               | In this case, I agree that your earlier post exaggerates

               | 
               | For example, [1] quotes a top price of $3500/ear. That
               | makes $7000 total. A page full of search results [2] will
               | tell you that prices are in ranges like $1-6k each. Even

             | Hey, there's _dozens_ of us! :P
             | 
             | I wrote about my experience with this last year:
             | https://news.ycombinator.com/item?id=35897515
             | 
             | I did exactly the type of diagnosis you're talking about.
             | It was quite good at how it simulated a noisy environment
             | with a bunch of background chatter and then a single voice
             | you were meant to listen to that would repeat various
             | patterns of words with various combinations of lower
             | speaking volume and/or higher background noise.
             | 
             | One thing I wish I'd made a point of at the time was the
             | fact that, despite being an apparently soundproof booth
             | with headphones on, I could definitely hear people talking
             | in the waiting room and another audiologist in an adjacent
             | room. Though I'm not sure it would have materially changed
             | their lack of diagnosis (they'd already detected I could
             | hear into negative decibels).
             | 
             | I still don't have a diagnosis, but I'm increasingly coming
             | around to the idea that maybe it's not that my hearing is
             | bad but that I actually hear _too much_. What I 'd
             | previously thought was my unability to hear people speaking
             | on the radio in the car when everyone else clearly could
             | wasn't because I couldn't hear the radio, it's that I can't
             | hear it over the top of all the tyre and wind noise I'm
             | also hearing and trying to process out. I don't think the
             | other passengers in the car hear the rest of the noise,
             | they only hear the radio.
             | 
             | I bought various types of Loop earplugs and have found them
             | fantastic for live music events. I can now hear my friends
             | when they're talking to me! Unfortunately they greatly
             | amplify my perception of the volume of my own voice when I
             | talk which has the undesirable side-effect of making me
             | talk even quieter so I feel like I'm having to yell when I
             | want to talk to people. I've also not found them as useful
             | as I'd hoped in restaurant-type settings.

               | (Also, a PSA: if someone who didn't hear you says,

           | Couple takeaways I remember:
           | 
           | - "Silence is the new luxury" -- restaurants can have good
           | sound design, but it doesn't come cheap. Upscale restaurants
           | are starting to differentiate themselves with sound design
           | 
           | - The modern clean aesthetic (glass, concrete, stainless
           | steel, minimalism) promotes loud, echo'ey spaces
           | 
           | - "You're not having a good time unless your ears are
           | ringing" was an intentional design choice popularized by some
           | restaurant guru in the 90's. Growing awareness of the
           | problems is starting to create a backlash
           | 
           | - Loud restaurants are damaging for the waitstaff's health.
           | You can work for hours in an environment so loud that OSHA
           | would demand hearing protection.
           | 
           | - The luxury sound design studios can be so good at isolating
           | ambient noise that they also sell an "anti-noise-cancelling"
           | sound system that actually selectively re-amplifies crowd
           | noise for when you do want to tune up some sense of busy-ness
           | (with too much sound dampening in an unfilled room, it starts
           | to feel too isolated... being "out and about" is some of the
           | reason people go out dining)

               | That's why you'll usually find people who've worked in

           | Have you ever heard of Berard AIT (Auditory Integration

           | the sound therapies called "Hearing Equals Behavior: Updated
           | and Expanded."
           | 
           | There's a non-standard audiogram to check for imbalances in
           | the hearing. The standard audiogram is they just pick say 30
           | Dbs volume and check various frequencies in each ear at that
           | frequency, and if you can hear that - then "great!" The non-
           | standard audiogram checking for imbalances checks for HOW
           | LOW-QUIET of a sound you can hear at different frequencies,
           | and interestingly, with 100% accuracy you can predict a set
           | of behaviours that a person will have if they have an
           | imbalance at certain frequencies like 1000 Hz; not all
           | frequencies have associated behaviours with them.
           | 
           | An example of an imbalance would be if at 1000 Hz in your
           | left ear the lowest sound you could hear was 15 Dbs, but in
           | right ear you could hear at 10 Dbs - an imbalance of 5 Dbs,
           | but where the idea is that the body-brain-mind is a system of
           | finding homeostasis and equilibrium, so it should be able to
           | have it so sounds are heard at the same level - evenly, save
           | for actual physical damage. This is just a simple example and
           | there can be high peaks and valleys that show up in the non-
           | standard audiogram.

           | I have a similar story as yours. My issues with sound were
           | almost identified in Grade 2 when going from a kindergarten
           | setting, where there were no real performance or attention
           | expectations, to Grade 2. The teacher noted I was having
           | trouble paying attention. They thought maybe I had hearing
           | issues, it was a private school and so they brought in an
           | audiologist. My hearing was fantastic! So indeed,
           | unfortunately, 30+ years ago especially they didn't consider
           | that my hearing could be " _too good_ " - where sound was
           | overwhelming me; so I was hypersensitive to sound, arguably
           | hyposensitive to touch and other senses, and it was
           | medications in my late teens and early 20s that caused my
           | hearing to get super hypersensitive - to the point where I
           | was in what I consider a torture state for 8 months - where
           | even the sound of blinking was painful, or at least that was
           | the sensory I was associating the pain with - until I was

       | I think we probably need more rich tech billionaires to get
       | affected to attract large funding.
       | 
       | What billionaires that you know are affected besides:
       | 
       | - Brad Jacobs
       | 
       | - Ryan from Flexport/Founders Fund
