12 kHz

Putting this into perspective:

There are no "high notes" above 12K. That's overtone/harmonic territory.

Without going to open a book or look at a keyboard, I think the top note on a piano is about 4K. I'm not aware of any other acoustic instruments which produce a note higher than that.

So, you're not missing any upper notes, but you're missing the very highest overtones.

With regard to overtones... The difference between 12K and 18K is not a lot, except for some finesse and detail. 12K is approximately an F#, and 18K is approximately the C# above it, so you're looking at about a musical fifth, which, at those frequencies and for ALL playable notes, amounts to a couple of additional overtones at very low output levels.

So I wouldn't get hearing aids to compensate for that.

However, I suspect that, since you're noticing things sounding "duller", that your hearing loss is more significant than you think, maybe even as low as 5-6K I'm sad to say. Or, you could have a notch or two somewhere, due to lifestyle or work-related activity. An otologist will be able to diagnose your condition and make a recommendation.

Do you have difficulty listening to a person in a noisy environment such as a restaurant?
