2. What is Sound?

Sound is a wave, that is, it’s a vibration that travels through a medium, like air and water.

Sound waves cause changes in air pressure as particles bunch together and spread apart. Now, we can’t see these ripples but our ears can hear them. When the waves reach our ears, the air pressure goes up-and-down and this makes our eardrums go in-and-out at the same rate. Our brain analyses these signals and interprets them as sound.

This series is EXACTLY what has been missing for me... other commenters have mentioned the link between music & the physics of sound. I've played instruments since the age of 5 and have been dying for a simple-to-understand, science-based explanation. Finally!! Is there a place to contribute something for your efforts? I'm so grateful.

YOU ARE A SAINT!! I cannot learn something if I do not understand the genesis of its mechanism. I've been on a lookout for lessons in music like these for years and you are the only answer I've found. Thank you soooo much. If you have a link where I can contribute to your channel through donations please link!

HOW MUSIC ACTUALLY WORKS SERIES is the best it solved my frustration on trying to understand how the Piano notes, Chords, Scales are arranged they way they are arranged today. U just don't know im that kinda person that wants to know were things truly begen, in order to grasp it fully. Very much thank you for this hard work of explanation,

[anabiaa]

This explanation is way better than my physics teacher

[alessandrasacerdote]

Tomorrow i have a test about 18 page of sound and you ( saint) reassuned all of this 18 pages!! Thanks!👑

[ArgoBeats]

never disappoint: great stuff. Dig the sfx as well

[emmanuelwynkoop]

It seems to me that the teaching of musical theory should have included some of these scientific topics in order to fully understand the why behind things and not just take them for granted

A sine wave from the center line to the top of the wave, back through the center line and down to the lowest point and back to the center line is called what?

[arcriciaslumingu]

Interesting and simplified way of explaining the topic of sound to students, Physics teachers can take advantage of this video. Excellent video. Thanks.

[emmanuelwynkoop]

Excellent series, absolutely captivating! Thank you

1:24 Correct me if I’m wrong but there is is no difference between sound waves and water waves. This is a difference between surface waves and waves inside the medium.

[TheAbominableChappal]

Wow this video is great, you definitely deserve more views

[budharpey]

geat video, very interesting and nicely animated

If the speed of sound travels at 343 m/s, and frequency is determined by how many waves PER does that mean by the time we hear the sound 1 second and 343 m/s have passed?

[CoolWaveChronicles]

Can you please make a video of "production of sound"...

[ggeasy]

So isn't it heat ? Temperature ? But since it's a wave it doesn't matter because in the first second it heats up and in the next one it heats down..maybe even a millisecond. So it's just oscillating temperature, right ?

Bulk water acts lon-digit-unal. Strong sea or ocean botzom currents.

Likewise sound in CLO-SED spaces...aka META-mat-eria-L is TRANSVERSE. The more syMMetry is broken, coupling is easier.

[gabrielaguiribitey]

What is the larger the number of cycles per second of a sine wave?

[federicopaez]

Who was put here from school during quarantine

[bluename]

how would you explain and visualize "analog" & "digital" sound?
