You partly answered your question because sound intensity is the key.

And as humans, we can produce only sounds of certain frequencies.

And throughout history, people have used horns.

Horns really work.

And so that would be the first thing that you do.

And you can even create it like this yourself.

Exactly, to project.

But if you have a longer horn, use that.

That really works.

In terms of our human ability to detect tones, in every species, it's a sensitivity curve.

So, when we test hearing in clinic, we tested only up to 8 kilohertz, but we can hear up to 20,000 hertz.

And it's because most of speech really lives below that frequency.

Lots of speech lives between 250 hertz and 4,000 hertz.

And if you speak at those levels, which we do because that's what we do as humans, women can have more high-pitched voices or children can have more high-pitched voices, but it's still in the range of optimal human hearing.

That's what you would need to do.

So then all you have to do when you're in a situation like that is speak as loudly as you can, and if you can, find a horn so that it amplifies.

Intuitively, exactly.

And that works too.

It absolutely works.

Our patients tell us it works.
