Enhancing authenticity in historic districts via soundscape design

Abstract Historic districts play an important role in urban planning and protection. While previous research on soundscapes has focused on acoustic comfort or preferences in these districts, the aspect of authenticity has been somewhat overlooked. Therefore, this study proposes a methodology for constructing soundscapes that enhance the authenticity of such districts. Using the grounded theory approach, we identified four key components for enhancing authenticity via soundscapes: the aim of soundscape design, physical and cultural characteristics of soundscapes, the effects of soundscapes, and the influence of spatial characteristics on soundscapes. A theoretical framework was developed to illustrate the enhancement of authenticity in historic districts via soundscapes. To verify the applicability and advancement of the proposed framework, it was compared with methodologies and steps obtained from previous soundscape research in historic districts. This study underscores the significance of soundscape design in creating authenticity in historic districts, thereby contributing to the development of soundscape design in historic districts and offering sustainable solutions for the protection and renewal of urban cultural heritage.
