As a mid-50 year old who discovered two years ago that he has moderate hearing loss (50-55 dB HL), I will be forever grateful to Apple for doing this.

If anybody from the accessibility teams is reading this, please know that it is difficult for me to overstate my gratitude and my appreciation for the amount of work this must've taken.

Music sounds unbelievably better through my AirPod pros, and I didn't even know what I had lost until I heard it again.

I'm willing to bet that a lot of my middle aged compatriots don't even know how much their hearing has degraded… Get your hearing test tested, folks, while you still have it!

Yes, and protect your hearing while you can. Turn down your tunes.

Disclosure: Working musician. I wear musician's earplugs when playing in bands.

Totally agree but there's a small caveat...

Everybody has vastly different sensitivities to sound exposure.

Even identical twins with identical sound exposures can have drastically different hearing profiles especially as they age.

I actually have always been very careful with my hearing; there is some evidence that I may have a very very mild congenital birth defect that makes me prone to hearing loss, but that's largely speculation.

My wife is actually older than me and has a spectacularly sensitive hearing - as does her mother! - and she's the drummer! (The wife, not her mother :-) I just do keys and vocals...)

That's why it's so important that everyone protect their hearing because even though it's not too loud for the people around you, it might be too loud for you - and you won't know until it's too late.

Hearing being a "logarithmic" sense and decibels make this a bit weird to me. Like losing 6 dB of hearing in a car crash is considered negligible and insignificant, but that actually means the ears lost half their sensitivity in a flash (and it's never coming back, just like teeth). Likewise your 50 dB hearing loss is considered moderate, but actually represents a 300-fold reduction in acuity.

Exactly!

Although I try not to think about that too hard because... well it's kind of depressing.

But it's the exact reason that hearing aids are so difficult to design.

For example if you were to naïvely try to just "add back" 50 dB of gain to a 70 dB ambient sound, that hearing aid would be trying to pump 120 dB of sound energy into your ear canal... which would actually cause damage to the surrounding cochlear bands...

But if it doesn't try to add something there, then everything sounds distorted because you have way too much sound energy from the other frequency bands, perhaps ones where you have much higher sensitivity.

Hence the multi band compression and why it's so difficult, and why hearing aid manufacturers focus on speech intelligibility above and beyond everything.
