Resumen:
To computationally simulate spatially distributed sound sources and achieve three-dimensional sound, head transfer functions (HRTFs) are used as filters. To complete a dense sphere of points with these functions around a subject, it is necessary to position a sound source at different angles and capture the impulsive responses using ear microphones. Currently, we are developing an individual HRTF measurement system that has a vertical semicircular support arc for loudspeakers and a controllable horizontal turntable where the subject is located. We have a turntable originally designed for another purpose and that supports up to 400 N of weight. In this work, it is proposed to redesign and optimize it to allow the movement of a seated person, tolerating up to ~2200 N. Based on tests carried out on the current platform, unwanted physical situations were detected and solutions validated through theoretical models and numerical simulations of static behavior were proposed.
