The weighted-moment sharpness formula matches measured sharpness across diverse sounds

Evidence

Many psychoacoustically measured sharpnesses of different sounds have been compared with calculated sharpnesses, using the above formula. The agreement of the two is good in view of the relative simplicity of the equation. Three examples of the use of this model may be discussed. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
