“…This is consistent with the findings of previous studies on the physiological effects of nature-derived stimuli [32,37]. A similar finding was reported in a recent clinical study on patients hospitalized in a cardiac care unit; in the patient group that listened to natural sounds for 30 min, there were significant decreases in heart rate before and after the intervention [58].…”

Exposure to natural sounds is known to induce feelings of relaxation; however, only few studies have provided scientific evidence on its physiological effects. This study examined prefrontal cortex and autonomic nervous activities in response to forest sound. A total of 29 female university students (mean age 22.3 ± 2.1 years) were exposed to high-resolution sounds of a forest or city for 60 s, using headphones. Oxyhemoglobin (oxy-Hb) concentrations in the prefrontal cortex were determined by near-infrared spectroscopy. Heart rate, the high-frequency component of heart rate variability (which reflects parasympathetic nervous activity), and the ratio of low-frequency to high-frequency (LF/HF) components (which reflects sympathetic nervous activity) were measured. Subjective evaluation was performed using the modified semantic differential method and profiles of mood states. Exposure to the forest sound resulted in the following significant differences compared with exposure to city sound: decreased oxy-Hb concentrations in the right prefrontal cortex; decreased ln(LF/HF); decreased heart rate; improved feelings described as “comfortable,’’ “relaxed,” and “natural”; and improved mood states. The findings of this study demonstrated that forest-derived auditory stimulation induced physiological and psychological relaxation effects.

“…The PMR (37.80 ± 10.1) and PMR + NS (31.19 ± 6.15) groups had significantly lower mean postintervention SAI scores than preintervention scores compared with the control group (Table 3). There are studies on the effect of nature sounds and PMR alone or in combination with different methods on different populations 17,21,23,28,29,36 . Torabizadeh et al 17 investigated the effect of relaxation exercises and support groups on anxiety in nursing students and reported that both relaxation exercises and support groups had a significant effect on anxiety in nursing students but that relaxation exercises were more effective than support groups.…”

Purpose The aim of this study was to determine the effect of progressive muscle relaxation (PMR) and nature sounds (NS) on students' blood pressure measurement skills, anxiety levels, and vital signs. Design and Methods This randomized controlled study conducted at the nursing department of a university in February 2020. During skill training, one group was given PMR and one group was given PMR + NS. The routine teaching procedure was applied to the control group. Findings The PMR (37.80 ± 10.1) and PMR + NS (31.19 ± 6.15) groups had lower mean postintervention anxiety scores compared with the control group (40.86 ± 9.13). The PMR + NS group had higher mean postintervention knowledge test score than other. Practice Implications PMR + NS and PMR helped reduce nursing students' anxiety levels and pulse rates. PMR + NS helped increase their blood pressure knowledge test scores.

“…Furthermore,the acoustic environment is directly associated and highly influenced by the landscape structure (Liu et al 2014). Biological sounds emanating from soniferous species formulate a desirable soundscape with several co-benefits, including the connection of urban dwellers with nature (Spendrup et al 2016) and health restoration (Ghezeljeh et al 2017).…”

At an international level it is recognised that urban noise has serious and negative public health impacts. This leading editorial and the special issue it accompanies seeks to broaden this agenda. An important goal for Cities & Health is to give ear to new urban health topics, methods and collaborations. In doing so this paper presents the topic of urban sound and health from several unique angles. At its core, we deliberately move the focus beyond noise levels, as measured by decibels, and harm to health through the stress of relentless background noise. Instead, we focus on the concept of soundscape, a more qualitatively nuanced research subject of enquiry. The paper serves as an introduction to soundscape and health from several distinct disciplinary positions and lays a good intellectual foundation for the twenty-two papers published in this special issue. We hope that through a soundscape approach we can encourage fresh thinking about urban sound, including how people perceive and relate to their sonic environments, and show how sound can contribute to health. We believe that this approach can provide a collaborative platform for sound artists, sound technologists, urbanists and local people to work together with public health and create healthier urban environments.
