All Rights Reserved.Celempungs are one of the bamboo musical instruments that are made in West Java. Celempungs are always played in ensemble with another bamboo instruments or ensemble with the instrument itself. It is important for the musicians in ensemble to hear one-self and hearing each other simultaneously for a particular musician layout performance. Typically, celempungs are played at outdoor stages but riser stages are recently adapted for the music performance. Hence, it is instructive to study further the stage acoustic parameters for celempung music performance where the indoor, shoebox, and large space geometry are considered. Geometrical models were developed for two kinds of stage, namely front stage configuration and center stage one while the ray tracing method was employed to calculate the acoustic parameters, STearly and STlate. The other parameter such as T30, C80 and sound strength G are also studied in order to see the relevance with the stage support parameter. It is important to also know these parameters because the audience is expected to hear almost the same sound with the musician at the stage. It is found that for the case of the front stage, the result shows that the parameters are closed to the recommended value of STearly and STlate, -11 dB to -13 dB. Meanwhile, the acoustic parameter of center stage is more unfavorable than that of the front stage type. The T30 values are still higher than the preference once for both the front and center stage. Likewise, the clarity index C80 and sound strength G values differs from the preferable values. Hence, the mutual hearing indications can be found in the stages but that does not mean that the clarity and acceptable reverberant of the music are present as well as the loudness. In the other case, sound strength G is more favorable in the audience area rather than the stage area.[/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 parameters,Clarity index C80,Geometrical models,Music performance,Ray-tracing method,Recommended values,Stage acoustics,Support parameters[/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]Celempung music performance,Center stage,Front stage,Stage acoustic parameter[/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]
