ABSTRACT: As cities become more and more crowded, urban environmental noise increases. This paper discusses the practical recognition of the Mashhad MELAT Park sidewalk's soundscape. The purpose of this study is to answer the question of the Mashhad MELAT Park sidewalk's soundscape in people's minds. On-site sound recordings have been collected from the 1s t of November, December, and January of 2022 in consecutive places on Mashhad MELAT Park sidewalk and EMAMAT Boulevard. Sound and soundscape are sense stimulants that impact on quality of urban spaces. Sound, as one of the inseparable parts of the urban atmosphere, influences individual behavior, choosing the urban space, staying or passing by, perception of people from urban space, and overlay it influences the quality of urban spaces. Nowadays, variety and increasing sound sources from traffic, human activities, and disturbing sounds have created unpleasant soundscapes, leading to unclear sonic perception in citizens. The research is applicatory and descriptive-analytical. Data collection tools were done through sound walking (recordings for sound walking were up to 5 meters in dB by Calibrator S t-8851 sound meter device for numerical analysis), photography, and questionnaires based on people's mental perception. The data analysis method was performed through SPSS Analysis, sound maps, and GIS maps for qualitative analysis. Surveys showed a lack of invigorating sound resources on this sidewalk, expressing the dominance of vehicle traffic horns over natural and people sounds. Concentrating on soundscape in urban spaces leads to achieving sustainable urban spaces.
