The blue line is a fletcher Munson curve/equal loudness curve. It's an average measurment of human range of hearing for each frequency.

The curve isn't ideal for headphones or audio as a target, and also changes by listening volume and flattens quite a lot as the volume increases.

The only other person I've seen use the equal loudness curve as a target is nouvraught, although he would do it by first compensating the headphones FR to diffuse field first, and then comparing against the equal loudness curve... not that it's to be taken seriously anyway. As far as I know, it's mostly baseless methodology

The problem with the Fletcher Munson curve is twofold.

Sound engineers mix on neutral monitors, which have a very flat response. because of this they compensate for human sensitivity in the 5k region by dropping it down naturally.

The second problem is that by definition the Fletcher Munson curve changes with volume. So equing to it only works at 1 specific volume. The real way to compensate for it is with loudness controls, which boost the bass and treble at low volume.

Probably not. That's a huge sub-bass boost that would probably get exhausting for me quickly.

Maybe for movies, for the rumbling effect.

If the curve would start at around 80Hz then yes. This would be ideal for the common people that only knows Dr.Dre or raycons.

LOL, that is exactly what I had in mind, the original Beats with their 10 dB bass boost around 100 Hz.

Definitely not ideal, at least for me. Why does it show such a huge subbass boost?

That much energy at 10hz? 20? Increasing exponentially as it reaches lower?

That bass wouldn't even be perceived as sound, these frequencies are perceived as a pressure on the ear canals, such aggressive response that gets more and more pressure the lower it goes would be waaay too uncomfortable.

This response is hardly any sound, its simply a pressure build up.

The headphones I liked the most all have some kind of roll off. Heapdhones can be bassy and fun and still have a down slope on sub bass, I find the best bass tohve a boost up in the upper bass instead of more sub bass than upper bass.

is that a 45 db bass boost lol???.

No that is by no means ideal.... thats an equal loudness curve and its not a headphone target.... its got nothing to do with one....

Who doesn't love a +40db boost at 5hz
