From Norman Doidge's book "The Brain That Changes Itself", I learned that: Long term white noise exposure might be associated with hearing loss, especially age-related. The theory was that "nerves that fire together, wire together", too much white noise compared to clear sounds will cause the neural mapping for sounds to gradually become fuzzier, making distinctions between sounds will become harder.

On the subject of hearing loss, can I plug my idea again that all devices should have a "constantly gradually decrease volume" option? It's way to easy to turn up a device for a temporary reason and then an hour later you realize the sound has been way too loud for a long time. I would rather push a button to turn up the volume twice an hour than realize I've been damaging my hearing for the last hour for something I…

I found myself particularly fond of this idea after reading your comment. Buttons840 I like that idea, you have my vote.

Interesting, could it be possible to elaborate which listening device you are using?

Not OP but I use one called LectroFan. They also have a small travel-sized one that doubles as a bluetooth speaker. It has revolutionized my ability to sleep while traveling.

I have the same make. I really like the lower range noise for blocking out stuff. I didn't notice any sort of bluthooth speaker ability. I might have to RTFM. That'd be useful.

I'm skeptical about generalizing those results to more "natural" sounds like fan noise. As others have mentioned true white noise is very unnatural due to its uniform power spectrum. Pink and brown noise though seem more natural due to the dampening at higher frequencies, and I'd bet things like fan noise, rainfall, waterfall, etc. lie somewhere along the 1/f^alpha for alpha > 1 (in between pink and brown). I'm sure…

Nature sounds like rainfall & ocean waves vary a lot I imagine, with lots of breaks and pauses, the lack of a continuous sound probably helps. A fan that's rotating back and forth might produce neurologically better sounds, as the breeze bounces off different parts of the room than one that is fixed in one direction?

Actually hm I just tried a hearing test at https://hearingtest.online (very well done site, read the sidebar notes) and I seem to have a characteristic 4khz dip. I don't listen to music with headphones and have never gone to concerts, perhaps the years of fan noise at night did indeed contribute to this.

IIRC compassion is acheivable on a bass guitar. Doodling improves memory retention / learning, too. IDK how much difference the content of a doodle makes?

Regarding doodling, it seems that any active productive study method is at least somewhat beneficial. I've found this in my own personal experiments. For example, testing myself with cloze deletions, creating Anki cards, generating mind maps, Cornell notes, inline annotation/marginalia, doodling, generating questions, generating mnemonics, mind palaces, etc. An interesting one is reading and reciting out loud: https:…

Awesome. Thanks for the resources. Coincidentally, I stumbled on this research today on the effect of exercise + meditation on word recall: https://hpp.tbzmed.ac.ir/PDF/hpp-9-314.pdf
