DIY REM (Real Ear Measurement)?

Yes, 2-4 KHz range amplification is fine, but the normal NAL, DSL and Signia in house formulas give amplification for 6 KHz to 8 KHz maybe 10 KHz, and the amplification suggestion on those frequencies are just too much, at least for me, maybe I’m the few guys that has normal hearing at 6 KHz up to 12KHz.

Thanks so much for outlining your experience with DIY REM. I appreciate it. I was wondering if the tubes on your REM machine are just long soft tubes that lead to a tiny microphone - some kind of tube like this: https://www.aliexpress.us/item/2255800362701831.html?spm=a2g0o.detail.0.0.6789mdExmdEx1d&gps-id=pcDetailTopMoreOtherSeller&scm=1007.40000.327270.0&scm_id=1007.40000.327270.0&scm-url=1007.40000.327270.0&pvid=fbf25b0f-0ad1-4924-91d2-3c1920658f04&_t=gps-id:pcDetailTopMoreOtherSeller,scm-url:1007.40000.327270.0,pvid:fbf25b0f-0ad1-4924-91d2-3c1920658f04,tpp_buckets:668%232846%238115%232000&pdp_npi=4%40dis!USD!0.37!0.37!!!2.65!!%402103243417037953492488193e1d09!10000002850071164!rec!US!!AB&search_p4p_id=202312281229094064165899907872570855_8

Just thinking about building my own DIY real ear measurement machine (just thinking, probably not gonna do it)

Yeah, the probe tubes that connect to a mic with the other end inserted in the ear are like those. Here’s a pic and specs from a REM tubes vendor: https://probetubes.com/product/50-probetubes/13

But I also think you’re probably not going to build your own REM machine. There’s a ton of audiological math embedded in the firmware of those devices to support signal generation, curve generation, display, etc.

I’m happy to have answered brec’s original question “Has anyone who does DIY fitting also tried to do REM?” just shy of 8 years later. Hope you’re still around Brec!

brec is still around – again, after a couple of absences. Apparently you (@DrJimmyJoeJimbob) haven’t been around since 2023.

UPS says they’ll deliver the MedRx AVANT REM Speech+ I ordered from an eBay seller next Monday; $2,500 + tax. I’m deep into the REM-study rabbit hole – books, articles, youtube.

@brec, so have you mattered it yet and what are your results compared to previous settings?

hoping to see this post reactivated as I consdider buying a DIY REM system as well. Brec? how did it go?

But why, unless you have $$ to burn, or just because you like tinkering around, seems very little benefits.
