A Study on Interior Acoustic Control Using Psychological Information

―Fundamental Consideration on Compact EV by measuring EGG―

Abstract

Since the ultra-compact electric vehicle does not generate an engine sound, indoor noise and wind noise due to road noise have a great influence on the comfort of the room. Previous studies have been studying basic examination of masking which is a method of noise control. In this study, brain wave measurement is performed focusing on the relation between bpm of music for masking and the heart rate of an occupant. At that time, we study the evaluation of comfort in the passenger compartment and trend of various occupants by EEG measurements. During the experiment, we are using a driving simulator to simulate the actual driving situation.
