I’m curious about this too. Maybe they are listening with headphones? I have no idea if they make them like this but it seems like an opportunity for white noise machine makers to just add Bluetooth and they would sell more. Maybe?
White noise is literally random numbers. Your machine can do it using approximately zero percent of its available resources.
In a very real sense, any single transistor can do it, and computer engineering is an effort to keep them from doing it.

But why would I buy a machine for that when I already have a machine that can make any noise?

I’ve never had any of these problems personally. Not that I have anything against white noise machines but that’s why people see them as superfluous. They kind of are.
But maybe if you have spotty internet that makes sense.

Wow you are right that is hidden. I have an iPhone and had no idea that was there. I’ll have to try it out.
Sometimes I play rain/storm sounds I’ve downloaded from YouTube. Other times I use the iPhone white noise generator. I’ve set up 2 Siri shortcuts (one for sound on and one for sound off), but tapping the back sounds like a good way to do it, too.

There are apps that can make white noise while using 0 network really. If I was Spotify I’d write a library into the app that detected white noise and stopped streaming, and just turned on the local generator in their app.
I’d have a Javascript one-liner producing white noise, except web audio is a Gordian knot of inscrutable identical-sounding types and contexts and maps and whateverthefuck. Documentation reads like they forgot to implement it and hoped nobody would notice.
How do you generate noise? Well you need a sink. How do I get a sink? Well you need an event. How do you get an event? Well you need a processor. How do you get a processor? Well you need a context. How do you get a context? Well you need a node. How do you get a node? Well you need a sink. I’m going to stab you now. Understandable.
Anyway it’s something like
data:text/html,{script} ac = new AudioContext(); wn = ac.createScriptProcessor( 4096, 1, 1 ); wn.onaudioprocess = (e) => e.outputBuffer.getChannelData(0).forEach( (v,i,a) => a[i] = Math.random() ); wn.connect( ac.destination ); {/script}except with whatever dark wizardry makes output reach a speaker.Also I’m not sure .forEach works on whichever array-like type was chosen for audio channels. This stupid language has so many incompatible and incomplete array implementations.
edit: And angle brackets on script and /script, because this stupid website fucked up its Markdown. Preventing random HTML strings in comments: excellent, necessary, obvious; it is not 1999 anymore. Doing so by deleting the entire goddamn thing as if you parsed it before removing it: DEEPLY TROUBLING.
