Oh, hi, hi. So it's still that Bobby Penn under the couch cushion. It's Ali Ward. We're back with part two of Laren Gollogy.

So if you are tuning in without part one, I don't know what to tell you. Go to part one. And then we'll see you in like an hour for this follow up featuring wall-to-wall questions from folks supporting the show at patreon.com

Sociologies also thank you to everyone who rates the show and leaves reviews. I do read them all. Here's a little fresh proof. Thank you Kate Ted mobbed who left the review been listening since 2019 and it's still my favorite podcast. You've been with me through college pandemic and now through every relocation and long distance flight.

I'm honored to be jammed in your ears. Thank you Kate Ted mom for that. Okay, let's move on part two. Thank you to everyone also who let me know well some docs may say like to the HPV vaccine after the age of 26. You can still request it and probably get it covered by insurance much later in life than that if you want.

So talk to your doctor. You totally have my blessing. Also those beats were made by Jason Skardamalia. Thank you for making those. That was amazing. Okay, so get yourself a couple warm tap water and let's hear your questions as I say them with my mouth. We'll cover whistle tones, Mariah damaged your voice box. The lowest voices, throat singing, perfect pitch, stress and voice cracks and more with surgeon.

M.D. icon and your new favorite Larianologist Dr. Ronda Alexander.

Okay, let's start your questions with GG and first time question ask her Chris Lippford's inquiries about increases words. What the heck is going on when people sing in the whistle register?

I need to know everything. Please and thanks. Okay, I have these on my phone. So many Eric K wants to know is it possible to make a sound outside of the human hearing range? Would we know? I don't know. I don't know. Do we need like a bat detector? So we we could detect that with specialized audio equipment. I don't think we've ever tried. I don't know. I'll look it up. Maybe ultrasonic. Who knows? Okay, so I checked into this and according to one BBC report.

We can hear frequencies up to 20 kilohertz, but most human beings cannot shriek higher than three kilohertz unless your Mariah Carey singing her 1991 ear splitting single emotions.

So good. So that was from the 1991 VMAs, which experts say was her highest recorded note at a G sharp seven, I think, which would be 3.3 kilohertz.

So is that like dolphin range? Almost. I checked it in those marine mammal friends of ours can whistle at 3.5 to 10 kilohertz. And actually in looking that range up, I stumbled across an absolute Venn diagram of this aside, which was a 2021 tick-tock of Mariah in the ocean singing a whistle tone to a dolphin who seems to react with some kind of surprise.

Maybe glee, I shouldn't anthropomorphize, but speaking dolphin, Mariah and setting world records, but then along came Georgia Brown, which is a stage name for an Italian Brazilian singer who was able to best Mariah and hit a G 10 note.

So I'm going to play it. If you have really sensitive ears, just turn down your volume for a second or skip ahead 15 seconds because it is bonkers.

So that would be around a 5.5 kilohertz like mid dolphin range. So if you're carpooling with dolphins, they loved it. But those are the highest of highs. There's got to be a low. There is. And its name is Tim. Tim storms, an American country crooner can sing eight octaves below the lowest.

Piano key making a sound that is less than a single hurts point one eight nine hurts to be exact. So we can't even hear it, but we can feel the vibrations. And of course, I don't have a recording of that because again, we can't hear it. But here's an example of Tim's just casual every day non record breaking singing.

One of the top comments on that YouTube video is thanks this dislodged my kidney stones. Now, of course, our hearing can change over time. But what happens to our voices over the whole course of our lives.

So many of you had this question, including Virginia Bruce, Hannah Lafam, Lannish Euster, Celia Bell, Andrea Crane, Meredith Snowlander, first time question askers, Laura Roser and Coco Wenzoso.

And Courtney Kay wanted to know are there strategies to prevent our voices from aging. So to reduce the impact of aging on the voice, stay hydrated, take a good care of your voice.

Again, those three rules, no cell phone outdoors, no yelling, no whispering. And if your voice is in trouble for more than about 10 days to two weeks, come see somebody who can talk to you about options.

I really love this question. Delaney, Jen A Greg, Wallick, Bennett Gerber, Jade Walker, wanted to know in James words, voice breaks, what are they? And Bennett asked, why does my voice still crack? And then also Jen A and Delaney wanted to know, why does being nervous make our voices shake?

Like when you watch a TED talk, and you can tell someone's nervous, a little warbly, what's happening when our voice cracks?

Okay, so there's two different kinds of cracks that I'm hearing in these questions. One is the crack that happens when you have into made the switch from your chest voice to your head voice or the falsetto.
