The Fletcher-Munson curves are one of many sets of equal-loudness contours for the human ear, determined experimentally by Harvey Fletcher and Wilden A. Munson, and reported in a 1933 paper entitled "Loudness, its definition, measurement and calculation" in the Journal of the Acoustic Society of America.

I've heard that I can set the Fletcher-Munson curve for my RODE Nt1 microphone to compensate some frequencies (harshness, hi's)..

Is it true and does someone know more about this?

I've heard that those curves and settings exist for all marks of mic's..
