Even the most subtle sensory cues have a big impact on how people spend money. Recently, a team of researchers found that consumers associate higher frequency sounds with healthy food products. The respondents were asked to choose the food that best matched the sound they heard. Images of salads were more likely to be linked to higher frequency sonic logos.
Sensory stimuli, such as sounds and colours, play a prominent role in branding as they can invoke emotions which in their term drive brand loyalty. Next to that sound is the fastest human sense, faster than smell, taste, sight, and even touch. So if you’re aiming to sell healthy food consider using high-frequency sounds.
