This situation leads bamboo to be material that commonly used for constructing various solid structures with particular strength including violin. It is interesting that bamboo violin has a unique sound quality that differs perceptually from common wooden violin. This research is focused on finding the physical parameters in order to get plausible explanations on that sound difference by conducting vibro-acoustic analysis. An automatic bow-moving machine is developed to provide a highly repeatable bowing strokes upon string. The frequency spectrum analysis is used.A piezoelectric is put on the violin resonator surfaces for recording excitation force of bridge while a microphone is used for recording sound pressure level produced by the resonator. This approach is considered in order to obtain frequency response function of soundbox as ratio of the sound pressure level to the vibration one. It is found that the frequency response function on overtones of both violins are different at mid and high frequencies. Meanwhile, at low frequencies it is seen that the both violins share similar pattern of frequency response function hill peaks.[/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]Frequency response functions,Frequency spectrum analysis,High frequency HF,Physical parameters,Sound pressure level,Vibro-acoustic analysis,Vibroacoustics,violin[/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]bamboo,vibro-acoustics,violin[/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/10.1016/j.proeng.2017.03.029[/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]
