The terms "auditory" and "auditive" are different concepts. ISA expressly uses the term "auditory".
I am already 40 years used routinely Bark scale and the auritory filter bank model since my Otaniemi year 1983. I developed our own auditory filter bank model together with professor Matti Karjalainen.
Over the years, I have coded as a DSP man auditory filter bank model completely from zero
(1) for "PDP-11/34 Floating Point Systems FPS 100 Vector Processor" in Fortran,
(2) for the Texas 16-bit TMS320 signal processor family in machine language,
(3) for Motorola's 16 and 32-bit M68000 microprocessor families in machine language and C language,
(4) for IBM 600 Series 32-bit PowerPC Microprocessor Family in machine language and C language,
(5) for Intel 32-bit and 64-bit microprocessor families in C++ language.
Analysis pictures I have coded from the very beginning in Neon object-oriented programming language.
Hz is converted to Bark by the formula x/Bark=7ln[f/650+√(1+(f/650)2)] and Barks are converted to Hz by the formula f/Hz=650sinh(x/7).
I have used the above Bark conversion formulas since 1983.

1000 Hz sinusoidal signal spectrum in dB/Bark/Hz scale.
Toivonen's and Karjalainen's first auditory spectral series on diphthongs in the Otaniemi Acoustics Laboratory in Academy of Finland project Puheen kuulemisen mallintaminen (Auditory modelling of speech perception). After these 1983 experiments, the Acoustics Laboratory has done a lot of scientific publications with auditory filter banks.
