I watched a few other videos on this topic, including linustechtips and I was still so confused because those videos bombarded you with all this heavy information that makes it difficult to absorb and understand. But this tutorial broke it down simply, explained it slowly, and presented it perfectly and I now I finally understand the unit of decibels. Thank you for tutorials like this!
This is by FAR, the best concise explanation to the quirks of Decibels I've seen. Here I was wondering if I was retarded, not understanding while watching Techquickie's video. Either Linus doesn't understand it himself, or he's terrible at explaining. This was so perfect I got it almost immediately, thanks a lot.
Hello, thank you for the video. But I have one question I would like to ask. In the pressure-time graph of the Dynamic Range of Sound, how can a pressure be negative? What is the unit used for this graph? thank you in advance.
Sorry, but that is not true The sound pressure level (dB SPL) is defined as: 20 log10 (s1/s0) where s1 is the measured sound pressure level of a given sound, and s0 is a reference value. I showed this in 2min:55sec. This means that doubling identical sound source increases sound by 6dB. 20 log10 (2*p1/p0) = 20 log10 (p1/p0) + 6dB. The 3dB you mentioned will be true if the sound we are measuring is power in that case we would have used 10 log10 (p1/p0) but the sound pressure level is not power. It is an amplitude. The correct formula is then 20 log10 (s1/s0)
Whoa whoa… hold on… you say “sound with 40dB isn’t necessarily louder than sound with 20dB.” But in the next statement you ambiguously reinstate that “sound with 40dB is 10 times louder than 20dB.” Which statement is true now?
Yes I did say "Sound with 40dB is 10 times louder than 20dB." However I never said "sound with 40dB isn’t necessarily louder than sound with 20dB." Watch the video one more time 🙂.
@@TechiTube “necessarily?” Meaning 40dB sound is factually louder than 20dB but not noticeable. So I must say the word you are looking for is “noticeably”.
This is one of those videos that explains things simply and shortly, as promised by the title and thumbnail. Thank you.
Glad you think so!

I'm so glad!
Best video on the topic I've seen yet.
Best explanation ever! You're such an amazing teacher! Thank you a lot ♥️ !
Wow, thank you!

Exactly! i felt the same thing haha It is interesting how a good approach make us learn really fast, and also the oppositive..
This is the only video that helped me understand anything about decibels, but I needed to know about db in relation with radiation, not sound 😭😭😭

Great quick lesson! Thanx!
My pleasure!
So does that equate to 6 dB as a doubling of SPL? I know that in measuring electrical power levels an increase of 3 dB is doubling of power.
For sure the best explanation
Glad it was helpful!
Great explanation. Thank you.
Glad you enjoyed it!
Best explanation ever!
Wow, thanks!
Thank you very much!
You're welcome!
Thanks a lot
Happy to help
Wonderful work thank you.
My pleasure.
Thank you...super video
Welcome 😊
senior at a university, barely learning what it actually is.
Thanks
Thanks brother

Doubling identical sound sources increase sound by 3dB not 6dB
Sorry, but that is not true

I wonder if Dr. Dre knows this
