Science of Sound: Equal Loudness Curves

This video illustrates the usage of standard equal loudness curves, sometimes referred to as "Fletcher-Munson Curves", although the latter name is misleading. These curves allow for the translation of sound pressure levels measured in db-SPL into loudness levels measured in phons. References: Science, Waves & Sound Lecture Notes, section 9.
