• Among many auditory feelings for the car interior noise, the booming sensation is considered the most important nuisance to the passengers. Although there are many origins for the booming noise of vehicles in general, the most important one is the engine boom that consists of tonal components related to fundamental engine rotation and its harmonics including the firing frequency. Because the degree of booming sensation is increased when these tonal components are dominating in car interior noise, it is demanded to extract the aurally relevant tonal components only. Although the pitch extraction model based on the place theory enables to find aurally relevant tonal components, there is a difference between booming sensation and pitch perception according to a frequency change of the tonal component. In this study, a subjective listening test using a tracking method is performed to find the difference limen for just a noticeable change of booming sensation in frequency. By applying the resultant data and also the empirical data by Zwicker, the existing pitch extraction model is modified. This refined model and loudness analysis can be used for predicting the degree of booming sensation. [Work supported by the BK21 project and NRL.]
