Yep, it is a 4 hour appointment, but of course not all of it is in the listening room, there is some discussion and recap time in their. The actual fitting was at a later appointment so not included in the evaluation appointment but the fitting one did not need to do any real testing except after programming and installing and a resonance/response test.
I can tell you that keeping concentration on listening for the long periods of time was difficult and exhausting, which they know and tell you it is going to be hard up front. There are breaks, also, a couple of times. I don’t know how many tests or what they would called, but they did seem to go on forever. Lots of different voices from male to child, different sentences and words for all of them, different speaker placements for full 360 degrees and angles, with and with many different kinds of noise overlaid.
I think, to me, the proof of if it was worth it was at the fitting when they were programmed and put in. The only test done then was for resonance primarily and two ranges were adjusted for that. I heard surprisingly well right out of the door with them and that had never happened in the past with any audi or fitting specialist.
After all my home tweaking and testing, my gain curves are still very similar to the original programming and initial tweaks with mainly compression changes to balance loud and soft. I actually wish I could get more than 3.0 compression the programming allows for certain frequency ranges. Different microphone settings, especially the auto directionality ones, do make for some gain curve necessities, though.
Where I was able to make the biggest gains in hearing quality was mostly related to the multitude of “automatic” features available. Lots of directionality, noise canceling, ear to ear transfer, spacial effects, etc so very many combinations available. What I found was that there was a lot of conflict between them and also that they could pretty easily get fooled by quickly varying, or unusual situations, especially if more than one them was on. The most stunning of them showed up while riding my bicycle of all places. They were set for “front focus”, moderate noise reduction, and with ear to ear communications on. The aids sit just below the helmet edge and the wind does make noise there, it always has with any aids in, but with these settings it took the wind noise which is a lower frequency noise as voice it appears, focused on it and amplified it, and then doubled the volume again by ear to ear communication. It was like freight train sound. If I turned off one aid, the noise went to about 1/4 the volume.
I currently am running very well, best ever, with fixed directionality that is said to super or hyper cardoid, low noise reduction, ear to ear communication off. Gains, particular on the low input/high gain curve have been tweaked slightly to match the noise frequencies that seem to interfere with speech for me the most. Cochlear is in the future, but this is certainly usable in the real world pretty well.
