<p>This study examines how auditory rhythms operate as an analytical mechanism through which sonic identity is produced and stabilized in an urban bazaar. As one of the city’s historic and vibrant urban spaces, the bazaar possesses a soundscape that functions beyond an environmental backdrop, forming an integral part of citizens’ lived experience and collective memory. Adopting a qualitative approach, the research explores the sonic layers of the bazaar through field observation, audio recording and analysis, and semi-structured interviews. Data analysis was conducted at both technical and perceptual levels. At the technical level, RMS and Peaks indices were extracted using <i>Sonic Visualiser</i> to identify underlying rhythms and acoustic events. At the perceptual level, the interviews were analyzed using thematic analysis. The findings revealed that the sonic identity of the bazaar is shaped through the interaction of three primary layers: the rhythms of daily activities and commerce; natural rhythms generated by rainfall and climatic conditions; and linguistic and vocal rhythms rooted in local dialects and vendors’ calls. These rhythms fluctuate throughout the day, producing distinct patterns of spatial perception across different phases of everyday activity. Participants described the sounds of the bazaar as carriers of memory, emotional attachment, and indicators of the space’s vitality, and believed that their absence would diminish both the identity and liveliness of the bazaar. Moreover, the results indicate that sound in the Rasht bazaar constitutes a form of urban intangible heritage, playing a fundamental role in representing local culture, sustaining collective life, and shaping the urban experience.</p>
