I have no interest or ability to build surgical implants. Purely over you skin. I've read about people with hearing damage loving bone conduction over regular headphones. It's been described as miraculous by some. Obviously hearing loss is complex and that's not for everyone. What is the grinder community? I assume not the gay dating app, I don't think that has a scene for cyberpunk body mod, but I could be wrong. I…

I'm referring to grinder / transhumanist / biohacking communities https://en.wikipedia.org/wiki/Grinder_(biohacking) Personally, I've been a member of https://biohack.me since more or less its inception but I have yet to undergo any surgery. That will change soon, and transducer earphones are second on my list. Hence my questions, I love to compare notes.

Can you point me at information about these subdermal transducers you're looking at installing in your head? That sounds insane, but I kind of want some.

The general consensus, after much experimentation, is that the targus isn't the best site because it just doesn't conduct loudly enough. Direct bone conduction via surgery of course works well, but then there is still the issue of power and amplification.

There's been talk in the past about a non-permanent dermal retainer that could do the same thing, and this could potentially be an all-inclusive package if done correctly. That's something I'd like to look into when I have the tools and money.

The targus and the temple are totally mid and high range. Try putting a 20W amped transducer on your jaw below your earlobe. You get VERY immersive sound. I see no way the targus implant could be worth it. I also don't see a way to put an implant on the jaw that would work because it's moving.

The spread between mid/high on the temple/targus and mid/low on the jaw are crazy though. When you have both it is full imaging that includes a space with a frustum inside your head.

Thanks for the body mod info! If you are looking at the implants I would highly suggest tying these positions I'm suggesting. I don't think it's worth the risk for the output!

Correct. At 30 Hz directionality is a pipe dream.

It's relatively trivial to find direction of the 30 Hz sound source, given 1 million budget - you just need to place microphones 11 meters apart and raise them above buildings until you get direct line of sight to the main source.

That's an example of how poor directonality is at 30 Hz.
