Evaluation of acoustic performance open-plan office at Jawa Pos building based on ISO 3382-3

Abstract

The acoustic performance of open-plan office has become an important topic for discussion along with the development of office centers in major cities in Indonesia, including in Surabaya. Acoustic problems at open plan office often arise, such as background noise and speech privacy. Based on ISO 3382-3 2012, an open plan office must meet certain standards to keep productivity and concentration. These parameters are Average A-Weighted Background Noise (Lp, A, B), A-Weighted SPL of Speech at 4 m (Lp, A, s, 4m), Spatial Decay Rate of A-Weighted SPL of Speech (D2,s), Distraction Distance (rD), Privacy Distance (rP). From measurement and calculation did to an office building in Surabaya obtained a value of Lp, A, B equal to 52 dBA, Lp, A, s, 4m 52 dBA, D2, S 4,19 dBA, rD 11,75 m, rP 23, 8 m, and STI at the nearest table 0.78. These results indicate that further acoustic treatment is required to meet the standards specified by ISO.
