Data obtained based on direct measurements and analyzed using anthropometric theory and theories related to acoustics. the results obtained  that the auditorium chairs have been designed according to Indonesian standards. So that in terms of anthropometry, chairs are comfortable to use for a long time. If the auditorium chairs are analyzed using literature related to acoustics, they meet the standards. However, there are some inconveniences when the auditorium is used for events. Audience who were in the front row to the middle on the left and right corridors complained that the sound was too loud to make the chairs they were sitting on vibrate. In addition, the vibration of the seats is felt when other audience pass by in the corridor.
