All rights reserved.One of the method for reproducing soundscape is using headphone. The level of reproduction usually calibrated using dummy head according to the actual sound level. The actual sound level usually measured using measurement microphone or sound level meter which capture the sound from every direction. In contrast, the calibration for headphone conducted by adjusting the sound level on ears at the same level from the measurement microphone. This study tries to measure the level difference on reproduce soundscape using headphone based on the common calibration method. White noise is reproduced in a reverberation room and measured by a measurement and dummy head that has been calibrated. The measurement shows that the dummy head measured 11.1 dB lower than the measurement microphone. This study proposes a method for calibrating the headphone with the validation using semantic differential analysis. Furthermore, this study analyses the perception of sonic environment reproduction using headphone in two conditions: when the recording reproduced at 10 dB lower and when the recording reproduced at the correct level. Analysis using semantic differential analysis shows that when the sonic environment recording reproduced at 10 dB lower than the correct level, two soundscape dimensions shows: The combination of Dynamic and Communication (32%), and Relaxation (24%). When the sonic environment reproduced at the correct level, three soundscape dimensions similar to the actual soundscape occurs: Relaxation (36%), Dynamic (16%), and Communication (10%).[/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,Calibration method,Dummy head,Reverberation rooms,Semantic differential analysis,Sonic environments,Sound level meter,Soundscapes[/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]Acoustic environment reproduction,Dummy head,Headphone calibration,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=”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]
