The bazaar is a key element and a perfect example of the appearance of historical cities, and its soundscape is of particular importance as it contains emotional and perceptual signs that were current in a specific place and time. This article examines the changes in the soundscape of the Tabriz bazaar in the historical course before the modern period. This article uses the library method and analyzes information from travelogues, historical maps of Tabriz, government documents and reports, etc. related to pre-modern historical periods as basic data and analyzes it according to the components of Schaefer's soundscape theory. The results show that the soundscape of the Tabriz bazaar in historical periods has more meaningful sounds than similar environments in the same period, and the same problem is still valid today. Also, components such as user activities such as mosques and tombs, baths and zurkhaneh, established and non-established businesses, vendors, social events, the presence of travelers and people's entertainment, the presence of different dialects and accents, the sound of construction, the presence of natural elements in the market environment, and sounds related to the management and maintenance of the market were key pieces of sound that were readable from a historical acoustic perspective, and the continuity of the readable acoustic landscape throughout the market indicates that the environment was dynamic.
