Predicted speech privacy and distraction distances, the quality of speech intelligibility, and the diffuseness of the sound fields were observed. Within the past few decades, a new paradigm has emerged where reverberation control is not the only solution for good room acoustics. In certain open-plan office, quality of speech privacy and intelligibility should be similar for each workstation by creating a diffuse sound field. In many spaces, abfusor for absorption and diffusion are solution in a form of acoustic panel, furniture and other elements, such as bookshelves in offices. The measurement in this research utilized multi-microphones. The degree of diffuseness was done by evaluating the coherences of impulse responses measured. Values of T30, C50, and RASTI were also evaluated. Further analysis on the sound field diffuseness was done by evaluating the coherence of early and late reflections, and also occurrences of the comb-filtering effect. Subjective evaluation of selected workstations was also conducted. The methods utilized in this research demonstrate the ability for acousticians and architects to evaluate the effect of diffuseness on speech privacy and intelligibility quality of an open-plan office layout.[/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]Diffuse sound fields,ISO 3382-3:2012,Open-plan offices,Quality measurements,Reverberation control,Speech privacy,Subjective evaluations,Workstation[/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]ISO 3382-3:2012,Open-plan offices,Speech privacy,Workstation[/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]
