I’m wondering these gain controls. There are different gains for “Loud”, “Moderate” and “Soft”. Are there any -range for “Loud” example ? Is it over 80 dB ? If I listen music rather loud (say 85-90 dB average), and gains are then according “Loud”, are highs (4-8 kHz) amplified only by 4-6 dB ?
Another question, above there are “1”, “2” and “3” tabs. I assume that they are for adaption steps, right ? If I select “3” it remains effective ?
Click Soft (45 ), Moderate (65 dB ) or Loud (80 dB SPL) to select controls at each input level for all frequency channels.
But even with this explanation, it’s not clear which range they’re talking about. Is “Soft” at up to 45 input? And “Loud” at 80 dB and above? Then what is “Moderate” being at 65 dB? Is it between 45 dB and 80 dB? Then why doesn’t it say that, but instead says 65 dB???
And yes, 1, 2, 3 is for the Adaptation steps. If you skip that and went straight to 3, then you can just ignore 1 and 2.
Thank you. I wonder why these gains aren’t somewhat linear, or are these just data points of linear gain ?
I find it odd that if you listen (music), at 79 db gain is 10 but at 80 dB gain is 6 dB, for example. That is big difference. I would imagine that sound pressure level varies in real life quite lot, therefore only three ”steps” in gain feel not sufficient.
There’s a lot of voodoo magic going on in terms of the fitting rationale employed -> what kind of equations they use to calculate the gain, then there are other considerations superimposed on it, like with the Oticon VAC+ rationale, if it’s a reverse ski slope loss, they buck the conventional wisdom of simply applying gain where there is loss, but they actually focus on more gains in the mids and some highs for better speech clarity even though the hearing loss is not heavy there. So it’s not possible to rationalize what the gain numbers should be if you’re not an insider withthe complete picture of the mathematical equations and special considerations used.
They never explain how they use the 45, 60 and 80 exactly, so you can’t really presume that Moderate is up to 79 and Loud starts immediately at 80 dB. Those might have been just nominal representative borderline values that might have been applied along with some sort of gradients between them and they’re not really step gains like you presume.
The best way to approach it is not to try to make sense out of the values or read too much into it, but instead just consider them as “handles” where you can tweak things and just let the magic occur.
It might have been why they were deliberately vague about quantifying what Soft, Moderate and Loud are, and eventually by now, they even removed the actual values from their online help. They probably just want people to see it as qualitative parameters and not quantitative parameters.
Right you are. There is somekind logic behind, that I don’t understand. Only way is testing with different values (with nominal changes) and try to hear if some effect.
