| Abstract |
This study explores the use of on-stage reflectors to enhance stage acoustics for cello players in a circular 533-seat recital hall with an
unoccupied reverberation time of 1.31 seconds. Initial analysis suggested that the stage configuration could negatively affect acoustic
performance. To address this, measurements were conducted in accordance with KS F ISO 3382-1 standards, and a simulation model was
developed. Reflectors were designed with a focus on the 250 Hz band, considering the sound characteristics of the cello. Both ceiling and
movable reflectors were installed, and simulations were carried out by adjusting reflector height and the effective stage area. Lowering the
front and rear ceiling reflectors improved early sound strength in STEarly, while raising the rear reflector slightly increased late sound
strength on STLate, though the effect was minor. The rear ceiling reflector had a more noticeable impact than the front. For movable
reflectors, adjusting the distance from the stage led to improvements in STEarly, with limited effect on STLate. The most significant
improvement occurred when the reflectors were positioned at an optimal distance from the front of the stage. Future research should include
post-installation field measurements and auditory evaluations to assess the acoustic impact on performers. |
