Nowadays, open plan office is preferred because it provides many advantages such as working mobility and increasing teamwork between co-worker and managerial. This concept also fulfills today energy management issues. Open plan office provides minimum energy consumption especially in lighting and air conditioning. On the other hand, a problem that usually faced by worker whose work in open office plan, which has correlation in speech comfort, are audial interference caused by another sound or noise, and loss of speech privacy. One way to overcome this problem is by applying absorber – diffuser (abfusor) surfaces. In this paper, simulation of abfusor application in an open plan office model was done by using finite element and ray-tracing method. The simulation was carried out with the reference of ISO 3382-3:2012 for Open Plan Office – measurement of acoustic parameter. Parameters that were varied in this simulation include absorption coefficient, scattering coefficient and the formation of abfusor surfaces. In situ measurements in the real Open Plan Office which was modeled in the simulation were conducted to provide comparison to the based model. The Simulation was used to determine the parameters of abfusor which provides optimum values to increase speech privacy and speech intelligibility for the open plan office model.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Abfusor,Absorption co-efficient,Acoustic parameters,In-situ measurement,Minimum energy consumption,Open-plan offices,Ray-tracing method,Scattering co-efficient[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Abfusor,Finite element method,Intelligibility,Open plan office,Privacy,Ray tracing method[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
