Audiology test results stuns me!

Just got back from a test on my hearing for my tinnitus and even tho the tinnitus worsened since it began (a year ago) I kept my hearing intact ! F YEAH. Have 100% on speech recognition at 40dB ( kind of yeah! no? .) Even have a better than usual hearing for sounds exceeding 9khz ( like a boss I'm quite proud of it ) than she ask me if I listen to bass heavy music so I say I listen to drum and bass/dubstep most of the time.So she says I have trouble with sounds below 500hz compared to the average even if not a big problem I am below average so I cried a little inside :(. And finally my ears are unbalanced with the left ear hearing better. 

And I learned new things about low frequency sounds. Because I was curious I asked if those sounds would damage hearing more than other and it turns out that those frequency act differently from the higher ones.

Mids sounds have 2 things to measure their possible damage. The dB level and the exposure (time spent hearing them).

Bass sounds have 3 things. The dB , the exposure and the vibration they can create ( exemple a boomy headphone with synthesized bass that makes you feel it.) and to the same level of dB when exposed to the vibration of those Bass they damage faster than normal mids and highs sounds. it's like instead of walking on some grass you stomp on them.

Then the highs are just painful faster.

I wish I could completely understand the graph she gave me afterward. Cause it measures a lot more than I thought . the mobility of the eardrum the space in the inner ear and a couple of other thing I can't comprehend .

And oddly enough I kind of like how this jobs looks like so I kind of see it as a possible career for me it just needs a master degree even. + having someone to treat you with the same problem you have really could benefit for tinnitus as he could know what you feel. Interesting stuff and all since I love the subject. 

I'm happy my hearing didn't worsen I feel a little better than before since I thought I was deaf but it's just the sound in my head that's masking some others and making it hard to hear in noisy places.

For the soundstage question for my ears .

Yes I have less accurate soundstage more noticeably for singers it's not centered I hear them a bit to my left (like just a bit in the left inside my head.) when i use headphone and I'm sometimes confused when someone call me from behind ( has my drop are in the 1khz-2khz and 4-7khz.) could be my headphone for music tho but I don't think so but it's not that distracting.

I'll show you the test results sheet she gave me ( there's french on it but it's a general explication of my hearing ).

They test the nerve reflex to loud sounds  to see if it protects the ears correctly unfortunately my left ear have inconsistent protection against loud 500hz to 2000hz sounds it's the inverse of hyperacusis well hypoacusis i suppose. So my nerve react incorrectly to loud sounds between 1-6khz and may or may not protect it against 100dB+ sounds. There's a lot of things I can't understand. like daPa and mmho.

Also if you go for a test right after it it seems to worsen but it's just you concentrating on it more on the sounds you hear. And when in the chamber with the headphones on ( they had seenheiser headphones but I don't remember the name. they had brown earcups for all I know. ) My head became a maze of sounds it was far from being silent lol but white noise did effectively make them all disappear for a couple of minute and I was hysterical almost when I heard silence for the first time since a year.

In the graph when you go lower on it it's worse hearing it's in the +dB if you go to the top of the graph it's -dB so my peak at 9khz is where I hear the best with drops in the bass and in the 1-6Khz for the left hear :(

Well the audiologist showed me and told me so. But they are not all consistent some said they couldn't damage any other cells while others says it damage every cells in it's path while getting to the one making this special frequencies. Yeah dB is a vibration but the bass ones are more powerful. I don't want to argue when even among themselves they can't be sure of whether it damage faster or not.

I would say bass are more damaging since it has to reach far inside the Cochlea. And I don't know at what frequency she put the sound she made a earphone doing but it was basically a vibrator in my hand but it was to small to be audible. maybe she talked about the power of those wave sounds.

I wonder why my ears are so unbalanced compared to test like those. Could it be my job. cause I have a strap carrying stuff all the time to my right making more sounds and having things hitting it all the time then my left ear have 7/8 hours a day. I'll go back to the first clinic I went some months ago to ask them the test I did to compare if my ears were balanced at that time.
