The reduction of aeroacoustic noise generated by pantographs has been an important subject of discussion in increasing the speed of Shinkansen trains. As the panhead significantly influences the aeroacoustic characteristics of the pantograph, reduction of its aeroacoustic noise is strongly demanded. This paper describes a method of evaluating the contributions of low-frequency aeroacoustic noise sources around the panhead. Visualization of these contributions can indicate the structure of such noise sources.
