P02-1 Comparison of Recording Techniques for 3D Audio Due to Difference between Listening Positions and Microphone Arrays—Toru Kamekawa, Tokyo University of the Arts - Adachi-ku, Tokyo, Japan; Atsushi Marui, Tokyo University of the Arts - Tokyo, Japan
The listening experiments comparing three recording techniques for 3D audio, namely Spaced Array, One-point Array, and Ambisonics were executed. First, the evaluation attributes were extracted referring the Repertory Grid Technique. Then participants compared the differences between these microphone techniques including the difference in listening position. From the results, the difference depending on the listening position is the smallest in the Spaced Array. Besides, it is estimated that Ambisonics gives the impression of “hard,” One-point Array gives “rich” and “wide,” and Spaced Array gives “clear” and “real.” Furthermore, “real” was evaluated from the viewpoint of clarity and the richness of reverberation, with a negative correlation with the spectral centroid and a positive correlation with the reflection from lateral and vertical, respectively.

P02-2 [moved to Session 8]—N/A
P02-3 Investigation into the Influence of Electromechanical Characteristics of Electrodynamic Transducers on Sound Quality Perception—Semyung Son, Hyundai Mobis - Yong-in, Kyung-ki, Korea; Juyoung Jeon, Hyundai Mobis - Yong-in, Kyung-ki, Korea; Junbae Choi, Hyundai Mobis - Yongin-si, Korea; Mikhail Pakhomov, SPB Audio R&D Lab - St. Petersburg, Russia
The two most noticeable types of distortion in an audio signal path—frequency and nonlinear—are frequently analyzed by researchers and developers in terms of auditory perception. The effect of transient distortion, though insufficiently studied, is evident in subjective listening tests when comparing loudspeakers with similar frequency response and no audible nonlinear distortions. In the present study we conducted loudspeaker measurements and subjective evaluations to define the critical factors based on the loudspeaker’s electromechanical characteristics that affect transient distortion and determined relations between the factors’ values and subjective scores.
