Research Abstract

A numerical simulation was performed to analyze an acoustic phenomenon around a head, especially an external ear, and subsequently to investigate what causes an inter-individual variation of acoustic signals observed at an ear-canal entrance. Results reveal the features of resonance modes arising in a pinna cavity for sound sources on the median sagittal plane. Furthermore, it is shown that upper details of a pinna play a crucial role in determining physical properties of the acoustic signal and sound localization.
