Critical-band rate is measured in Barks, ranging 0 to 24 across the audible spectrum.

Evidence

The scale produced in this way is called critical-band rate. It grows from 0 to 24 and has the unit “Bark” (in memory of Barkhausen, a scientist who introduced the “phon”, a value describing loudness level for which the critical band plays an important role). The relation between critical-band rate, z, and frequency, j, is important for understanding many characteristics of the human ear. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
