Estimation method on sound qualities of machine noise is introduced that are mainly forcused on vehicle noise. Three factors which explain sound qualities of machine noise are powerfullness, comfortability and attribute related to booming noise. Comfortability is closely related to roughness. Roughness is the feeling caused by fluctuation of the time envelop of the sound and is well predicted by roughness level proposed by the author and other predictors such as roughness and fluctuation strength as well. Roughness level is calculated from the time envelop spectrum of the sound and expressed in dB. What is left in the future to complete estimation method on sound qualities of machine noise is to proceed more about the quatification of subjective impression of sound on the booming nature.
