Different method has been developed to understand the soundscape in the laboratory using acoustic environment composition. The soundscape composition has been validated and implemented for outdoor urban soundscape but not the indoor soundscape. The previous soundscape simulator only considers the behaviour of sound sources (movement, and position in space) without considering the sound reflection. This study tries to develop an acoustic environment simulator for passenger train soundscape study. In the passenger train, there are some annoying sound source that cannot be removed such as the sound of bogie or the sound of buffers and chain coupler. The soundscape composition concept using acoustic environment simulator can be implemented to understand the existing soundscape, to fix the soundscape (by selecting different sound source for masking and adjust the sound level), and to evaluate the effect of the acoustic treatment inside the passenger train. The simulator can reproduce realistic acoustic environment using ambisonic reproduction concept. Furthermore, the reflection inside the passenger train simulated by using the concept of auralization.[/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]Acoustic environment,Acoustic treatment,Auralizations,Passenger train,Sound level,Sound reflection,Sound source,Urban soundscape[/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]https://doi.org/10.1088/1742-6596/1075/1/012045[/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]
