In the present study, in order to explain the desirability of the soundscapes of the Timchehs of Tabriz Bazaar, Sound Pressure Level (SPL) and Reverberation Time (RT) have been measured as objective variables of acoustic behavior. Using descriptive questionnaire, subjective assessments were used to determine the quality of soundscape. The research seeks to answer the question of how the spatial characteristics of Tabriz Bazaar Timchehs affect their acoustic behavior and what factors are involved in the desirability of their soundscapes. Findings show that small-scale domes act as cavities with the retention of sound waves and have a good effect in reducing RT. Glass surfaces with sound reflection increase the echo of the environment and reduce the acoustic quality of the space. The materials used in Timcheh wall, brick with gypsum bonding, by diffusing sound waves play a positive role in acoustic quality. The results show that although the values of SPL and RT, which indicate the acoustical behavior of space, are somehow involved in the perception of people from the soundscape, but alone cannot be the basis for assessing the quality of the soundscape. The environmental characteristics and qualities of the spaces such as geometric proportions, dynamics or statics and the amount of congestion have a direct effect on the pleasantness of the urban soundscape in three Timches of Amir-e Shomali, Amir and Mozaffarieh. These three timches are part of tranquil spaces, and for this reason, the sudden appearance of some sounds, due to the difference in SPL, directly has a negative effect on the quality of the soundscape. Therefore, it is suggested that a component called Urban Soundscape Clarity be added to the studies in this field and be considered in the evaluation of soundscapes of tranquil urban spaces
