In addition to the common analysis methods with weighted levels, psychoacoustics offers analyses with so-called basic “sensation magnitudes”: “loudness” indicates for example how loud a noise is actually perceived to be, “sharpness” represents the perception of high frequencies in a signal, the magnitudes “fluctuation strength” and “roughness” provide information on the time structures of a signal. Using these and other sensation magnitudes, it is possible to describe and analyse perfectly both disturbing noise and target sounds for the humans’ perception .
