Laser Microphone

At every moment, we are surrounded by thousands of sounds too quiet to hear: bubbles in water, the movement of an insect’s legs, a spider web blowing in the wind, sand falling in an hourglass. Objects oscillating with undetectable amplitudes are creating symphonies all around us that we are deaf to. How can we hear into these secret sonic landscapes and tune into the frequencies of the natural world? Laser Microphone is a new work from Kai Lab that amplifies microscopic acoustic events. Audio from Laser Microphone is as heard in the video.

i Love the idea and the closeup Foottage, i dont know why it has not more likes

[@shawnphillips4804]

This is amazing! Ok so it's a laser pointer that's pointed at a microphone. And the laser produces waves when the light gets broken from touching the microphone sensitivity. The bubbles are what's causing the light create tiny sound breaks in the beam and it creates that sound. Go look up laser lights being used to create sounds that mimic your voice and break into Alexa or Siri or Google products!

If instead of a laser we put an electromagnet what results can be achieved? In your experiment you can see that sound in the form of vibrations does not stop in front of a glass full of water. So it could work on masonry as well? Obviously by placing the laser and sensor (such as a photoresistor ..... ), on the light beam. I need to try it out.

good video performance, this video is underestimated. BUT, you could do more videos about optical sound processes.

[@davidegaruti2582]

this curius device uses the same mechanism as a photophone : on one side there is a laser , on the other a photocell that creates an electrical signal when illuminated , the electrical signal can get fed to a speaker and create the sound pattern we hear ... the original photophone by alexander gram bell could turn sound in light , and then light back into sound again ... this is the same working principle of a radio , since both light and radiowaves are electromagnetic waves , however it is indeed a lot more magical seeing it with visible light ...

How about a special light that CO2 (instead of other gases) breaks? Would that be a good pickup that's exclusively for aerophones? Tuesday, May 2, 2023 CE, 19:37 EDT

Great Work. Would like to know how it sounds if you would blow some smoke or dust through the laser beam.

[@kailab8666]

Smoke sounds like a gust of wind and dust sounds like granular noise :)

[@SlavaNesmeianov]

@@kailab8666 This doesn't count. PLEASE show us how it sounds like)

[@9z9z9z9]

Try sending sound from an earbud through the water medium.

[@neihardt091]

did you put eq on the sound to match the shots?

[@gustavoalberto8660]

Amazing!!

[@autenicpro8899]

The action lab brought me here

[@viejaspeliculasfilipinas3621]

Can you please list all materials needed? I wanna make one myself

[@anotherguy9402]

Photodiode

[@SuperJon8002]

Hey, what a amazing mix. Thanks for the video. Did you built that yourself or bought somewhere. Would love to have one as well

[@kailab8666]

Cheers ! Yes we built it ourselves :) Happy to make another one if you're interested

[@victorminces]

Love it!!

Laser battle!

[@hythu6816]

😳 wow

[@myyoutube6978]

Melton

[@БахаЖалгасов-ю6м]

Oh shit

[@L2GreekMafia]

Could you please share how it's done? Thank you!
