Concert halls are mainly designed to accommodate a range of music performances since different performances require different room acoustics characteristics. There is an increase in demand for multi-use concert halls which requires flexibility in the design elements. Some previous studies prove that by implementing passive variable acoustic solutions, acoustical conditions can be modified to make the venues compatible with various performance types. This study investigates the potentials of passive variable acoustic methods in symphonic music halls with a focus on Bilkent Music Hall in Ankara, Turkey. The methodology includes acoustical field measurements to test the effects of the existing variable acoustic system, which is in the form of operable/retractable wooden doors with fabric backing. Later, questionnaire/online surveys by musicians and music conservatory students to assess the subjective parameters in relation to objective parameter outcomes. The results of field tests indicate that current indoor acoustic condition of the hall is not satisfactory. The problem is specifically in mid to low frequencies in retracted state of the doors and high bass absorption in closed state. Future work will further assess the causes of the absorption by field test tuned simulations to discuss possible acoustical treatments.
