| Abstract: | When a laboratory at a technical college is used as a site for psychoacoustic experiments, there are objects in the experimental environment such as walls, floors, ceilings, and chairs that obstruct the propagation of sound waves, which may change the accuracy of sound direction localization by altering the sound waves reaching the listener's ears. Therefore, the purpose of this study was to clarify the effects of these environments on sound localization characteristics using simulations. In this paper, we evaluated the effect of the reflection of sound waves on a chair to keep posture of the subject on the sound image localization for several loudspeaker positions. Results showed that it isn't strongly possible that the early reflections due to the chair will clearly shift the direction of the sound image. |
