Psychoacoustic Analyses I

Psychoacoustics is the science of the relationship between physical quantities of sound and subjective hearing impressions. To examine these relationships, physical parameters, such as sound pressure level, frequency and modulation depth, are mapped to hearing-related parameters. Unlike the physical quantities, these hearing-related quantities – also referred to as psychoacoustic parameters – provide a linear representation of human hearing perception. This means that a doubling of a psychoacoustic quantity corresponds to a doubling of the corresponding subjective perception level. ArtemiS SUITE offers the possibility to calculate various psychoacoustic parameters. This Application Note explains how the psychoacoustic quantities loudness and sharpness can be calculated and used in ArtemiS SUITE.
