No explanation of how the files were made found in the dangling thread.
Just static EQ will not do it, in the not improbable case it was used.
>>> Interesting. Does anyone know of similar sounds for speech?
>>> I've got high frequency loss
Undefined variable, everybody has some kind of high frequency hearing
loss, if not then their hearing extends to 32 kHz.

Masking theory is needed to explain why it doesn't.

It is somewhat non-simple because the recruitment needs to be modeled

In terms of comprehension it equals the hearing loss. It was btw,
beatifully modelled with Homer Simpson as example in some episode of the
Simpsons. It should be easy to find it, it is one of the 3867 with a
real rockband in it.

The above considerations will have to be accounted for in the sound
design, at a glance it should be doable, but not simple.
