So I recently had a hearing test and came back pleasantly surprised. My hearing upto 2K looks pretty good, dips down between 3K-6K (about 20 ...somethings, although it's not marked as dB, that would surely make sense) and then is back to normal by 8K. The suggestion is that I have 'mild' hearing loss in those freq's but my hearing relative to the rest of the world in those freq's is only down a little - ie I have above average hearing in the other frquencies
It's prompted a bit of thinking and maybe an experiment or two...
1) trying to eq to my hearing loss. I should objectively then be perceiving flat frequency response, however my brain will be used to my own weird ear eq and I would expect it to sound bad.
Might be a fun experiment though!
2) finding what music has most of it's content in those frequencies. I listen to all sorts of stuff from Jazz to Rock to Blues to more recent electronica, and I have no idea where the content of that sort of music sits in a frequency range. I'm assuming it's where I've lost hearing as I worked in a lot of bars and managed a live music venue for a while...
3) seeing if I enjoy music who that doesn't center around those frequencies more (ie does 'more' stimulus = more enjoyment?)
Anyway, it does explain my liking for Nick Cave/Tom Waits/Howling wolf - those fellas all have deep voices and would be clearer to me...
Anyway, I was just thinking aloud; what do the collective brains trust of diyaudio have to say?😕

You should try the real impulse response step procedure on yourself
It's a little bit risky since 1 to 4 kV impulse is used but it lasts
less than a second.
If hands and arms are ground connected, the experiment is already failed.
If/when moving of a foot or leg is done at tempo, you'd be PRAT defined
Then you can pass to step two, at different angles

This brings up an interesting point .
Since hearing tests are done with head phones, the shape of the ear and how it can alter a perceived sound is largely eliminated .
However, when you listen to music normally (without headphones) the shape and protrusion of an ear can alter the sound we perceive .

Fair enough. I can see there may be a degree of freq dependent distortion due to your ear shape, however I can't think of a way to measure it 🙂 For the purposes of my experimentation I might just ignore that factor...
I'm holding off on trying anything until I find out what the mystery units used in the hearing test actually were. 🙂

Hearing tests are measured in DB HLm (hearing level).
It is slightly different that SPL.
No point trying to EQ to flat. Unless you developed the notch overnight to your brain your hearing is flat.
Normal hearing is from -10dB HL to +25dB HL.

Hi JRace,
thanks for the insight into the numbers on my report. I get that I'm 'perceiving' flat eq, and 'hearing' my notch eq, but the playing around with that is fun 🙂
So a question then - I'f I'm down 20 'units' at a freq, what would be the relationship between the SPL and HLm?
