“…Of the 42 subjects, one had to go to a Taekwondo class and failed to complete all the experiments due to time conflicts, so the data of a total of 41 subjects were collected. A database containing the final results was created using IBM SPSS 25.0 [27,31,50,51] to evaluate the effect of different types of alarm sounds on the risk perception of the children in the evacuation experiments.…”

Due to differences in cognitive ability and physiological development, the evacuation characteristics of children are different from those of adults. This study proposes a novel method of using wearable sensors to collect data (e.g., electrodermal activity, EDA; heart rate variability, HRV) on children's physiological responses, and to continuously and quantitatively evaluate the effects of different types of alarm sounds during the evacuation of children. In order to determine the optimum alarm for children, an on-site experiment was conducted in a kindergarten to collect physiological data for responses to different types of alarm sounds during the evacuation of 42 children of different ages. The results showed that: (1) The alarm sounds led to changes in physiological indicators of children aged 3-6 years, and the effects of different types of alarm sounds on EDA and HRV activities were significantly different (p < 0.05). Skin conductance (SC), skin conductance tonic (SCT) and skin conductance level (SCL) can be used as the main indicators for analysing EDA of children in this experiment (p < 0.05), and the indicators of ultralow frequency (ULF) and very low frequency (VLF) for HRV were not affected by the type of alarm sounds (p > 0.05). (2) Unlike adults, kindergarten children were more susceptible to the warning siren. The combined voice and warning alarm had optimal effects in stimulating children to perceive risk. (3) For children aged 3-6 years, gender had a significant impact on children's reception to evacuation sound signals (p < 0.05): Girls are more sensitive than boys in receiving evacuation sound signals, similar to findings of studies of risk perception of adult males and females. In addition, the higher the age, the greater the sensitivity to evacuation sound signals, which accords with results of previous studies on the evacuation dynamics of children.

“…Although the very large number of stimulus conditions (N = 129) that were assessed in their study makes the drawing of any simple conclusions difficult, taken together, the complex array of significant findings reported nevertheless clearly do suggest that sound and scent can interact in terms of influencing people's evaluation of urban design (see also Ba and Kang, 2019b). Ba and Kang (2019a, p. 314) concluded that: "For the overall evaluation, in the presence of birdsong and low-volume sound, the overall evaluation was unaffected by odor; for other combinations of sound and odor, with increased concentration, the overall evaluation improved.…”

The majority of the world's population now lives an urban existence, spending as much as 95% of their lives indoors. The olfactory atmosphere in the built environment has been shown to exert a profound, if often unrecognized, influence over our mood and well-being. While the traditionally malodorous stench to be found indoors (i.e., prior to the invention of modern sanitation) has largely been eliminated in recent centuries, many of the outbreaks of sick-building syndrome that have been reported over the last half century have been linked to the presence of a strange smell in the environment. At the same time, however, there is also growing evidence that consumer behavior can be manipulated by the presence of pleasant ambient odors, while various aromatherapy scents are said to improve our mood and well-being. This Anglophone review focuses primarily on indoor western urban developed spaces. Importantly, the olfactory ambience constitutes but one component of the multisensory atmosphere and ambient odors interact with the visual, auditory, and haptic aspects of the built environment. Surprisingly, the majority of published studies that have deliberately chosen to combine ambient scent with other sensory interventions, such as, for example, music, have failed to increase store sales, or to enhance people's mood and/or well-being, as might have been expected. Such negative findings therefore stress the importance of considering multisensory congruency while, at the same time, also highlighting the potential dangers that may be associated with sensory overload when thinking about the effect of ambient smell on our well-being.

“…This is probably due to the psychological influence of vegetation (people feel good and safe among greenery), as also observed by Brambilla and Maffei [104] and Van Renterghem [62], who showed the importance of the compliance of sounds heard in parks with the expectations of visitors and audiovisual interaction with regard to the sound pressure level. Moreover, the smell of trees may play an important role in the perception of noise [105]. This factor, however, was not taken into account in the research conducted in the parks in Olsztyn.…”

Soundscape analyses and noise measurements should be a part of pre-design works involved in planning green areas in city centers. The aim of the study was to conduct a multi-criteria analysis of the soundscape of three parks in Olsztyn (Poland) as a part of the landscape planning process to determine the directions of re-design of places most exposed to noise. The research included: 1. functional and spatial analysis of the park surroundings in reference to the city environment, 2. analysis of the acoustic map, 3. measurements of sound pressure levels (SPL) at selected points in two periods (leafless and leafy), 4. analysis of characteristic sounds, 5. interview with park users and preparation of a mental map. The results of research regarding the perception of the soundscape of all three parks by respondents differ slightly from the results of both the acoustic map and SPL measurements. The results also confirm the difference between SPL in the leafless and leafy period. Places most exposed to noise are located at the park boundaries along the main access roads, and at park entrances. Recommendations and sample solutions are proposed, based on two suggested design activities, namely the reduction of undesirable sounds, and introduction of desirable sounds to the parks.
