Thank you for this. I've always found myself getting confused with decibels, forgetting which type of log scale (2, 10, or natural), and which part gets divided by 10. Having multiple zero points, depending on the application, doesn't help either!
👍Thank you for the explanation, especially for the 2:1 = 3 dB part, very practical. However, I am a bit confused about the calculation for sound. According Wikipedia, sound pressure level should have a multiplier of 20 instead of 10. At 1:44 , the numbers should be adjusted, for example, 200 mu Pa should equal to 20*log(200/20) = 20 dB, and 2000 mu Pa = 40 dB, 20000 mu Pa = 60 dB. Am I correct?
Never mind. P2, the denominator, would typically be the lower limit of human hearing (the baseline for this equation which could be changed if applied to other concepts).
Now explain decibels Full Scale (dbFS) which are always expressed as negative numbers, but represent values between 0.0 and +1.0. For instance the “Stats For Nerds” display on your video has negative dBFS; it doesn’t represent negative sound pressure which is a non-such. Cheers
I think its easier to learn how to calculate decibels by the formula. Its not that difficult. Everybody who understands how its done with nano, micro, milli, kilo, megaVolts can do it.
3dB is a doubling or half. So if you had 100 Watts and a loss of 3dB the output would be 50 Watts (half the power). If you had 100 Watts and a 3dB gain you would have 200 Watts (double the power).
Best explanation of db ever! Thank you

Excellent explanation. No match for this topic on UA-cam.
Appreciate!
I never had an intuitive understand of dB until now, thank you!
Thank you for your explanation; it was very concise.
Best video on decibels I've ever watched ❤ thanks 🙏
Very clear, thank you
I watched so many videos to try to understand and this one was the best by far!!
thank you, it really help me get the basic of decibels.
Great video, thank you! Liked and subscribed.
Thank you for lucid explanation
Thankyou ♥
Thanks

Are P1 and P2 from that equation differences in pressure in front/behind the eardrum
Never mind. P2, the denominator, would typically be the lower limit of human hearing (the baseline for this equation which could be changed if applied to other concepts).
it's great, thank you sir
thanks
you are so cute i really loved how you explained it
thank you
Are we able to hear 0 dB?

I thought 6 DB is 50%. Is it 3 DB or 6 DB?
3dB is a doubling or half. So if you had 100 Watts and a loss of 3dB the output would be 50 Watts (half the power). If you had 100 Watts and a 3dB gain you would have 200 Watts (double the power).
Good teacher and poor student(me LOL). I still confusing bit.
