Yoichi Ando is a well-known architectural acoustician who employed genetic algorithms, acoustics, and psychophysical models of listener percepts and preferences to optimize the design of the Kirishima International Concert Hall in Japan. Ando’s recent book [Auditory and Visual Sensations, guest editor P. Cariani (Springer, New York, 2009)] summarizes decades of psychophysical experiments and neurophysiological observations (ABR, SVR, EEG, MEG). This paper will outline Ando’s psychophysics-based approach to architectural acoustics and his correlation-based theory of hearing and vision, along with supporting psychophysical and neurophysiological experimental observations. Ando proposes a temporally coded, correlation-based model of neuronal signal processing in which features of an internal autocorrelation representation subserve “temporal sensations” (pitch, timbre, loudness, duration), while features of an internal interaural cross correlation representation subserve “spatial sensations” (sound location, size, diffuseness related to envelopment). Together these two representations account for the basic auditory qualities most relevant for listening to music and speech in indoor performance spaces. Remarkably, Ando and colleagues have found many analogs of auditory percepts and preferences in vision. These include perception of the missing fundamental of flickering light as well as preferences for flickering lights, oscillatory movements, and texture regularity. Ando’s theory suggests possible common temporal processing mechanisms for hearing and vision.
