MUIC & ACOUTIC – OUND PHYIC & PYCHOACOUTIC CALCULATOR
Bark Scale
A precise tool.
What is the Bark Scale & How does it work?
The Bark scale is a perceptual scale of pitch that was developed by Eberhard Zwicker in the 1940s to describe how humans perceive changes in frequency. It divides the audible spectrum into bands that are roughly equal in perceived width, unlike linear scales where the same frequency interval represents different perceived widths at different frequencies.
Bark = 13 cdot arctan(0.76 cdot f / 1000) + 3.5 cdot arctan(f^2 / (7500^2))
Bark = Bark scale value
f = Frequency in Hz
f = Frequency in Hz
This formula helps in understanding the psychoacoustic properties of sound, particularly in hearing and audio engineering applications where frequency perception is crucial.

Frequently Asked Questions
What is the Bark scale?
The Bark scale is a perceptual scale of pitch that describes how humans perceive changes in frequency, dividing the audible spectrum into bands of equal perceived width.
How do I use this calculator?
Enter the frequency in Hz to calculate its corresponding Bark scale value using Zwicker’s formula.
Why is the Bark scale important?
The Bark scale helps in understanding human auditory perception and is used in audio engineering, hearing science, and music theory.
What is the range of frequencies covered by the Bark scale?
The Bark scale covers the audible frequency range from about 20 Hz to 20,000 Hz.
Can I use this calculator for any frequency?
This calculator is designed for frequencies within the human audible range, typically between 20 Hz and 20,000 Hz.
What does the Bark scale value represent?
The Bark scale value represents the perceived width of a frequency band in the human auditory system, with each Bark representing roughly equal perceptual bandwidth.
