Hmm, I figured. Now that my hearing is corrected with HA’s if I use the Android Hearing Test (Pro) app in Demo Mode and test my frequency response, it ought to be pretty flat and sensitive to all frequencies across the spectrum in the test. In the low to mid-frequencies (100 to ~4000 Hz), it is but I have trouble hearing the high frequencies streaming the test to my HA’s. Before hearing correction, when I did the test with various earbuds and headphones and even my Note 8 phone speaker, the general shape of the curve generated more or less mirrored my high-frequency ski slope loss.
Well, I thought. Maybe there is something wrong with the app, my phone, the streamer, in the message “generate a high frequency tone of XYZ Hz.” So I also have the Android app Tone Generator Pro and I can step through various frequencies streaming to my HA’s and hear a tone up to 8,000 Hz in that in both HA’s but I do have to turn up the volume a bit on the phone relative to lower frequencies.
The main reason for this post, as I was doing the above, I was wondering, “Hmm? Can I blow out my receivers monkeying around like this or do the HA’s have some built-in protection against doing this?”
The other thing I was interested was with my high-frequency hearing loss, if the Hearing Test Pro Android app were somewhat accurately reflecting my HA correction, does an audi typically restore frequency response to a “flat” line or given my high-frequency deficit, to hear the softest high-frequency sounds, I’d have to have a dangerous high-frequency amplification, therefore I’m at the point where I can hear strong to loud sounds at the very highest frequency but not the softest?
And lastly, REM’s aside, if I opted for the DIY software just to monitor my HA performance myself, is it likely that that would give me a much better, more accurate relative frequency response curve than I would get fooling around with any phone app. I was thinking, too, as I learn to use the HA’s, it would give me some feedback on how well I have inserted the domes into each ear, how well I am keeping each receiver clean or whether I’m degrading my receivers, microphones, etc., by my treatment.
Final uncertainty! I have some El Cheapo microtool attachments for my canister vacuum. To avoid too powerful a suction in the microtool, I can let a lot of air into the vacuum by the suction control ports, etc. My audi seemed to think that if I were careful, I could use the microtool to clean my HA’s, the microphones, etc., with gentle suction - I’m wondering about the domes, too! Would love to hear about anyone who’s tried this and knows whether I’m heading for potential disaster!
