摘　　要：通过对指挥大厅进行体型分析和混响时间计算,分析其存在的声缺陷,结合指挥大厅使用功能确定音质设计指标。依据装饰效果和声学材料特性,在大厅各界面布置合适的吸声材料,在消除厅内声缺陷的同时,确保音质指标满足使用要求。通过视线分析调整显示屏高度和座席排布,确保指挥大厅内有良好的视觉效果。通过合理的扩声设计,确保指挥大厅内有良好的声环境。后期现场实测数据表明,音质客观参量处于设计范围值内,能够满足使用要求。By analyzing the shape of the command hall and calculating the reverberation time,the existing sound defects are analyzed,and the sound quality design indicators are determined based on the functional use of the command hall.Based on the decorative effect and acoustic material characteristics,appropriate sound-absorbing materials are arranged at each interface of the hall to ensure the elimination of sound defects in the hall while meeting the sound quality requirements.Adjust the display height and seating arrangement through visual analysis to ensure a good visual effect in the command hall.Ensure a good sound environment in the command hall through reasonable sound reinforcement design.The on-site measurement data in the later stage shows that the objective parameters of sound quality are within the design range and can meet the usage requirements.
