doesn't sound too useful at first

2019-09-14 04:49:07 UTC  

now consider that all you're trying to do is eliminate all the noise, and that the noise is just vibrations, and that those vibrations exist everywhere

2019-09-14 04:50:09 UTC  

now, imagine you can take in all of those vibrations with a laser

2019-09-14 04:51:51 UTC  

and you can point that laser anywhere, and if you can reflect it back, you can process all of the vibrations, and if you figure out how to isolate only the vibrations from one voice, you hear what you want from simply pointing a laser

2019-09-14 04:52:55 UTC  

so even if they don't have a smart phone relaying everything they say

2019-09-14 04:53:30 UTC  

and even if they turn up loud music to drown out what they are saying

2019-09-14 04:54:57 UTC  

if you can bounce a laser off of a surface that is picking up the vibration of their voice, you can eliminate the noise and hear what they are saying

2019-09-14 04:58:05 UTC  

anyone want to take a guess at what technology research universities are persuing?

2019-09-14 04:59:36 UTC  

I had an idea like that once in a story, except that it was a pair of headphones that could selectively cancel out certain sounds so that if you and your friend were wearing them, you could have a quiet conversation and hear each other even at a rock concert.

2019-09-14 05:00:04 UTC  

we already have that

2019-09-14 05:00:13 UTC  

Really?

2019-09-14 05:00:32 UTC  

there's two options at least

2019-09-14 05:01:15 UTC  

one is just noise canceling headphones with voice coms

2019-09-14 05:01:29 UTC  

the other is what shoorters use

2019-09-14 05:01:37 UTC  

yeah

2019-09-14 05:02:19 UTC  

headphones that cancel noise outside of a certain range so you hear normal stuff but the gunshots get blocked out

2019-09-14 05:03:07 UTC  

Aren't the shooting headphones just insulated headphones that also have microphones on the outside, so it plays what it picks up, but mutes itself if the mic picks up something at a certain decibel level?

2019-09-14 05:03:23 UTC  

yeah

2019-09-14 05:03:39 UTC  

and you can just block everything and have voice

2019-09-14 05:03:47 UTC  

1XJV circuit.

2019-09-14 05:04:24 UTC  

but anything within the range still comes through

2019-09-14 05:04:37 UTC  

its just a matter of magnitude

2019-09-14 05:04:54 UTC  

Oh, I thought nothing went through when the high decibel noise was happening.

2019-09-14 05:05:02 UTC  

noise in the magnitude can still drown out anything else

2019-09-14 05:05:09 UTC  

Excuse me, *2JV* circuit.

2019-09-14 05:06:08 UTC  

yeah, that's all possible

2019-09-14 05:06:26 UTC  

it's just magnitude filtering

2019-09-14 05:06:42 UTC  

Interesting

2019-09-14 05:06:57 UTC  

frequency filtering is something else

2019-09-14 05:08:52 UTC  

multiple people speaking in the same frequencies

2019-09-14 05:09:14 UTC  

and plenty of noise there as well

2019-09-14 05:09:50 UTC  

doesn't exist

2019-09-14 05:11:19 UTC  

I'm telling you this because I'm working on it. If it existed, my job would be done.

2019-09-14 05:12:29 UTC  

at least two vantages to it

2019-09-14 05:12:49 UTC  

one, be able to separate the frequencies

2019-09-14 05:13:20 UTC  

two, be able to get the frequency in the first place

2019-09-14 05:13:33 UTC  

that's where the lasers come in

2019-09-14 05:14:32 UTC  

you can test this with microphones easily

2019-09-14 05:14:44 UTC  

that's the first part

2019-09-14 05:15:12 UTC  

record a bunch of stuff and figure out how to separate it

2019-09-14 05:15:53 UTC  

second, figure out how to do it without microphones
