Pink noise

And Nate took so long to make this and it's a step-by-step guide of how to do this with just a measurement microphone.

Now, the only thing is that if you want to do it to the absolute, like, um nuance like making sure that like every kind of bass is covered then you really should buy an earthworks mic i can't remember what it's called it's terrible because i use it all the time um but there is an earthworks mic and they've got a certain calibration for it and they use the moving mic method so honestly my wrist gets sore when I'm doing it because like you move you do it and it's like you play Pink Noise and it's like fucking Wingardium Leviosa it's like fucking hell my wrist is fucking aching but that is a cheaper way of doing it it is laborious but like Nate said to me that you can do the moving mic method using what they've got in the PDF with say a Sonarworks mic which you know could or again like another maybe like a mini DSP USB mic and so it might only maybe cost you like 50 60 quid which is a lot lot lot lot cheaper it is manual but if you want to save money and basically get I would say maybe as good or better results and you know exactly what it is that's happening and you know exactly like basically you have to manually EQ everything and you use Room EQ Wizard Room EQ Wizard is the best free tool of all time for me it still baffles me how Room EQ Wizard is free it's it's yeah It could

easily be a

£1000 software, like Smart is.

Also do exercise, diet as well, all those things.

What's this thing about pink noise, listening to pink noise, Mike?

So pink noise, it just kind of sounds like the gentle static that you get on a radio.

And there was a recent study that showed that it basically took a load of healthy volunteers, like people in their 20s, and And got them to have a nap in an MRI scanner, which is a difficult thing to do.

And then they played them little bursts of this pink noise.

And what it seemed to do was to strengthen the slow brain waves, these waves of electrical activity that you get in non-REM sleep.

And that also seemed to increase the flow of cerebrospinal fluid into the brain.

But obviously, you do need flow into the brain in order to then have a flow out of the brain.

That's point A to point B. Um, the positive and the negative side, A and B, each have purpose.

I work with something called pink noise and brown noise.

Um, you can't hear those, but that is, um, uh, is what the brain naturally makes.

It's something called aperiodic noise or the one over F curve.

I'm always ready for one.

So I've got an interesting item here, that tiny bursts of pink noise may clean out toxic waste from the brain.

So do you know what pink noise is?

I know that noises have different colors.

Like, there's white noise-

Right.

But then there's-

Well, pink, pink noise is kind of staticky too.

You have to do like an acoustics report.

So we had to commission engineers to come in, play Pink Noise in the middle of the night.

What's Pink Noise? It's like a hum.

It sounds like a train.

It's really haunting.

What we can reliably say is that sleep modulates just about every process in your brain and body.

So assuming that you are sleeping well eighty percent of the nights of your life, or at least working on the various protocols and tools to sleep well and sufficiently long eighty percent of the nights of your life, and you are interested in additional tools that are sound-based in order to improve your ability to concentrate and focus, there are quality peer-reviewed studies supporting the idea that white noise or pink noise have been shown to not improve concentration per se, but to improve people's ability to transition into concentrated states.

There is indeed some data to support the fact that white noise, and to some extent pink noise and brown noise, can amplify the activity of neurons in the so-called prefrontal cortex, this front area, the sort of bumper behind your forehead, uh, that is directly related to your ability to direct your own focus and remain focused on certain things.

These are tools that really have been shown over and over in humans to decrease the transition time into focus.

This is a really key point.

You can do sweeps.

You can do one interesting one, which is called Pink Noise.

I'll show it right here.

I'll set it to the same parameters.

seconds and millimeters um and while I'm doing all of this I just want to mention for me it's a bit easier to talk in metric units we can also change it quickly to Imperial if the audience maybe won't get the feel quickly or convert in their minds what millimeters and inches mean I'll do that right away after I show this but so let's say we generate the pink noise and You might be familiar with white noise.

White noise is basically random points all over the place.

Pink noise, its amplitude is frequency dependent.

So the higher the frequency, you'll have the lower amplitude and vice versa.
