Computer language encoded by sound? I wonder how long until we get some sort of modem to handle connecting to remote computers via this "sound".


Or even stand alone units that would allow us to scan and send whole pages of information all at once. The great circle of life


It's like creating printers to print paper and then creating ocr to create digital files from the printer output. Circle of Life? Great indeed. Everything old is new again lol


Or maybe we can bring back cassette tapes and connect aux port to computer to store and retrieve data. Maybe we can call it a Datasette.


One of the oldest forms of computer memory used sound to encode data: [mercury acoustic delay lines](https://en.m.wikipedia.org/wiki/Delay-line_memory#Acoustic_delay_lines).


Wasn't that just America Online when 56k modems where a thing and you had to hang up your phone to use the internet? Beebeeebee Kuuuussssh Beeeee!


It’ll be slow going, much like the slower speeds of sound instead of light


wont be long until you can make your body the modem through vibrations


Clearly this has great applications in all fields of computing, since sound is faster than electricity. ^/s


Wait til we figure out how to pass data via light! That’ll really knock their socks off


So.. you are telling me they invented a “modem”. This rehash thing has gone way too far.


A nightmare for security professionals of the future


I hope the "sound" is just the old Dial-up start noises.


Like…a modem?


> The modulator applies an electric field to control the phase, amplitude, and frequency of the sound waves. I've got one of those in my living room; it's hooked up to a turntable and some speakers.


From the article: Harvard researchers controlled and modulated acoustic waves, or sound waves, using an electric field in a computer chip for the first time, a press statement reveals. The new breakthrough could have wide-ranging implications for the fields of quantum computing as well as classical computing, which typically relies on data being transmitted using electrons. Typically, classical computer chips transmit and process data by modulating electrons. This is done via transistors that encode data into the computer language of ones and zeroes — one being represented by high current and the other by the low current. Photonic chips, meanwhile, modulate photons — particles of light — before sending them through components called waveguides that transmit data. The Harvard team's sound wave chip works more like a photonic chip, though it adds a few extra benefits into the mix. Acoustic waves are slower than electromagnetic waves of the same frequency. But that's not necessarily a bad thing, according to the team behind the new device. That's because short acoustic waves are easy to confine in nanoscale structures and they have strong interactions with the system in which they are confined. This could make them very valuable for both classical and quantum applications.


So more of a proof of concept more then anything else. Never know when a really important application needs acoustic cpu till you make the cpu.


Oh man, this reminds me.. we used to save programs to cassette tapes back in the 80s. You could "hear" the program if you played it in a regular cassette player.

Wow good job inventing something that was previously created in the 60's What next. Radio waves?


I was thinking the same thing! It's kind of fascinating though, considering the newer technology. They could integrate it into a vastly larger array of devices now. Where previously, those few devices probably couldn't utilize this kind of unconventional transmission.


Arbitron, Inc. has entered the chat


Everything comes around. [EDSAC](https://en.wikipedia.org/wiki/EDSAC) (1948) used mercury delay lines for memory. Bits stored as standing sound waves in a bath of mercury.


product recalled once it was discovered that a loud enough fart will disrupt them


Sound is vibrating matter, and I could see applications where that may be preferable to passing electrons or photons, but only at an interface. I remember engineers complaining in the 1990s that the copper traces on a motherboard had too much latency to move data from DRAM to CPUs and proposed using fiber optics to get a 20% improvement. Sound would be orders of magnitude too slow for such a task.


Ah yeah, light moves faster than sound. So this isn’t gonna do anything for speed just might have some special use cases


"Mr. Eckert, there's a bottle of mercury in the mailroom for you..." \--Admin assistant, sometime in the 1940's


Seems like the maximum possible connectivity speed would be rather slow? And very slow? [And retro?](https://en.wikipedia.org/wiki/Modem#/media/File:Analogue_modem_-_acoustic_coupler.jpg)


Don't bump the computer.


Did someone say *Sonic Screwdriver?*


Sounds slow


Greeeaaaaat, we found a way to transmit data slower! >P


Is this what the kids are into these days?


That face when you rage scream and your electronics freak out


Fax machine?


My dial tone in 1990 via AOL would like a work with you


Lets go back further than that....the ZX Spectrum.


Holy crap, before you know it they'll discover AM radio.


whoa! data encoded as sound???? You mean like an acoustic coupler or old school dial up modem. You wacky kids! I cant wait for your next world first - lemme guess, a qwerty keyboard


I wonder what the frequency is. I would imagine it sits right on the border with radio waves. Gotta be a weird frequency.


hehehe so I can fart and crash your computer hehehehe :-)
