I'm experimenting with EQing my iems to meet approach different target curves (within a few dB) and wondered if there's any official data out there that defines them.
Right now I've been estimating the curves from looking at pictures of them: The Olive & Welti 2014 curve (for over-ear headphones) shown here and the 2017 revision of the Harman target for in-ear 'phones shown here. Both sources use 5dB divisions and my estimates are a bit rough. They're probably good enough (especially considering how primitive my measuring setup is and the fact that I'm not aiming to produce a perfect match), but it would be nice to have a precisely-defined target.
