Not obviously related to the article, but given this might attract the hearing-curious or knowledgeable. For as long as I can remember I've had great difficulty hearing in noisy environments. In my younger years it didn't bother me too much as I was mostly at noisy events to enjoy the music anywhere, and if I wanted to talk we'd move somewhere quieter. If I make a concerted effort I can usually hear someone directly…

ADHD and APD go hand in hand.

Earlier quoted context omitted.

Big country, "louder is better", teens blasting their hearing with in-ears, concerts that leave your ears ringing for days, inadequate safety in the workplace, heavy use of drugs like Viagra (yes, hearing loss and tinnitus are a side effect in some users with high blood pressure). Diet-related hearing loss too as a lot of people eat crap. Probably other reasons too.

> heavy use of drugs like Viagra (yes, hearing loss and tinnitus are a side effect in some users with high blood pressure) Oh wow. The Manga/Anime trope of male characters spontaneously bleeding from the nose when they get er... excited might actually have some real world examples. Pretty sure "bleeding from the nose and ears" would kill the mood completely though. For most of the population anyway. ;)

Anecdote: Sudafed used to actually make my dad's nose bleed, but not just internally, from the external pores of the nose, and from the backs of his hands in terms of pores.

I have tinnitus, which is pretty annoying. Very excited to see the possibility of treatment for this.

I’d love to know what silence is like.

Same. Doesn't bother me at all, it's just background noise, but it's not true silence.

I’m really tired and based on the headline I thought scientists had a cure for male pattern baldness and the new hairs increased your sense of hearing…

Serious question from the article though…why do Americans account for an outsized percentage of hearing loss sufferers?

Selection bias, more access to hearing tests, solutions, awareness. In developing countries like mine, we simply have to speak louder.

Heh Heh Heh

If it wasn't dangerous, that could be useful in some situations.

ie. "I really don't feel like working hard today", so takes some Sudafed and gets on a Zoom/Teams call with work colleagues. ;D

Would probably only work once per employer though...

Well, actually, true silence (as in an anechoic chamber) can be maddening.

True silence makes people to experience auditory hallucinations usually. So like tinnitus, but I guess less predictable, and less consistent

Is this similar to the abandoned[1] program by Frequency Therapeutics?

> The FX 322 gel contains drugs that early studies indicate helped to aid new hair cell formation. These are called progenitor cells, which are unable to evolve into any body tissue. Instead, they are usually more inclined to develop into cells near where they are found in the body. > This particular drug encourages them to grow into stereocilia, which are hair-like cells in your ears that detect sound. Hearing loss is when these hair cells are irreversibly damaged, as they cannot repair themselves.

Some generators on https://mynoise.net/ have strong anecdotal evidence of at least temporary clearing of tinnitus. There's even https://mynoise.net/Albums/view.php?album=TinnitusRelief

YMMV.
