We all know how powerful sound is.
The question is, why?
It’s all about how it affects the brain and triggers our emotions.
How Sound Is Perceived By The Brain
The brain processes what we hear in waves. It translates impulses from the ear into sounds that we know and understand. When we hear, sound waves travel from the outer ear and then through the middle ear, where the sound vibration stimulates tiny hair cells.
The tiny hair cells in the inner ear send electrical signals to the auditory nerve that is connected to the auditory center of the brain where electrical impulses are perceived the brain as sound.
A previous study also showed that our hearing works the way our vision works, which has a strobe-like effect in the mind. It helps us focus on the most important sounds in the environment and at the same time, it can help us place sounds in the three-dimensional space.
Sound has a huge impact on us, humans. According to Margareta Andersson, Sound Architect at Lexter Sound Design in Stockholm, “When we lived outdoors, with the forest as our walls and the sky as our roof, we had to trust our senses to survive. Our eyes, taste buds, and ears told us what was safe or not—these so-called genetic memories still linger in our human DNA.”
Scientists also discovered that the brain does not have one special area to analyze music. Instead, different areas of the brain handle various aspects of a song, like a rhythm and tone. It is also noted that that sound or music is wired directly into how we feel.
