Filter Curve EQ vs Pass Gain Filter

Attached image of the Filter Curve EQ I want to use at -6dB and -12dB. I also use similar curves at -24dB and -48dB.

For my application I’m reducing the dB of frequencies below and above the boundaries of intelligible human speech 120Hz and 9000Hz. As those frequencies outside of the range of intelligible human speech are raised louder and louder the muscles of the inner ear are more and more engaged. This application ostensibly will be used for the improvement of audio engagement for autism.

Would these particular Filter Curve EQs be more effective than a combination of High and Low Pass Gain Filters at similar dB levels?

I’m more interested on the effect of audio on the human brain and inner ear muscle activation rather than subjective sound quality.
