frequency response headphone

I know it's stupid that I don't know. why here they show from 70 to 120 dB, to be honest, I'm used to the values of DAW, for example, there is from -70 to 6 dB.

Decibels is a relative unit. So the question is: what is zero dB? How come there are differences?

The "zero" point is usually chosen for ease of calibration specific to what is being measured.

In acoustic measurements, 0dB is total silence (for the average human, some people can hear sounds at -3dB and others cannot hear sounds at +3dB)

In electric measurements, 0dB is a voltage with an average voltage of (I think it is) 0.7 V. (this is a bit more complicated actually, there's dBV and dBu)

In the DAW / VST world, 0dB is the maximum level you can get without the audio interface going clipping: full scale. There always is such a point, regardless of bit depth.

Because of these differences it's good practice to put a suffix: dB(A) for acoustic, dBV(rms) for volts root mean square, dBu for "unity", dBfs for full scale.

Double post.

hmm, did I block the second one or not. my fault i'll take a look now

Not stupid at all. This can be quite confusing. Short answer is that these values measure different things. I would not worry about that too much. What you can do is simply do a slow sweep in your DAW and check the perceived volume for each frequency after EQ. Ideally, you should hear every frequency at the same level.

I got it like this. Big difference

Today my brain is exploding, it helped a lot. Thank you so much )

That’s a pretty harsh mid bump. I’m dealing with mixing for the Meta Oculus 2 and it’s got a lot of low end roll off and a big spike around 3.5 kHz. Some EQ helps, but the truth is, sucky headphones are sucky headphones. The good news is, replacements from AKG, Sennheiser, and Beyerdynamic are pretty cheap these days.

As long as I have these headphones. Could you please advise me how to correct this temporarily.

I am not an expert but this is where I would start.

Try bringing the level around 200 Hz down a bit and the level around 4-5k Hz up somewhat. Choose a fairly wide q for the 200 Hz adjustment and an as wide as possible q for the 4-5k adjustment (you do not want to increase the bump around 8k). Try to stay within 1-3dB for these adjustments.

I did a similar thing not that long ago when I decided to adjust left and right channels in my setup to match my minor hearing loss in my left ear (which looks a lot like your frequency graph). Two small adjustments at 2.5dB each did the trick for me.

But once again, I'm not an expert, so take this with a grain of salt.

Very clear and detailed explanation. I hope to do it right)) this morning I have been reading for several hours trying to understand what it is, because I did not know about it until today. Thank you so much. helped a lot.

Another option is to play a track that you know very well and make adjustments until you think it sounds right. Keep in mind the response curve, but also don’t forget to trust your ears.
