I want to be able to do that too, like this one for instance
PURE 0.33 Hz EPSILON BINAURAL BEATS | Epsilon Waves | Reality Shifting ⚡️
It would be great to be able to produce any arbitrary Hz pure tone or whatever that example is
Like 0.165Hz or anything
You wouldn’t hear it even if it was. Your speakers may not be able to output it either.
Did you watch it? What do you think it is or what do you make of it?
Hear for yourself? It does sound very low tho, like rumbly and relaxing. I definitely hear it as well as feel it so lets take that off the table
Except your speakers can’t produce the sound and even if they could your ears can’t hear it.
But what is it then (in your estimation)?
Human hearing range is 20hz to 20kHz. That you can hear it doesnt mean that you can hear “0.33hz”, more likely that its not actually that frequency.
I can hear that video, but using a tone generator, I can only hear clicks and pops from my phones speakers. So it’s probably lying about its frequency.

YouTube compression will remove inaudible sound ranges anyway, so they probably had to fake something for it to make a sound at all.
As residentoflaniakea@discuss.tchncs.de pointed out, its 98hz. Still low, but not 0.33hz.
Ohhh now that one is interesting. I actually can hear it set to 1hz, but its not 1hz that I am hearing. Rather a higher pitched whine that cycles at 1hz. Similar happens for other very low frequencies and changes the frequency of the whine. I presume it is my speakers struggling with playing very low frequencies.
Along with adjusting volume, every low frequency can be heard but it moves from hearing an actual low frequency to hearing the speakers movements and then really low it whines.
Are you perhaps hearing a 50/60hz signal from your electrical grid? If its higher, could possibly be frequency from your processor (or some other internal device) clock?
Those frequencies are well outside the usual working range of most amps and speakers, so its not surprising they dont work very well.
Clock speed of some kind of internal component perhaps, would be interesting if I had a way to measure it.

Might depend on your phones microphone quality
Your speaker would be vibrating at ⅓ cycle per second at that frequency. You literally cannot hear it. Your speakers will compensate for this by playing an enharmonic series of overtones to trick your ears into “hearing” it. Chances are there’s a low-pass cutoff in your speakers well above that frequency to prevent damage.
hi, most people can hear as low as 20hz most big speakers can produce sounds in the 30-50 hz range. smaller speakers can usually only produce higher frequencies. it’s different with headphones, but you can check the specs for your hardware online, mostly from the manufacturer or testing sites.
This sound can be heard from my smartphone speaker, which definitely can’t play low sub bass frequencies. and it sounds pretty high as well. maybe 100hz or something? can’t say for sure. can’t check on my PC right now, might come back to it later.
-edit- try this site for tone generation: https://www.szynalski.com/tone-generator/ it should help understand the sounds of frequencies a little better!
So lower frequency requires a larger speaker because of the larger wave length. 1000Hz is 13.5 inches. 0.33Hz is 3424 inches. I doubt your speaker is that big.
