The office space is considered as a single thermal zone with a single air conditioning treatment while daylight is capable to penetrate throughout the entire space. Despite of the benefits, transparent surfaces commonly are acoustically reflective and reduce speech intelligibility due to the excessive reverberation. Without room barriers, it becomes difficult to avoid unwanted noise from equipment such as copy and printer machines. Speech intelligibility improvement has the drawback in speech privacy quality for each Workstation where optimal distance between the Workstations is critical. The speech intelligibility of nine Workstations was observed using reverberation time, C50, and RASTI. Meanwhile, %Alcons was used to evaluate the speech privacy distances and distraction distances with T60 and STI as embedded values. The results of T30 indicate good speech intelligibility for the entire office. The drawback to that condition is low speech privacy and the poor ability to concentrate on work. The subjective evaluation also confirmed these objective measurements. The results demonstrated the ability of the method and techniques applied in this research to evaluate speech privacy and speech intelligibility of an open-plan office. The optimum background noise required to obtain both speech intelligibility and privacy can also be predicted. The techniques are expected to contribute for improvement of the ISO 3382:3-2012 (E) and other related Standard for acoustical measurements of an open-plan office.[/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]Acoustical measurements,Conditioning treatment,Intelligibility improvements,Method and technique,Objective measurement,Reverberation time,Subjective evaluations,Transparent surfaces[/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][/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]
