DIY Parabolic Microphone ~ LISTEN IN 300+ FEET AWAY!
HTML-код
- Опубликовано: 29 май 2023
- Check out this demonstration of my fully tweaked, and super sensitive homemade parabolic microphone. Also learn how you can make one. You'll be amazed by how well it works and the incredible range. Under ideal conditions(light or no wind, and no other noises), the range will easily exceed what you'll see in this video. Enjoy the video!

Terrific thumbnail and thanks for another great video!
Oh project farm in the house 🤙
2 of my favorite Utubers!
Aw Project Farm here too!
A few decades ago there was one in the Science Museum in Saint Paul, MN and it was shocking how well it worked. I suspect that listening to private conversations of other visitors eventually became untenable.
Awesome demonstration!
Glad you like the video! Be sure to share with others. Thank you
thanks for another great video
This would be fantastic for hunting, out where there are no cars, no roads ... you'd be able to hear deer walking around, hear how it amplifies the ambient or 'background" noise. That's Impressive.
When you walk you can hear loud crunching on the ground.
That was like a hundred years ago! You haven’t aged a bit my man! Thanks for the content.
Amazing diy
Good job , LIKE
Pretty cool. I could barely hear the talking when you were close to the player at first, and couldn't hear it at either distance, but I have a hearing loss, so I'll take your word for it. I used to build DIY projects like that years ago. I built a windshield wiper variable delay from a magazine design for a little '85 Dodge RAM D150 that only had 2-speeds and off. I bought a cruise control for it from JC Whitney and installed it. I designed my own car alarm system for an '82 Oldsmobile Cutlass. I've built all kinds of things from electronics projects magazines, but I tend to buy products that I want and need now instead of building them. I still try to repair everything I can and am usually successful at it, be it electrical, electronic, mechanical, etc. Persistence and determination are key, just like you making improvements on this project.
I wonder if other things for the parabolic bowl would be more efficient and/or cleaner. Maybe insulate the outer metal with something because it's rather thin. Extending the bowl with cardboard or something may help block the wind and background noises from the sides. A true parabola shape might help, too. Even still, great job, Scott! Just sharing thoughts.
I did make one of those back in the day. Stereo with both internal and external microphone 🎤 it's a pretty cool device, but I never found a nice enough parabolic dish for the reflector part. An old metal lampshade was not quite good enough. 😊
I was lucky to find a metallic dish that had a flat bottom that I hammered out. Thanks for watching!

Nice 🎉
That's awesome, what is it like listening if pointed at a window with other people talking behind it?
@shangex4795 🤣
Altoids can?
It looks like a perfect case for a guitar distortion pedal or preamp!
I have some questions about the microphones used in parabolic microphones, instead of using lavalier mics would it increase volume input with a shotgun mic or a condenser mic or would this decrease its performance?
While shotgun microphones are great for direct sound capture, in a parabolic microphone setup, an omnidirectional microphone is typically preferred because it's better suited to capture the focused sound delivered by the parabola. The parabolic reflector essentially replaces the directional function of a shotgun microphone. 😊
When using a police scanner no longer trips your trigger...lol

What happens when you process the audio through one of the new noise cancellation applications such as NVIDIA RTX Voice?
I use Audacity to remove noise I do not want, which makes it much easier to hear what you're targeting.
A good source for a parabolic reflector is a 1950s type electric heater with the coiled element removed.
Yes!
Please, could I have the instuctions? Is awesome!
Click the video link thumbnail at the end of the video
Where is the mentioned link?
Where’s the link to learn how to build it
would a small satellite dish work too?
too bad you cant make it focus on the specific point of noise.
Yes. If the mics are properly positioned
Unable to locate the link for making this.
It's a video thumbnail at the very end of the video you can't miss it.
I want to buy it how much?
I can't see the link to the making of video.
How can you miss it? Clearly you left the video before it was done.
I'm on the phone and it's not showing
Now, do it the other way and make a long distance sound thrower 🤔🤔
Or acquire an ultrasonic listening device & use it with your parabolic reflector.
I have a really nice handheld digital recorder and I have a condenser mic as well as a few dynamic mics. I'd rather make one and buy a generic $50 piece of junk 😊

Great for guys who are creepy and frugal 😂
Couldn't hear a thing.
I heard nothing thought we were going sample a real conversation not static and maybe a cricket or two.
Wow if you couldn't hear anything, then you better get your hearing checked.
Creepy for creeps
Leave your wife and me alone we tryna talk!
LOL
If you do the correct math and make a less deep and more wide dish it works much better
that's crap
