Arranging office space into a single open room offers advantages in terms of easy exchange of information and interaction among coworkers, but reduces privacy and acoustic comfort. Thus, the purpose of this work was to evaluate the acoustic quality of a real open-plan office and to propose changes in the room to improve the acoustic conditioning of this office. The computational model of the office under study was calibrated based on RT and STI measurements. Predictions were made of the RT and STI, which generated the radius of distraction r(D), and the rate of spatial decay of sound pressure levels per distance doubling DL(2) in the real conditions of the office and after modifications of the room. The insertion of dividers between work stations and an increase in the ceiling's sound absorption improved the acoustic conditions in the office under study.
将办公空间布置成一个单一的开放式房间，在信息交流和同事之间的互动方面具有优势，但会降低隐私性和声学舒适度。因此，本工作的目的是评估一个实际的开放式办公室的声学质量，并提出改变房间的建议，以改善该办公室的声学条件。基于 RT 和 STI 测量，对研究中的办公室的计算模型进行了校准。在办公室的实际条件和房间修改后，对 RT 和 STI 进行了预测，生成了分散半径 r(D)和每距离加倍的声压级空间衰减率 DL(2)。在工作站之间插入隔板和增加天花板吸声，可以改善研究中的办公室的声学条件。
