- In this brand new module, we'll try to answer the question of how loud a sound is. As we dive through this module, we'll quickly find out that answering this question is not as easy or intuitive as it seems. But before delving into the concept of measure of levels and the human perception of loudness, we'll take a look at the obscure and often and often overloaded terminology used in acoustics to represent the general concept of how loud a sound is. Loudness, volume, level, amplitude, gain and drive.

In this module on Loudness and Level we'll delve into how our sense of loudness is different for different frequencies and all the nuances associated with hearing. We'll look at level, and the technical ways of measuring and calculating the amplitude of signals. And finally we’ll look at a new way of measuring loudness that’s all the rage at the moment, the Loudness unit. It has redefined the standard used in streaming and broadcast, and promises to bring an end to the age of super compressed audio and the so-called loudness war.

Corrections:
4:33 The gain isn't positive or negative. The gain value would range from 0 to 1 when the output is lower than the input and beyond 1 when the output is larger than the input.
Probably the only video on the internet that explains these basic concepts so well. Thanks a lot Akash for sharing this knowledge.
Thanks a lot Oscar!
Next-level UA-cam sound design content. Sharing knowledge is a holy thing, especially this well. Marvellous, thank you.
Glad you enjoyed it! It takes a while to make these videos, but I'll be putting more stuff up over time for sure..
This this the best channel on these topics I've found so far !
Thanks for that! :)
Gentle reminder ！Seems that there is a spelling error (Amlitude) in the video in around 9mins period ！ Minor error ，no big deal ！ 😊
I love to watch your video ！Very Clear explanation ！ Thank-you ！ 😊 👍
Good spot! Someone else spotted it earlier as well. Unfortunately, there's no way to correct it now!
For the first time in 20 years, got someone who made sound basics much clear.
Great to hear!
Your tutorials are very well done, thank you
Wow! Amazing. Ellegant and super professional. The best video ever on the subject. You're the man.
Thank you very much my man!
Love your series on Audio Theory. Learning so much, and finally starting to have a clear global vision about the subject.
Thank you !!! :)
You're welcome! I'm glad you find these useful!
This is kickass, thanks for sharing your knowledge!
Thnx for this tutorial.
You have clear my confusion i had from the last 10 years 😊✌️🙏
Glad it helped!
This will be on my further reading recommendations list for all my students! Excellent!
Fantastic, thank you!
Mind Blowing....Elegant.....Amazing
Cheers!
on loudness section, 3:17, slide says "pyschological" instead of psychological. and on amplitude/level section slide shows "amlitude". amazing work man!
Oh jeez! This was one of those videos that I forgot to do a spell check! 😂 Thanks you pointing that out, eagle eyed viewer!
@@akashmurthy no problem! i know! haha it happens really often. it has happened to me too with slides or papers that i have even triple checked myself. then a friend comes and reads the thing and in a matter of seconds spot the typos. just the way it goes!
These are awesome videos, Akash! Much talent you have!
Thank you Kate, that's very kind of you!
Great video, as always! Thanks!
Thank you!
great lesson
Cheers!
Much respect to you for this in depth lesson, you're awesome!! Goatt
Thank you kindly! :)
excellent
Great video Akash, these concepts are especially tricky to learn when you have no exposure to audio engineering! Whilst I learned what these things were through producing more than studying a video like this, I still find this very useful as I would've previously struggled to describe the concepts if someone had asked
Thank you very much! I find the terms hard to describe as well sometime though I might know it intuitively!
All my questions have been answered! Now I am an educated guitar player. Thank you.
Thank you! Glad you found it helpful!
Very well done. I'm surprised you don't have more subs.
Thanks. You and me both!
Excelent video! I am subscribed and i going to watch all videos!
Awesome, thank you!
I have said this before though you are amazing 🙂
Awesome content and delivery, thanks a lot! How one can start creating such high quality presentations and videos with animations? Could you share what tools you used?
Cheers mate!
I use After Effects for all the animations, and I learnt a bit of motion graphics on Udemy. That's all really!
Love, love, love your videos. FYI amplitude is spelt incorrectly at 6:06 (amlitude).
Thanks so much mate!
And that's an embarrassing mistake, this was the time before I started using spell check scripts! :D
Hi Akash, I have a question from your last framed sentence??? How come turning the volume(output) knob down will reduce the gain(input)of the amplifier???
By the way, I would like to appreciate your efforts in posting such amazing content! Expecting much more useful content shortly. Thank you 😀
Hey man, "gain" doesn't have to be input gain right. There could be several gain stages to an amplifier. And it was more of an example to indicate that gain is property of an amplifier.
👍
4:36 if gain = output / input, then it's either greater than one or less than one. It's always positive. If you take the log of the gain, then as you say, positive values less than one become negative, and greater than one positive. Is that what you did, or is this a mistake?
Excellent playlists, learning a lot, thank you
Hey mate, I think I might've messed that one up! You're right, amplifier gain is generally positive and values would range from 0 to 1 when the output is lower than the input and beyond 1 when the output is larger than the input.
Negative gain in possible in inverting op-amps, but that was definitely not what I was going for!
Thanks for the heads up.
Helo, my name is Wilma and now i have to writting my final project about noise. your content is all i need. may you don't mind to tell me the references? thank you in advance
Hello, please check out the description of the other videos in this series (Loudness and Levels) and you can find a few references that you can use.
You say a few times that volume can't be objectively measured; but what about the dB scale?
You use "level" or "gain" right? We don't use "volume" in the context of the decibel scale. Example: Boost the gain by 3db. The guitar levels are at -10dbFS.
thank you,very clear explained .I sent you DM on Instagram
