Abstract (in Japanese) (See Japanese page) 
(in English) This study investigates the technical feasibility of sound source distance estimation in acoustic communication. It discusses the difficulty of estimating the distance to a sound source based on a single feature, and examines a machine-learning-based approach. The results of evaluation experiments conducted through simulations are reported.
