By Yoichi Ando

Professor Yoichi Ando, acoustic architectural fashion designer of the Kirishima overseas live performance corridor in Japan, offers a finished rational-scientific method of designing functionality areas. His concept relies on systematic psychoacoustical observations of spatial listening to and listener personal tastes, whose neuronal correlates are saw within the neurophysiology of the human mind. A correlation-based version of neuronal sign processing within the vital auditory method is proposed within which temporal sensations (pitch, timbre, loudness, period) are represented via an inner autocorrelation illustration, and spatial sensations (sound position, dimension, diffuseness with regards to envelopment) are represented through an inner interaural crosscorrelation functionality. jointly those inner relevant auditory representations account for the fundamental auditory characteristics which are proper for hearing tune and speech in indoor functionality areas. saw mental and neurophysiological commonalities among auditory and visible sensations and choice styles are provided and mentioned. This booklet therefore spans the disciplines of physics, acoustics, psychology, neurophysiology, and track construction, thereby mixing technological know-how, engineering, and art.

2. Here the total pressure amplitude of reflection is given by A= [A21 +A22 +A23 + . . , 2000). The minimum value of τ e in a music piece is generally observed in its most active part, the part with the least redundancy, the sharpest musical contrasts, and the one that usually containing the most “artistic” expressive timing information such as vibrato or accelerando in the musical flow. Echo disturbances, therefore, are easily perceived in musical segments where (τ e )min occurs. Even for a long music composition, musical flow can be divided into short segments, so that the minimal values of (τ e )min of the ACF of the whole musical piece can be taken into consideration.

Waves I–V in ABRs are produced by near-synchronous firing of large numbers of neurons in the cochlea, brainstem, and midbrain. The later waves in this response reflect the contributions of binaural neural processing stations in the auditory brainstem. We found that the magnitudes of Wave IV on either side (IVl,r ) varied with the sound energies present at the entrances of the two ears. , 1991). Slow vertex responses (SVRs) are longer latency (10–500 ms) averaged auditory-evoked responses that are computed from scalp electroencephalogram (EEG) signals.

Signals were supplied to loudspeakers positioned at various horizontal angles (0–180◦ ) with respect to the front of the subject, all on the subject’s righthand side. The distance between each loudspeaker and the center of the head was kept at 68 ± 1 cm. The speakers had a frequency response of ± 3 dB for 100 Hz– 10 kHz. Left and right ABRs were recorded through electrodes placed on the vertex, and the left and right mastoids (Ando and Hosaka, 1983; Ando, 1985). Typical examples of recorded ABR waveforms as a function of the horizontal angle of sound incidence are shown in Fig.
