The personal quality of sustained vowels uttered by eight male talkers was represented multidimensionally in a psychological auditory space (PAS) by means of Kruskal’s multidimensional scaling procedure based on the perceptual confusion in talker discrimination tests. Physical properties of the vowels were analyzed in terms of elementary acoustical(More)
We partially characterized the transferrin-independent iron uptake (Tf-IU) of neuronal and glial cells in the previous report. In the present study, we further examined a mechanism of which glial cells protect neuronal cells against iron stress using neuron-microglia (N-MG) and neuron-astrocyte (N-AS) co-cultures. When each solely purified cell was treated(More)
A new method of designing a microphone array with two outputs preserving binaural information is proposed in this paper. This system employs adaptive beamforming using multiple constraints. The binaural cues may be preserved in the two outputs by use of these multiple constraints with simultaneous beamforming to enhance target signals is also available. A(More)
BACKGROUND Pollens from species of the Cupressaceae family are one of the most important causes of respiratory allergies worldwide. Many patients with pollinosis have specific IgE to both allergens from Japanese cedar and Japanese cypress pollen. We set out to identify T cell epitopes in Cha o 2, the second major allergen of Japanese cypress pollen. (More)
To add to the database and to help clarify the overall shape and spacing of the equal-loudness relations at high frequencies, inter-frequency loudness matches were obtained for high-frequency pure tones. Between 1 and 10 kHz, a linear matching function with a slope of 1.0 gave a good account of the results. Above 10 kHz, the loudness-matching functions were(More)
The purpose of this study was to determine the binaurally perceived modulation depth (m) of the low rate amplitude modulated (AM) signals, under conditions of their dichotic presentation, i.e., when the AM signals presented to the left and the right ear had different modulation depths. The modulation depth was determined as a point of subjective equality(More)
