So here's a weird one.

I'm pretty much aging out of live sound mixing, because my ears have gotten too sensitive. Loud actually hurts, and more importantly loud causes distortion and I'm not hearing accurately when that happens. So what I'd like to find is a way to reduce the volume but still hear reasonably accurately.

I do have custom-molded Sensaphonics earplugs, and it's not good enough. Weird things happen to the very high frequencies.? I fooled around a little with mounting one of the filters to my Earthworks M23 test mic, and while I didn't get any useful frequency response readings (can't properly measure the full "system"), I did notice that the phase trace got rather delayed at higher frequencies.

So what I'm experimenting with right now is some kind of stereo mic array to go with my in-ears (Sensaphonics).? A basic ORTF with either Alice or CAD E100 seems sort of OK, but I'm wondering about something like a Crown SASS type thing, or maybe a dummy head. Possibly just a sphere? Anything I could try out locally (northern Chicago burbs)?

Mono compatibility is not a concern, just trying to match to reality but be able to turn reality down.? The ideal is something that packs relatively small and just plugs into whatever mixer I'd be using.

The good news is that the bulk of my paycheck does *not* come from live mixing these days. But I hate turning down gigs that would be fun to work.

Thanks,
-Scott

Hey Scott,

Yes, conventional wisdom for headphone monitoring would point towards a binaural array.

I have had pleasant results with a 180mm spherical baffle and a pair of omni capsules. A big shoutout to Jerry Bruck and his work with Schoeps for the KFM6 and KFM360.

I posted photos of my first attempt. The 3D print was pretty rough. I have been toying with the idea of modifying a molded sphere with flush mounted capsules because it is A LOT to print. If appearance is not a big issue you could use any rigid sphere of the right size, but you need to get the capsules as close as possible to the boundary layer. One client calls it the "Bunson Honeydew" mic. It has a lot in common with Binaural, but plays back ok over speakers.

Sorry it's not super compact.

I had a lot of fun recording with a Jecklin ?disk- a thrift store LP with foam sheets glued to both sides, omnidirectional condensers pointed toward the center with 3-4” spacing each side. I used a stereo mic bar and a microphone close-pin clip to support the disk. Easy to set up, packed small.?

No reason I can think that it would not work.?

My problem with live mixing is I can’t hear much above 12K now. Age does that to you. And too many years mixing in clubs. ?

Thanks!? Agreed on the top octave going away, but as long as I can hear without distortion I can do a good mix.

A few years ago we had a demo of an IEM system that include ambience mics mounted right on the earbuds.? It was actually pretty good, basically you could walk around and turn the volume of everything up and down. So maybe I just need to add tiny capsules to my earbuds... or clip to my glasses or something.

Will have to dig through the "unrepairables" bin at work, we've got some DPA headsets where the wiring failed and isn't repairable for practical applications.... plenty good for experiments, though!
