Split-based physicist Ivica Puljak provided an expert explanation ahead of the anticipated concert by Bruno Mars, focusing on the physical and neurological effects of the musical experience. Puljk detailed how specific sound waves interact with the human body, offering a scientific backdrop to the popular musical event.

In his presentation, the physicist explained the mechanisms by which music affects the brain and body of the audience. He paid particular attention to the phenomenon of low frequencies, explaining why powerful bass is perceived as a physical vibration in the chest, rather than merely as sound heard by the ears.

Through his scientifically grounded analysis, Puljak sought to answer why the hearts of the audience would beat closer together. This linked physical laws with the emotional and social aspects of the shared experience of music, offering a unique insight into the psycho-physiological responses of the audience.
