中文摘要:
      对大中型报告厅的室内音质缺陷和相应声学改造原则进行了初步分析和探讨。通过对工程实践的总结,得出了6种适用于大中型报告厅声学改造的技术措施,确保了在声学改造时,既不降低原有的室内美学品质,又满足室内声学的要求。同时,部分声学改造技术已应用在重庆市渝州宾馆中华厅的声学改造实例中,改造后的混响时间、声场不均匀度均得到了明显改善,良好的声学效果也表明了该技术措施的适用性。
英文摘要:
      This paper analyses and discusses the indoor acoustic defects and the relevant refurbishment principle of the large and medium sized lecture halls. Based on the previous practical projects, six types of appropriate technologies for acoustic refurbishment of large and medium-sized lecture halls are summarized, and they can fulfill the requirements of good acoustic quality without sacrificing its original interior aesthetic quality. Some of those acoustic technologies have been successfully applied in the refurbishment project of the Zhonghua Hall of Yuzhou Hotel in Chongqing. Given the significantly improved reverberation time and sound distribution, the applicability and effectiveness of the above technologies are demonstrated.
