Originally posted by dobro the 90 db curve doesn't seem any flatter than the 60 db curve so why not mix at 60 db and save your ears, like mixsit says it's not the flatness, it's the difference betwe.

What is wrong with the fletcher munson curves since the days of fletcher and munson we know that hearing doesn't function in a linear way and is determined by. Fletcher - munson curve == fletcher and munson were researchers at bell laboratories who demonstrated, in 1933, that the human ear (and brain) perceive different frequencies in a shifting manner dependent on level their measurements showed that your ear is most sensitive to frequencies in the range of 3-4khz, and that frequencies above and.

Fletcher-munson curves essay example 791 words | 4 pages scientists at bell labs, harvey fletcher and wilden a munson researched this process and what they discovered has changed and affected how we as humans understand the hearing process.
Fig 1: the fletcher-munson curves, or equal loudness contours, show the degree to which our ears are nonlinear with regard to frequency they favor upper-mid frequencies and struggle with quiet lows and highs. 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. Our perception of loudness varies with frequency and level as originally detailed by fletcher and munson (figure-1a), their ear-search at bell labs in 1933 generated the equal loudness curve. Sound-equalization in relation to the way we known as the fletcher-munson curves, 1 plots the proportional loudness of the way we hear sound frequencies.
