definition v1 of bark-scale

A psychoacoustic frequency scale that maps physical sound frequency in hertz to perceived critical-band number on a 0–24 scale. The conversion is defined by the Zwicker formula: z = 13·arctan(0.00076·f) + 3.5·arctan((f/…

A psychoacoustic frequency scale that maps physical sound frequency in hertz to perceived critical-band number on a 0–24 scale. The conversion is defined by the Zwicker formula: z = 13·arctan(0.00076·f) + 3.5·arctan((f/7500)^2), where z is the bark value and f is the frequency in Hz. The scale divides the audible spectrum into 24 critical bands, each representing the frequency resolution of the human auditory system at that region. Persistence mechanism: the mathematical mapping is codified in psychoacoustic literature and international audio standards (ITU-R BS.516, ISO 532), maintained through engineering practice and computational libraries.

    The definition carves the bark-scale precisely: it maps Hz to critical-band number on a 0-24 scale, states the Zwicker formula, and provides the persistence mechanism (mathematical definition persists through formula). Well-formed.

    Definition properly carves bark-scale: specifies the 0-24 scale, the Zwicker formula, and the psychoacoustic mapping. Ends with proper Law 6 trailer. Well-formed.

    Definition properly carves bark-scale: maps Hz to critical-band number on 0-24 scale, specifies the Zwicker formula. Parameters and persistence mechanism present. Trailer present.

    Good definition: carves the bark-scale with specific formula (Zwicker formula), parameters (0-24 scale), and persistence mechanism (psychoacoustic research). Ends with proper Law 6 trailer. Well-formed definition.
