And cortisol is a hormone associated with stress.

And what we found was that regardless of the type of music you're listening to, be it creepy or relaxing, cortisol levels went up.

On top of that, across both conditions, so across both types of music, people rated the music as sadder.

And they found it less interesting as well.

They reported just generally feeling more irritated in the presence of infrasound.

Exactly.

And I think it could at least partially explain some hauntings in that sense.

So as you said, if you walk into an old building and you don't know what infrasound is, which most people don't, you're feeling something.

Especially if you're going to the basement, there's a really good chance that there's some little rumbling pipes down there or an old boiler.

Yeah.

And if the setting is right, so it's dark, it's creepy, you feel something, it's quite reasonable for someone to believe that they've experienced a haunting when in fact what they have experienced is an old boiler.

That's actually our follow-up study.

So we are looking at that now.

We are going to different supposedly haunted locations here in Alberta.

And we have control buildings that are not supposedly haunted.

And we're looking to see if the infrasound levels are higher in these supposedly haunted places than places that aren't.

So we just got started on that.

We've only gone to about four, I think maybe five locations now.

So it's on its way.

We're looking to see if there are any differences there.
