Excessive sound from human conversation is considered as unwanted noise. Activities within the ICU requires the staff movements, which also creates non-stationary conversation area especially near the patient’s bed. Despite of this condition, nurse station is the location where the noise produced from conversation will raise significantly and where lack of speech privacy becomes a concern and higher chance of less confidentiality of medical information. The research is based on computer modeling that enables inclusion of scattering effects. By principle, the acoustical treatment in a nurse station is to avoid speech leakage from this area as well as to improve the speech intelligibility. Several improvement ideas is by installing hanging abfussor at the nurse station, hanging abfussor near the patient bed, and a glass partition at the nurse station. The speech privacy distance (rP) and distraction distance (rD) can be predicted using ISO 3328-3:2012 method and %Alcons formula based on the STI values. To evaluate the effectiveness of the improvement, an auralization scenario of the activities within the ICU is used in a survey. All the improvement design proposed did not create significant impact to the acoustic quality based on the rP and rD values. However, this paper demonstrates a good technique to predict the range of easiness of nurses’ communication in their workspace while they continuously move. It is given by the distraction distance that is used here to predict speech intelligibility of certain source to receiver distance. The result is a guideline for nurse station design optimization using three design approaches above by utilizing abfussor (absorber and diffuser) as part of the building interior.[/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]%Alcons,Acoustical treatment,Design considerations,Design optimization,Distraction distance,Medical information,Scattering effects,Speech privacy[/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]%Alcons,Distraction distance,Hospital,Speech privacy distance,Sti[/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]
