This study aims to investigate the balance between speech intelligibility and privacy in museum environments using different acoustic scenarios.
Participants evaluated three acoustic scenarios derived from simulations of five museum galleries.
Scenarios included varying levels of material absorption and spatial configurations.
Two distinct audio reproduction settings were employed: a near-anechoic room and a panoramic visual environment.
Listeners preferred higher absorption scenarios with lower sound pressure levels at moderate distances (L p,A,S,4m).
Higher preferences were noted for configurations with steeper spatial decay rates (D 2,S), despite increased distraction distances (r D).
Findings contribute to enhancing acoustic comfort in museum designs while balancing privacy and intelligibility.
