Hello, Brainstuff! I’m Cristen, and today we’re going to talk about the human voice.
First off, let’s acknowledge that everyone is a special and unique butterknife, and there’s no rule about how men and women’s voices should sound. But on average, adult men’s voices have what’s known as a lower “fundamental frequency” than adult women’s voices.
The fundamental frequency is simply the scientific term for how high or low a person’s natural speaking voice is. Sound frequency is measured in hertz, which means how many times something happens in one second.
So a sound wave that vibrates 100 times per second produces a tone of 100 hertz. The more cycles per second, the higher the pitch.
Babies usually cry at a frequency of around 500 hertz. Children have speaking frequencies in the range of 250 to 400 hertz.
By the time of adulthood, however, men have an average fundamental frequency of about 125 hertz, and women about 200 hertz. What happened here? Why the big difference?
To understand why men’s voices end up lower than women’s voices, we need to look at how the body produces sound. So let’s take a magical journey to the inside of your neck!
Leading from your lungs to the cavity behind your mouth and nose is a pipeline called the trachea. You use it to breathe. At the top of the trachea is a hollow organ called the larynx, or in common parlance, “the voice box.”
The larynx is also what allows us to make sound for talking or singing. To do this, you use your lungs to push a column of air through the larynx while using your laryngeal muscles to press together a pair of membranes called the vocal folds, or more commonly, your vocal cords.
When you close the vocal folds like this, the air you push out through them makes them vibrate, and this vibration leads to sound.
There are several factors that can all have some effect on the fundamental frequency of a person’s voice, like the size of the larynx and differential development of facial bones and cavities in the head, but the most important factor to talk about is the length of the vocal folds.
If you pluck a string, the length of the string affects the frequency of the note that plays.
Think about a guitar. When you press a string down to a higher fret on a guitar, you shorten the length of the part of the string that vibrates when you pluck it, and this produces a higher note.
The same thing happens inside your larynx! The longer the vocal fold, the lower the note.
During puberty, both boys and girls experience growth of the vocal folds, leading to lower voices. But the male hormone testosterone, which is released by the testicles during puberty, typically causes boys’ vocal folds to grow longer and thicker than girls’.
On average, adult women have vocal folds somewhere around 10 millimeters long, while adult men have focal folds in the neighborhood of 16 millimeters.
Consequently, women are up there on the upper frets soloing into oblivion like a high school kid who just learned to play “Eruption” by Van Halen, and men are letting the open strings ring like the intro to “Nothing Else Matters” by Metallica. Y’know? Y’know?
Bonus! Everyone knows what happens when you inhale some helium from a party balloon or, you know, straight from an industrial helium transport truck - your voice pitch gets higher. This is because helium is less dense than air.
But did you know you can reverse the effect and give yourself a deep, booming bridge-troll-voice by breathing a gas with a higher density than air, like xenon or sulfur hexafluoride? But remember, your body needs air to live, and breathing anything other than air can potentially be dangerous, so we don’t recommend trying this at home.

The voices of boys in cartoons is often played by adult female voice actresses. I have a friend who is a professional voice actress, and she has done the voices for many boys for cartoons (in addition to the voices for many female characters).
Okay ?

Correct. Sound frequency is measured in hurts. The more I hit my victims, the louder they scream.

1:40 makes me uncomfortable. A lefty with a right-handed guitar?
+BoeserKlon Cristen's a lefty, but the guitar happens to belong to Paul, our (right-handed) producer.
I'm a lefty, but play guitar with my right hand.
+BoeserKlon Makes sense. She looks like the genetic archetype called the Explorer. Probably sensitive to caffeine and has the rare *radial loop* on one of her index fingers. I am a wizard.
+Eric Morrison Well, I would never contradict a wizard.
The strings are backwards for a lefty player though. That's why it looks so strikingly wrong.
I actually need to heighten my voice. It sounds lower than my grades
Same I don't like it. I feel like cutting it and then slicing it so thin I'd have the highest voice.
shaka mata _ African pride well different people different opinions, so if you like having a deep voice, then sure. Enjoy life, man.
I have deep voice, and I'm not comfortable when talking through phone, and video call. It's very weird to hear my voice
Bruh how high is your voice
Trust me man. Girls love a deep voice. My girlfriend said she loves it. Don't worry.
Also before I hit puberty, I had the most high pitched voice ever. And I can confirm its better to have a deep voice
My voice dropped through the floor during puberty. I went back to school after the summer holidays and when I spoke everybody just stared at me. I listen to bass singers that seem to struggle with the lower notes, that is somewhere in the middle of my range. I have 3 sons now and we all sound similar, when we speak together my wife says it's just a deep rumbling that she hears.
Same with me. I came back after summer and I hadn’t hit my growth hormone yet clearly, but my voice was incredibly deep. My classmates told me it was the most fucked up thing seeing a 5’2 13 year with the biggest baby face talk like something straight from the underworld.
0:14 I love how she clarifies that, because from 2015 on everyone seems to be getting offended by everything.
and now it's 2022, people complaining abt liking the same gender
This is more of a "how" do women and men have different voices... I'm looking for evolutionarily "why" do women and men have different voices.
The evolutiom is bullshit
It might be that Men as hunters needed to be able to roar to startle an enemy or scare off other predators, it could also be used as a way to establish dominance by how deep one's voice could get, while women's voices was most likely not as deep to help alert the male of a dangerous presence with a different scream, and tell them that sth is wrong, and perhaps for sexual reasons too?
Did anyone notice that she held the guitar on the opposite side as normal...?
either it was a left handed guitar or the video is mirrored
+Rozamunduszek the guitar looks normal. Probably she doesn't know much about guitar and there wasn't anyone knowledgeable around to guide her.
+GoldViolinFlutist didn't really rewind the video to see the guitar. I just assumed she didn't held it upside down. And if she hadn't that means that the guitar must have been left-handed or the footage been mirrorred. But maybe I did overestimate her and she holds the guitar upside down.
+GoldViolinFlutist Cristen's a lefty, and the guitar belongs to our (right-handed) producer, Paul.
+BrainStuff - HowStuffWorks I see. I was thinking all the other instruments (percussion, keyboard, brasswind, woodwind, orchestrial string family) are all played in a standardised direction regardless of the player's left/right handness, and doesn't matter how symetrical or asymetrical the instrument is. So I assumed guitar would be the same.
Very interesting. This was a more in depth explanation than I ever received in health class during my school days.
As a side note it is sad that these days we need to have a disclaimer at the beginning for those that will inevitably be offended.
+Christopher Lantesh We weren't being PC, we were being scientifically accurate.
oh god my voice is deeper then hers and I'm only 12...
every 12/13/14 year old should have a deeper voice than her. Voice matures faster than body.
Oh

+Suvi-Tuuli Allan that's objectification. I'm a meninist now.
lol k
my response is "it's physics"
It's OK to be male.
Still stuck with the question "Why do men have deeper voices?" - this video didn't answer it. Video should be renamed to "How men have deeper voices" or "What causes men to have deeper voices."
Because of the lenght of the men's vocal folds with 16 mm
Men have more than 10 vocal cords whereas women can have maximum 10 vocal cords and that’s when is a woman considered to be a deep voiced :/
are you asking about the evolutionary reason? it likely evolved in early humans to establish dominance between males in a heirarchy. to compete with each other male voices became deeper and deeper until they reached the pitch they are today
Um, actually, my good lady, and script writer(s), the vocal folds act not like a guitar string, but like the neck of a balloon. Frequency is increased through stretching, not shortening. Not sure why men's voices are deeper: if they truly are longer. Maybe the female vocal folds are tighter/stressed, while the men's are looser/relaxed.
Do I get cake now?
We don't recommend trying this at home
Me: Okay, I'll try it on the park or somewhere that is not my home.
...ok, so does that mean women with deeper voice can take it really deep?
go fuck yourself

0:10 - 0:19 thanks for clarifying, I almost got triggered for a sec there.
I hit puberty when i was 11 in 5th grade and now I'm going to 8th grade and I'm 13 and my voice has been deep for a while now
My voice tested as this.
Average: 93hz
Minimum: 65hz
Maximum: 207hz
Minimum average: 85hz
Maximum Average: 102hz
Helium doesn't really work for me, it's odd.
I think my hormones messed up because I’m taller than both my parents (5’10) and I’m 14 and my voice is lower than everyone at my school, and this age is when every boys voice is low af so knowing my voice is lower than everyone’s is sad.
On December 1st, I got sick and my voice got low.
1:40
You're holding the guitar upside down lol
For all those who did not get the answer they are looking for I will tell you.
A deep voice signifies high testosterone, which tells the listener the speaker has a big body.
Useful for scaring intruders from the territory.
I can’t make my voice any lower😭 even when I try💀
this was actually quite interesting, as i have a very low voice for a female.
Thank you this was vary helpful
Talking about voices vs musical instruments may remind me about something when it comes to singing voices. I was a deep speaking voice and now I have a light but med range male speaking voice but in singing voice I'm a tenor who started singing as a baritone. If the singing voice is high both in women and in men they would be set to be sopranos and tenors if deeper altos and basses but that's a complex case for mezzos and baritones.
The nice thing about breathing helium is that it floats up and out of your lungs, almost by itself. But you need to bend over and pour out sulfur hexafluoride. Or it just lays in there and suffocates you.
That is a terrifying visual
When i was little i thought a beard gave you a deep voice.
Ok and
oh i miss my old voice i hit all by myself but now my voice become deeper huhu how can i back my original voice
I feel like there are people who just dislike a video just to dislike it
wow i love this video thank you so much
Short answer: TESTOSTERONE
How would I find out frequency of my voice?
Is Adam apple stop the height in puberty stage
Im a man but i have a lower and girly voice i know plus my classmates say that sometimes i cant do deeper unless if i tell my brain to do it
I’ve been told I sound like a woman on the phone and I’m a Dude and Im capable of singing like a guy and girl but what’s even stranger is that even thou people think I’m a girl on the phone I’m not even trying to use my high girl voice I just have a very soft feminine like voice sometimes
Actually helium doesn't affect the pitch of the voice, it affects the medium in which the sound waves bouce around in the vocal tract, producing a different "eq" of the same frequency!
I've tested this myself singing "row row row your boat" without and with helium. Same notes, different "resonance" or "eq".
I am 24 and I have a high pitch voice... my voice frequency is around 210 to 215 Hz... please suggest on how attain low pitch voice....
that is nothing. im 12 and my voice is around 300 Hz.
when i speak on a girl they got scared on how deep my voice is so that's why sometimes i heighten up my pitch for them not to be scared or something. i only show my deep voice through singing
Cap. Tryna sound cool on the internet.
I just played the Eruption guitar solo and the Metallica official music video together.
It just works.
Great video but you could have demonstrated the Gas thing!
is there a way to regain morning voice?
Yes , Thank You teacher for the tutorial on how Men & Women voices are different! The next chapter should be why Mother Nature made this so?! 🌷🌿🌎
Clearly she sat on a speaker with the bass full blast. “ you know”
I am 14 and have 100hz. It's not broken.. i don't think?
Why is there background music? It is so annoying. People are quite capable of expressing themselves with words. They don't need background music to set the tone.
But...Whats the natural reason? I've thought about that alot. Like I mean, why are our bodies "chosen" to produce low freqs in men and high freqs in women?
1:44 tell me what you hear
I just woke up today and now I have a really deep voice. Yesterday it changed also and got deeper. I’m only 11 but I have a deeper voice than her
My voice is deep I’m 23 and I sound 50 women love it 👊🏾💪🏾
I sweta god im a boy and my voice sound is so squeaky i sound 5😭
How old are you?
I tried a voice tester and it said 85-100 hz is it good?
My voice been deep since 5th grade and now I'm in 7th going to 8th grade
I’m 15 and I still have a high voice which I don’t have problem with actually!
cristen & Josh are the best
lmaoooo why this music sounds like your trying to set the mood... Whats the name of it though it's real good
But what about trans women. Why do they get higher voices if its just the size of the vocal folds? Does having female hormones reduces the size of the vocal folds?
I just read the same article they used to make the script
Much respect for the metal references 😂
I think you would be kind of cool if there was a tad bit on getting sick and how that affects your vocal chords. I mean come on what's going on there
What makes a person right- or left-handed or ambidextrous?
The Devil.
except me ...I hate it as I don't have deep voice like some men (who have very deep voice )
i sounded like a fucking chipmunk at 18 now my voice is deeper than the Mariana trench.
Best musical references possible!
awsome video
How can I achieve this
Is this why women can talk faster to complain about other women, talk nonsense all day, etc...?
Yes
fd11fd33fd99 yes. it's also why they sound more high pitched and annoying when they complain
Rickish Monkey66 Misogynist shit
I like your pfp
I have a question guys can a boy take a medicine or surgery to make their voice like a woman
My voice is not close too deep and im 25.
I noticed almost every one hate when I talk with bass in my voice. I tell them don’t give a damn because I’m not gonna change how I talk. My personal experience, sometimes I get a kick out of it
my brother is 12 years old but why his voice like a adult man?
Nice guitar by the way.
How do i have such a deep voice than.
I'm 10 and today I was talking suddenly my voice got weird and deep is this puberty?
Yes
bruh your voice doesnt change in one day. it takes months lmao. my voice still has not dropped and im 12
Why do female voice have more resonance than male one?
It must really suck being that guy whose voice is higher pitched than that of the average woman.
yes it does.
I’m 15 And My Voice Is A Little Deep And I’m A Girl Lmao😂😂😂😂
Same but i’m 17 😂
Why is test anxiety a thing?
My voice matches my appearance. Im a tall burly teenager with a voice that sounds similar too Luke Stoltman's voice but with a black southern accent
Watchig with my voice 4 weeks on T
This is all fine, but do we really need the disclaimer at the beginning? Have we become so over-reachingly sensitive that we cannot simply present science in a scientific way without apologizing to somebody for it?
In the next episode of 'How stuff works' we will learn about guitars; which way up to hold them and how to properly wear the strap so you don't look like a complete noob.
Perhaps you should make your voice deeper Christine
I have to *_scream_* to clear my voice.
It's that deep.
Men don’t have deeper voices anymore!
Lots of female feminist voices are very deep!!
I wonder what it sounds like when they hit puberty twice🤔
We call them *Corpse*
Why was the guitar upside down

Hi, Cristen.
I already have a deep voice. So it’s nice to make it better
I have a Lower Herts because I didn't get enough Sleep.
