I need 10 hours of this - sounds like a ship's engine...

[nikolasslead]

This is actually like ... so relaxing idk. Like a hug for my brain.

Fun fact: This frequency is the almost the same as a cat purring, it’s actually shown to have healing properties such as, release of endorphins, lowering blood pressure and it also soothes or eases mental illnesses

[ihavesubslol]

Just came here after finding out that this hertz makes your bones grow, as well as is the frequency of cat purrs.

With headphones it makes your head vibrant

Plug in your earphones!!! It's working!!! The note here is Ab 0 tuned -027. If you can play G 0 on a 448.98 hertz instrument, you should get 25 hertz. The four basic notes on the video is Ab -2, Ab -1, Ab 0, and Ab 1.
Ab -2: x.25 speed will give you 6.25 hertz. There are two parts to a wave: the crest and the trough. One up and down movement of the sine waveformed mechanical wave is a sine wave. 6.25 sine waves can fit into a second, so 6.25 hertz.
Ab -1: x.5 speed gives you 12.5 hertz. Infrasound is so low that our ears aren't sensitive to these frequencies. If you can perceive 12.5 hertz as Ab -1 (G -1 on a 448.98 hertz instrument), then you have good hearing.
Ab 0: normal gives you 25 hertz. This sound is so low that it is easier felt than heard. Plug in your headphones. If you hear G or A flat in Ab 0, you have good hearing.
Ab 1: also known as double bass A flat, x2 speed gives you 50 hertz. If you own a 448.98 hertz instrument, The note for you is G.

Good for breaking in sub drivers. Just be careful not to make mushrooms out of your voice coil formers. If you hear a tapping sound, you're hitting the back plate. Turn it down.

I real like a fan it blowing into my ears with this one

[lulublasz]

The lower range of my audition starts here. Fucking good playlist!

[jorgetheld]

18th and my iPhone headphones massage my eardrums

[dominikwylie]

the etruscan shrew has the same heartbeat as this as its 1500 bpm

[MrTasYT]

People keep saying relaxing, I played this on my 2 12s and I can no longer hear 🤣🤣🤣

[brookvillekansas]

If you ever have the opportunity lay under a piano while someone plays it. Amazing experience for vibration healing!

[Clarityinlife]

Oh 😲 wow 😲
2x speed is wonderful ✨😍✨😍
Adjust volume before speed changes

[jesuschrist]

i love controlling my headphone’s volume wheel to bass notes. its the only time i hear distortion from it

[misterklister]

25 Hz is almost the heart rate of the Etruscan shrew.

[vina]

The frequency in use prior to the standardization of 50 hz

[UnanimousDelivers]

I heard that this is the speed in which washing machines spin-dry your clothes (1500 rpm)
