Figure 2
The bar graph compares the Z scores of healthier and less healthy choices under biophilic and non-biophilic sounds. The x-axis represents the type of sound, divided into biophilic sounds and non-biophilic sounds. The y-axis represents the Z score, ranging from -0.6 to 0.4. There are four bars in total, two for each sound type. The healthier choices are represented by grey bars, and the less healthy choices are represented by black bars. For biophilic sounds, the Z score for healthier choices is approximately 0.281, and for less healthy choices, it is approximately -0.105. For non-biophilic sounds, the Z score for healthier choices is approximately -0.481, and for less healthy choices, it is approximately 0.181. All values are approximated.Interaction sound × product category
