In 1933, two researchers at Bell Labs—Harvey Fletcher and W.A. Munson—conducted one of the most significant experiments in psychoacoustics. Their experiment was based on a series of tests taken by a group of listeners. Each test involved playing a test frequency followed by a reference tone of 1 kHz. The listener simply had to choose which of the two was louder. Successive tests involved either a different test frequency or different levels. Essentially, what Fletcher and Munson tried to conclude is how louder or softer different frequencies had to be in order to be perceived as loud as 1 kHz. They compiled their results and devised a chart known as the Fletcher–Munson curves. A chart based on the ...
