‘Audible enclaves’ could enable private listening without headphones. (www.psu.edu)

It may someday be possible to listen to a favorite podcast or song without disturbing the people around you, even without wearing headphones. In a new advancement in audio engineering, a team of researchers led by Yun Jing, professor of acoustics in the Penn State College of Engineering, has precisely narrowed where sound is perceived by creating localized pockets of sound zones, called audible enclaves. In an enclave, a listener can hear sound, while others standing nearby cannot, even if the people are in an enclosed space, like a vehicle, or standing directly in front of the audio source.

I've found that bone conducting headphones work well for this. They are even secure enough for running and climbing.

Especially if you attach them to your mastoid with a couple wood screws.

You'll actually want to use metal screws, as wood screws don't conduct the ultrasonic waves as well, since they're not as stiff

I've always been very curious about this technology, but I imagine that they wouldn't be as good at transmitting high frequencies. I'm no audio engineer so it's only a hunch of course. Do they sound comparable to a decent pair of buds in the ear?

Fuck no they don't sound good as regular headphones. They leak raw sound it. I've tried many major brands and the top devices. Plugins to bluetooth and more all best brands and models. It was thousands but worth it. I learned a lot about technology along the way.

I have Aftershokz, and for what they are, they're better than most of the in ear buds I tried. Better quality, cleaner sound.

They do high frequencies fine, it's low frequencies that they seem to struggle with, or at least, the ones I got do, but then again i did spend a lot less on them than on my over ear ones. They're about on par with in ear ones though.

I'd say so yeah. I switched between headphones a lot recently and they don't stand out. All headphones have their own sound anyway. I just embrace what they highlight and get to know my favourite songs again.

The ones I have have some speakers aimed at your ear to fill in that part, actually works really well. I can't stand the ear buds you physically insert into your ears, the rubber tipped ones, these have been good to replace my on ears for activity. Plus you can hear what's around you which is why my partner gifted me them.
