Exploring Individualization of Sound Stimuli

There is extensive literature on the effects of binaural beats on cognitive states, however, the findings are often contradictory. This inconsistency may be due to the use of fixed, high-pitched frequencies in experimental protocols, which can make the sounds unpleasant to listen to. The aim of this article is to explore the individualization of spatialized sounds. To do so, participants were asked to create a sound of their choice by selecting both the fundamental and beat frequencies. We examined different types of sounds, including monaural and binaural beats, panning beats, and alternate beeps. The results reveal individual variability in the perception and preference of sounds, although some general trends emerged, such as a preference for low frequencies. Each type of sound evoked specific imagery, ranging from mechanical objects to atmospheric scenes, highlighting the importance of emotional and symbolic dimensions in studies of human auditory perception. In conclusion, these preliminary findings support the idea that, in the absence of universal rules regarding sound preference and perception, an individualized approach could offer deeper insight into the effects of binaural beats on cognitive states.
