## 1 Introduction  
The key principles of soundscape [1; 2; 3; 4; 5] have been developed within the ISO 12913 standard, with regard to its definition and conceptual framework [1], as well as data collection [6]. According to this standard, soundscape is \"the acoustic environment as perceived or experienced and/or understood by a person or people in context\". In other words, soundscape is defined as the way people perceive, experience, or understand the acoustic environment in a physical setting. Therefore, acoustic environment refers to physical phenomena, while soundscape is a perceptual construct [7]. Within this conceptual framework, soundscape is understood as highly dependent on the context [7]. Context is meant as the physical place where the acoustic environment exists and, according to the ISO definition, this \"includes the interrelationships between a person, activity and place, in space and time [... ] and may influence soundscape through (1) the auditory sensation; (2) the interpretation of the auditory sensation; and (3) responses to the acoustic environment.\" [1]. As [PERSON] and his colleagues stated in the first chapter of _Soundscape and the Built Environment_[3], context is a generic term that includes the non-acoustic components of a place (even a person's previous experience and memories) and plays a major role in the perceptual construction of an acoustic environment. However, as [PERSON] stated, this diagram is \"short on detail as to what those contextual components might be\". [PERSON] et al. [8] addressed this drawback and situated the environmental experience of sounds in public places firmly within an environmental people-activity-place framework [6]. This Environmental Experience Model has guided the methodological design and research presented in this paper. In accordance with this model, the perception of the acoustic environment in a specific place (soundscape) is defined not only by considering acoustic features, but also the physical context (characteristics of the place), and the interactions of people and the community with the place itself [8]. In recent years, the importance of context factors has been one of the most widely-discussed issues in the soundscape approach [1; 7; 8; 9; 10; 11; 12; 13; 14; 15]. Many studies conclude that elements related to the visual dimension, safety or cleanness, among others, are more relevant in the overall environmental experience of a place than acoustic parameters, particularly when considering soundscape and quietness. There are many references that highlight the relevance of context factors (e.g., landscape [9; 10; 11; 14; 15], geography and thermal conditions [16], maintenance, and cleanness [12]), and person- or community-related features such as culture and personal characteristics) in the soundscape approach, since these items have a remarkable influence on the perception process [1; 17; 18]. In addition, there is increasing evidence that the congruence between the different elements of a place is important in human preference [19], as well as how they influence the expectation of a place [20]. However, few studies have analysed the combined influence of these factors on soundscape [13; 21; 22]. Therefore, the challenge is to identify the relative importance of each one of them (when taken together) in order to find out the most influential and important variables when describing the experience that locals and visitors have in their interaction with a space and its sound. In a similar vein, a recent publication [23] explores the significance of a wide range of acoustic and non-acoustic factors in the soundscape of several public urban spaces in the city of Vitoria-Gasteiz (Spain). This work shows that the variable which best explains soundscape is the congruence between soundscape and landscape as perceived by the user of the place. Other relevant variables relate to the physical characteristics of a place, such as a person's perception of water or traffic, as well as an acoustic index associated with the acoustic climate (LA10-LA90).
