Thank you.

Thanks for having me.

Well, I and my medical and audiology students think so.

It's way out of the norm.

I mean, audiologists work with humans, but we are the first group to actually work with audiology of animals.

Yes, absolutely.

Humans can only hear frequencies from 20 hertz to 20 kilohertz.

But dogs, and to an extent cats, can actually hear starting at 30 hertz, but they can hear all the way up to 57 kilohertz.

So they're very on the high end of things.

They have it covered and we can't hear those frequencies.

It's a little bit of both.

Over the millennia, the ear has changed from the most primitive animals.

When the ears change, they change because of some reason that that animal needs to be able to hear those frequencies.

So, for instance, a bat can hear way up into almost 500

you know, kilohertz.

But it's also, when it's looking for food, it's looking for primarily mosquitoes and June bugs, which are very small.

So a low frequency, the bat wouldn't even know that the mosquito was there.

It has to be high frequency so that the wavelength is so small that the bat can hear it.

But when it comes down to dogs and cats, basically,
