Indoor soundscape design of autonomous vehicles that comprehensively applies acoustic characteristics of architectural space type

Abstract

According to the paradigm shift in the indoor space design of future autonomous vehicles, the indoor space of the vehicle was classified according to the purpose of use and the optimal soundscape design for each type was proposed. The vehicle selected for the measurement can be the basic type of future autonomous vehicles, a relatively wide van suitable for building space investigation, and the space target was selected as spaces for listening to music, working (meeting), and resting. Accordingly, for the soundscape design, an audible sound source was produced and used for evaluation by conducting a sound field survey and computer simulation inside the vehicle. The indoor soundscape of the vehicle was evaluated by providing binaural sound source in the auditory test environment. The evaluation indicators were selected based on the indoor soundscape parameters in the architectural spaces such as concert halls and office buildings.
