Human-like Modulation SensitivityEmerging through Optimization to Natural Sound Recognition

Takuya Koumura, Hiroki Terashima, Shigeto Furukawa

This study shows that optimizing a neural network for natural sound recognition leads to human-like amplitude modulation sensitivity, suggesting evolutionary adaptation in auditory processing.

Visual discrimination of optical material properties: a large-scale study

Masataka Sawayama, Yoshinori Dobashi, Makoto Okabe, Kenchi Hosokawa, Takuya Koumura, Toni Saarela, Maria Olkkonen, Shin’ya Nishida

This study constructs a database of material images with annotated visual discrimination performance and shows that material discrimination depends on illumination and geometry, with individual differences in glossiness perception.

Deep, soft, and dark sounds induce autonomous sensory meridian response

Takuya Koumura, Masashi Nakatani, Hsin‐I Liao, Hirohito M. Kondo

The paper investigates factors affecting ASMR, finding that low-pitched sounds with dark timbre induce ASMR around 2 s after acoustic feature changes, and individual mood states influence the experience.

Cascaded Processing of Amplitude Modulation for Natural Sound Recognition

Takuya Koumura, Hiroki Terashima, Shigeto Furukawa

This study shows that cascaded processing of amplitude modulation in a deep neural network optimized for natural sound recognition mirrors neural representations in the auditory system.
