“…As the food industry advances, researchers have observed that consumer satisfaction with puffed-grain food quality highly depends on their perception of the level of crunchiness (Van Hecke et al, 1998). The pleasantness of consuming puffed-grain food can be regulated via acoustic signals (Lin et al, 2022). For example, a harmonious feeling between audio and food can enhance people's perceptions and evaluations of taste (Spence, 2020).…”

Puffed‐grain food is a crispy snack whose consumer satisfaction depends on snack crispness and crunchiness, which can be characterized by the sound and the acoustic signals of food breaking. This study aimed to evaluate whether acoustic characteristics can be used to predict the crispness of various puffed‐grain food. Sensory evaluation was performed on puffed‐grain products with varying hygroscopic durations and different types. The relation between sensory evaluation and acoustic characteristics of nine different types of food was examined. The Hilbert–Huang transform was used to perform energy segmentation of the acoustic signal of puffed‐grain food and observe its energy migration process. The results showed that energy release was more concentrated in the low‐frequency range for grain‐puffed foods with different hygroscopic durations. No notable correlation was observed between the low‐frequency interval and sensory crispness for the different types of puffed‐grain foods. However, the acoustic features extracted from their inherent low‐frequency intervals showed a significantly improved correlation with sensory crispness. Therefore, it provides a theoretical reference for applying acoustic characteristics to describe food texture.

“…Firstly, upon reviewing the previous studies (see Table 1), we discovered that the majority of them are focused on the influence of natural sounds on food consumption. These consumption metrics encompass the willingness to buy for organic and environmentally friendly foods (Spendrup et al, 2016), the perception of food flavors (Lin et al, 2019; Lin et al, 2022a; 2022b; Xu et al, 2019), the choice between healthy and unhealthy foods (Peng-Li et al, 2021), the liking and wanting of different flavors of healthy and unhealthy foods (Peng-Li et al, 2022), as well as the craving and intake of healthy and unhealthy foods (Michels & Hamers, 2023). However, it remains unknown whether natural sounds would influence the actual purchasing decisions of green products beyond the food category.…”

“…Secondly, previous research has found that natural sounds have an impact on various psychological and physiological metrics (see Table 1). These metrics include connectedness to nature (Spendrup et al, 2016), affective or emotional responses (Lin et al, 2019; Xu et al, 2019; Lin et al, 2022a; 2022b; Michels & Hamers, 2023), visual attention (Peng-li et al, 2021), heart rate (Xu et al, 2019), and more. According to attention restoration theory (Kaplan, 1995), natural sounds can mitigate the depletion of people’s attentional resources.…”

Despite extensive research on nudging techniques aimed at promoting green consumption, the influence of natural sounds on encouraging environmentally friendly behavior remains relatively understudied. It is valuable to examine how sounds matter in green marketing, as more and more firms are using background sounds in video advertisements. Drawing on the Stimulus-Organism-Response model, we propose that natural sound increase early attentional congruency associated with green products, thereby promoting customers' purchase of green products. To test on our theory, we conducted an experiment using an event-related potentials (ERP) method and employed a hierarchical drift-diffusion model (HDDM). The results show that compared with unnatural sounds, natural sounds not only increased the purchase rates for green products but also enhanced decision-making efficiency (drift rate) in favor of purchasing green products. Additionally, consumers also exhibited a reduced frontal early P2 wave (150-230ms) in response to green products under natural sounds, indicating that natural sounds increased the early attentional congruency associated with green products. More importantly, the early attentional congruency provides an explanation for how natural sounds nudge the efficiency of purchasing decisions for green products. This study thus contributes to the discovery of a new psychological path that helps deepen our understanding of how natural sounds can nudge green consumption. It also provides actionable implications for green consumption market managers.
