YES I FINALLY UNDERSTAND HOW TO READ THIS GRAPH. i failed my psychoacoustics exam 3 times because i wasn't able to read this goddamn graph, now i understand it, thanks
Small correction: If you add two 90 dB values you will get 180dB not 93dB. Decibels add in the normal fashion. If however you are talking about power increases or decreases, such as going from say 10 to 20 watts or reverse, this will give you a 3dB increase or decrease depending on whether you are going up or down in power.
NO, if you add two equal dB-values, you get an increase of 3 dB. Imagine having a violin that produces 60 dB then two violins do not make 120 dB and four violins don't make 240 dB.
@@ronvonk6144 - Interesting, I fully get your point and analogy, admittedly I never looked it that way. I think you are still talking about two sources of identical power or intensity so there is acoustically a doubling effect which equates to only 3 dB increase in SPL. That's what I get for being immersed mostly in the electronics point of view where I have always added or subtracted the dBs depending on whether I had gain or a loss of X amount of dB. Thanks for the clarification.
Very nice! thank you, it is actually hard to read these curves if you're not aware is about the decibels needed to perceive a linear response. Instead of just a graph of the response.
the frequency responce does NOT flatten out at louder levels at 2-4KHZ, at these frequencies your ear becomes more sensetive at these leve;ls. that explains why when I listen to music at 90-100DBC I have to trim the 1KHZ to 6KHZ. at 2-4KHZ the threshold of pain is "only" 105dbc!. on my 15" PA speakers if I run the system flat 100DBA is insanely loud and 105DBA will utterly destroy your hearing. I normally listen with bass boosted and 1KHZ-6KHZ cut4-8DB and running 85-90DBA and 95-100DBC.
I dont do live sound at all, I run these in my living room, Ive been building speakers for 30 years off and on. , I prefer pro sound equiptment to home speakers although I own both.
You could, what you would do is just start them at the same volume level, so make sure the levels on both faders match, then adjust one to match the other. You could just use a frequency generator for the source sound. The difference will tell you the perception difference you needed.

Nice explanation-had been struggling to understand what the curved lines actually represent. Now I know!
4:00 that's an exponential curve btw, logaritmic curves have the opposite tension
Gosh dangit, I get them mixed up all the time.
Unless you will do a math series it's not a big deal ;)

Situation, like: "Well, it's up to you to check the 15 kHz at 120 dB". ->Cry.
at 15KHZ? what about 120DB at 2KHZ to 4KHZ!!??!!, at these frequencies 120DB is 15DB above the threashold of pain! that guy is certainly deaf now LOL!

#datruth! Sounds like you do a lot of live sound.

How could I test this out on my DAW?
I'm not sure I understand your question. Test in what way?
Is there a possibility that I download 200Hz and 1000Hz sine wave and adjust the dB level of 200Hz to sound as 1000Hz.
You could, what you would do is just start them at the same volume level, so make sure the levels on both faders match, then adjust one to match the other. You could just use a frequency generator for the source sound. The difference will tell you the perception difference you needed.
Composing Gloves where is the frequency generator on logic?
Its been ages since I've used logic so I don't remember if they have a dedicated one, but you could always just use a sine wave output on any synth
