What is the result of binaural loudness summation?

Binaural loudness summation refers to the phenomenon where sounds presented to both ears are perceived as louder than when the same sounds are presented to a single ear. This effect occurs because our auditory system integrates sound signals from both ears, leading to an enhanced perception of loudness. This enhancement happens due to several factors, including the summation of sound intensity and improved signal-to-noise ratio when the auditory information comes from both sides. Thus, when sounds reach both ears simultaneously, they create an overall louder perceptual experience compared to listening with just one ear.
