks sound great, others are unclear. Overall impression - too much bass, low-mid.
Pros - good sound insulation. Moving on the subway or bus, I do not hear the ambient noise and can listen to music at a low volume.

I have tried two different translucent 2 part silicones. Moldstar 20T and Trollfactory TFC Silikon Kautschuk Typ 13.
The TrollFactory is less viscous, and softer when cured. Both have the same pot life, cure times are longer with Trollfactory, 60 minutes vs 30 for the Moldstar.
Does anyone know where I can buy a silicone in the USA that has the same properties as the Trollfactory silicone?

Hello all, I just finished making a new rotator and wanted to share with everyone. Again it is used for laquer coat for even distribution.

I used a project box and decided to have two motors this time, both with there own on/off switch.

Great video find. The way they do some of those steps never would have occurred to me.

 

[Shilohsjustice]

A while ago I said I would put together a tutorial on how I make the rotator I use with my IEM's.

Well, the time has come............ I am going to show everyone how I made the rotator below.

I made my own sleeve that goes over the tip for an alagotor clip to slide in.
