• This data shows the relationship between Brainwave and Sound frequency in six selected locations in London. It experiments to visualise the sound frequency of specific location and how it is transformed into brainwave, which influences the state of human brain, thus how we feel about the environment. This experiment was conducted with the curiousity of why we feel different about particular places. We see things through our eyes, hear sounds through our ears, and feel touch through our skin. The things we see such as colour, shape, and light play major part of how we feel the environment, yet what we hear is rather abstract and subconscious. This data intends to brings the emotional influence of sound around us to the forefront.
