Design of virtual binaural manikins and auditorium acoustic modelling.

In this work a numerical model is applied in the development of the design of Virtual Binaural Manikin and Auditorium Acoustic Modelling. The binaural acoustic manikin is based in Human Thermal Modelling, using the Human Body Geometry Modelling, and the Sound Propagation Modeling numerical models. The Auditorium Acoustic Modelling considers the Auditorium Thermal Modelling, using auditorium geometry, and the Sound Propagation Modeling numerical models. The manikin and the auditorium geometry are developing with the Computed Aid Design, CAD, methodology. The Sound Propagation Modeling of the Virtual Binaural Manikin calculates the reverberation time and the Sound Propagation Modeling of the Auditorium Acoustic Modelling calculate the direct and indirect sound using the acoustic path. In this study an auditorium with a maximum occupation level of 168 manikins is developed. One manikin of the stage and three virtual binaural manikins in the audience was selected to be evaluate the acoustical path and reverberation time. The acoustic level, in the left and right ears, that the virtual manikins are subjected are evaluated. [ABSTRACT FROM AUTHOR]
