That’s an interesting product, I’ll check it out.
I HAVE SOME GOOD NEWS FOR ALL YOU KIND REPLIERS.
My only tool for investigating what’s going on in my ears (or rather my brain) has been my Sony WH-1000XM4 headphones. Thanks to a useful Android app I can perform extensive EQ, with a different EQ for each ear. This equalizer has 31 bands, not as accurate as a Parametric EQ but certainly a good way to investigate the matter.
I am quite sure to this day that my most affected frequencies are the relatively high treble frequencies, the magic number, to my assessment, is 8Khz. But also 6-7Khz and 9-10Khz seem problematic. I believe the worst sibilants are in this spectrum. Even though sibilance can even start at 3-4Khz.
So up till now all I did was destroy treble on my stereo speakers, and same on headphones.
While deadening treble does provide relief from some of the harshness, the sharp distorted sibilance is still prominent and drills my head.
So I found out a nice fact… Phone calls only deliver frequencies up to 3.3Khz. Phone calls through this process have been very forgiving on my ears. Perhaps the only way I can communicate with ease.
So I used the EQ to drastically reduce (around 20dB or more) high treble frequencies, but keep lower treble normal (2-3Khz). I then apply a big boost at around 1.5Khz, which is upper midrange. In addition boosted the midrange, around 400Hz,which is the area of fundamental voice frequencies.
The result is a muffled speech but fully understandable, the sharp sibilance is not only reduced but fades quite a bit because of the dominance the EQ is giving to the lower voice frequencies (400Hz & 1.5Khz).
So this works quite well on my headphones. But what about my speakers?
Well, I got a decide called MiniDSP 2x4 HD. This small device allows full control of a stereo system and includes a vast Parametric EQ.
I haven’t set it up yet, but if I can get a similar result to my headphones EQ, then we’ve got a breakthrough.
This does not solve the problem at its core, but if this allows me to have some comfort in my digital life, I’m all in.
The problem is not as severe in real life interaction anyway. It’s bad, but i wouldn’t call it torture.
I will report back as soon as I get the time to setup my MiniDSP.
Cheers to you all.
