NMC Learning at Home: Spectrograms & Your Voice

For NMC Learning at Home, Evan the Educator uses different tools and technology to show you how the voice works and introduces you to spectrograms, a visual representation of sound.
Look for more lessons that connect science and sound every week, and check out the links below for further exploration:

Awesome!

[@drbobgon]

This video lesson is FANTASTIC! It's just what I need to share with my Voice & Diction course. I only started using the spectrogram representation in Audacity for my voice performance work and have been curious about the information contained therein. This is the clearest, most entertaining and informative explanation/presentation I've seen. Thank you for this! The information is enlightening and the presentation is inspiring!

I love your energy, wish you was my science teacher back when

[@edwardawilson8621]

Excellent video. Information was sequenced in an understandable way with energy, clarity, and humor. Loved it. Now if I could only figure out how to put my head back on...

[@BIackMirror]

Thanks for this great video. I'm trying to learn more about the human voice to make my own little speech recognition system and this video really helped me in understanding the basics. Thanks a lot :)

[@darshandhanajkar5018]

Excellent way of teaching through fun and minor details were covered easily..Loved it

[@CigaretteSmokes]

just amazing, thanks from brazil

[@ivanZart93]

Amazing video.
great examples, very illustrative!

[@brennatoblan8261]

Thanks! I'm adding this to my playlist for Physics 20 Waves and Sound.

[@streammono3218]

dude this video was amazing. really good work u've done here 💜

[@slashtool]

Thank you very much, I liked your understandable explanations.

[@Vilmir]

You deserve way more views.

[@haozhangchu696]

Thanks, I got to learn how to read the spectrogram

[@mmm.mmm.mmm.]

I literally fucking love you. This was perfect for my psych class and you're the most amazing soul. Thanks for sharing your passion for music and science together. That makes it so much more interesting.

You're the best dude

thank youuuu it was great

lol omg he's so cute

[@BohdanTrotsenko]

What's the function of color(intensity)? in rgb or in hsv, or...?

[@abdulgafoor7076]

But how vocal folds produce fundamental vibration and series of harmonics(Overtones) simultaneously at the same time???
Folds vibrate at specific frequency right
Then how Do these many frequencies

[@evantheeducator4075]

Great Question! Nothing really vibrates at "different speeds simultaneously", but most sound waves are messy - large waves have smaller waves between them and our brain organizes these into a series of repeating patterns (i.e. different frequencies)... Let me know if that helps, or makes it more confusing.

[@abdulgafoor7076]

Great information thank you.
Yes sir little confusing.
What I understood is that vocal folds vibrate at one specific frequency(fundamental) and series of higher harmonics are produced by the fundamental vibration.
Large waves have smaller waves between them - confused.
I'm unable to imagine the movement of air particles for large and small waves (2,3,4 waves- with higher frequencies) ?
Even "S" sound (hissing) has harmonics where vocal folds don't vibrate then what is the source for these.
Is there any video of yours sir, like u explained in the above with water example.
I've watched so many of your videos.
Waiting for your reply.. explanation ...

Hi sir. I've little confused of how will air particles look like when they are vibrating under multiple frequencies ??
