This study investigates the impact of audio semiology on consumer purchasing behavior within the Saudi Arabian market, focusing on how sonic elements such as tempo, cultural congruence, and background music influence decision-making. Drawing on semiotic theory, neuroscience insights, and sensory marketing research, the study employs a descriptive quantitative survey of 200 consumers in Jeddah. Data were collected through a structured online questionnaire combining demographic questions, shopping behavior measures, and controlled audio clip tests. The findings reveal that Saudi online shoppers are predominantly middle-aged, female, and highly educated, with frequent engagement in e-commerce focused on fashion, beauty, and groceries. Amazon, Noon, and SHEIN emerged as the leading platforms, reflecting trust and accessibility as critical drivers of platform choice. With regard to advertising, respondents expressed diverse preferences toward music: the largest group favored no music at all (28%), while many were open to any suitable type (26%) or global-Arabic hybrid styles (22%). By contrast, traditional Arabic music (12%) and modern Arabic music (12%) were the least favored. Overall, most respondents reported that music rarely influences direct purchasing, though disliked or intrusive soundtracks could deter engagement. This study contributes to the limited Middle Eastern literature on audio semiology by showing that minimalist and flexible audio strategies may be more effective than traditional approaches. It offers practical recommendations for marketers to align sonic branding with cultural sensitivity and consumer expectations in Saudi Arabia.
