In music schools, indoor sound quality is a crucial necessity since students and trainees are learning and improving their skills by listening to their own instruments or voices. Currently, the majority of music schools have sound absorbent panels on wall surfaces to adjust reverberation time (RT) in the practice rooms. However, misuse of sound absorbent panels may lead classical singing trainees to utilize improper technique since they adjust their voices to suit the acoustics of these rooms. This study investigates the optimum reverberation time (RT) for a room by varying the distribution and the number of sound absorbent panels to determine the classical singing trainees’ sound preferences along with their subjective assessment towards indoor sound quality. Three different room settings were determined according to the amount of reverberation time, consecutively (dead to live). The trainees sang vowels as high and as low as they could in each setting. Reference tones were presented by a piano shortly before producing each vocal sound. Data was taken from 30 classical singing trainees with an age range of 15 to 30 through questionnaires at Bilkent University, Faculty of Music and Performing Arts. Results have shown that the majority of trainees choose the dead room setting as the most preferable, which has a slightly dead reverberation time around 0.6 seconds.
