My neighbor's dog loves barking super loud at 5am, so I played him this lullaby and he went right back to his doggy bed. Thanks guys!

Bluetooth speaker on the porch and unpause when the neighbors dogs get barky... This is awesome

This made me realizing how silence high frequency can distort perception

[landres]

if your neighbors dogs wont let you them cry. Man, 10 hours? theyre gonna suffer. THANKS

[SCY]

This is the only thing that makes my neighbors beagle stop barking. I love dogs, but I have work to do. Cheers.

If you are unable to hear this tone, don’t be alarmed, it doesn’t mean you’re incapable of hearing it. Many speakers are incapable of reproducing sounds of this frequency. Some of you genuinely are unable to hear this, but others are only unable to hear it because their speakers can’t make this sound

Can't hear 20khz sound any more but I can hear 20khz tinnitus! If I could go back in time I'd tell my younger self to wear earplugs to those AC/DC and Motorhead shows!

[autoturret]

this sound makes my feet tingle
this sound makes my wrist sting
this sound makes my hips throb
this sound makes my ears scream

[marites]

I can totally hear my laptop Fan noises and I love playing this noise in public lel

[Samlerpill]

This is akin to the noise I get when I’m focusing. Like the euphoria fizzles that come from trying to survive a fearful situation…not quite but it’s the same sound. I can hardly hear it. But my ear drums perceive it

[Bolaceleste]

My ears:why is my phone not sounding?
My phone: sorry i have bad speakers

[ellamation]

I needed to turn up my volume to hear it clearly.

I knew it!
If you record this video.
Here’s the steps.
1. Record this video
2. Go to kinemaster
3. Extract audio
4. Duplicate over above 21 times
5. Put all EQ To voice
6. Put growl in voice changer
7. Check the auto volume
8. Put at 200% and also the volume envelope
Then.
I can now hear the 20khz audio.
It was still very high pitched even if you lowered the pitch.
More louder if you’re getting longer the video.
It increases the volume in every random per seconds a bit.
So you can heard the glitched sound, flashbang sound, Fireworks, and air sounds.

The neighbor's delinquent kids are going to love this.

There was a test done on this frequency used (on humans) for improving depression. There was a noticeable difference. Oh and BTW they did NOT run it for 10 hours! Just a few minutes.

The wonder boom 2 works.
