In street design improvements, multifunctional spaces for activities and mobility are increasingly required. These spatial elements are perceived not only visual perception but also auditory perception, which makes soundscape important in street design. This study aims to clarify the impact of soundscape on street design evaluation using 3D street models and statistical evaluation models. First, a literature reviews classified components of soundscape on street into types of sounds. Then, 3D street models with sounds were constructed and applied to a questionnaire survey. Finally, regression models are developed to evaluate street design with soundscape. As a result, the evaluation was affected by traffic noises and activity sounds.
