AUDIO BASICS (Part 1): How Sound Works

What is a sound wave? How do sound waves work? What does a sound wave look like? How does sound travel through space? In this video, you'll learn the basics of audio science. I've added helpful animations that show how sound works.

Whether you are a beginner to audio engineering or you are seeking a review of audio basics, this video will act as a good introduction to audio science.

Really great explanation. The problem with most other tutorials is they don't show visually the propagation of sound which makes it really difficult to imagine, but you sir have done a terrific job, Thank you!

[frangalante]

I've been looking for this type of videos for a long time. Thank you mate for giving us this information. Apreciate it a lot.
Keep it up!

[BelOo]

This is the best and most intuitive explanation ever. Thank you so much for the time and effort put in this video🙏

[frubo_ssg]

Dear Professor Kyle - nicely expalined.

[amidall]

Just found your channel... This is literally my first comment ever on yt but I had to send some love :DD This is exactly what Ive been looking for really really great job with every video ive seen so far keep it up

[AdrianOlivas_]

Fantastic explanation of the concept! Subscribed!

[a.bloke.alwayslearning.]

Its good to meet someone who understands Newtons Cradle effects.
For years on the News Fusion "Science" App I have been beating it into inculcated minds that is how ALL 'Force' is transferred, by knock on impact and not distance travelled.
They prefer "String Theory".
(Keep a little on you in case you wanna tie something up.
What nonsense !)

My Speciality is Sound.
I am unlikely to ever know every thing, (no one knows what they don't know), but that's chance is becoming increasingly unlikely.

I shall watch your videos very carefully.

PS.
Play that guitar tonight !

I REALLY REALLY needed this. Thank you!

[tbaynes]

Very nice job! Clear and easy to understand explanation. Thank you for sharing!

[sreeshab]

Excellent explanation. It is easy to understand when we think of a Band or a string, as it is elastic medium.

Let's say I take a piece of hard stone and hit it on ground. Even this produces sound. But here stone or ground may not get compressed (being elastic such as band or string). How does then the surrounding air get compressed or rarefacted?

[Christopher._M]

That explains why they say each decibel of sound is more difficult to produce.

I did not find the link to blueprints for diy sound panels. Please share. Thanks for a great video.

[praneethdhanushka]

Dear Sir, if you have any chance please create a video for the concept of Power Compression of loudspeakers.
I think it is also an important part of the speaker's study.

[qwertandrew]

tell us, how and where we can design our room, what absorption need to achieve we looking for ??

[praneethdhanushka]

Dear Sir, how are you? Hope you are doing great!
Please I don't have much clear idea about Power Alley (Subwoofer). I know it is related to Subwoofers and their distance.
If you explain about that I that or if you do a demonstration it will be a nice time.

Thanks
Praneeth

It is actually opposite; a membrane moving outwards will see a low pressure not a high pressure in front of it. That is because pressure is proportional to acceleration not displacement, for harmonic motion. Displacement and acceleration have opposite sign for harmonic motion. Don’t sweat it though, even most acoustic engineers get this wrong. Feel free to reach out if you want to know more about acoustics. René PhD. Acculution.com

Hi, I have a suggestion for a video. Could you research and explain phone recording. Suppose I am recording directly from my phone, what are the issues based on that equipment I am dealing with and the possible solutions. Every phone has a mic and speaker built in and most phones have a headphone jack. Since both these are together in the same equipment what kind of issues can come up for someone who's recording directly into the phone. And what kind of issues can come up if he is recording through a headphone cum Mic. And what kind of issues can come if he's recording through an external microphone (dynamic/condenser) plugged in through various adaptors (without interface/pre amp).
A lot of normal people have begun recording on their phones and want to do so with minimum equipment and simplified solutions. So it would really help them.
Thank you.

That's a nice shirt, what company is it from?

[modmartinez]

Bro why you dripping sweat? Also, thank you for this knowledge.
