Toyota and Honda’s NVH labs in Aichi Prefecture have published papers comparing "Japanese Sone 153" metrics for electric vehicle (EV) warning sounds. Since EVs are quiet, regulators in Japan mandated artificial driving noises. The baseline was set at 0.5 sones for idling, but the upper limit for pedestrian warning tones (200–500 Hz range) was capped at 153 milliones to avoid startling elderly pedestrians. This bespoke unit appears in JIS D 1024 (Measurement of interior vehicle sound). japanese sone 153

The rise of Sone 153 has also sparked discussions about the intersection of technology, art, and human intimacy. As our understanding of sound, psychology, and neuroscience evolves, we may see new applications of Sone 153 in fields like therapy, education, and marketing. (SONE-153)=> Saika Kawakita
