Motion Ambience

Ambience has been discussed throughout this iteration of the installation design in relation to sound and the environment its in but, the effect that motion or movement of people within the have upon has only been touched on. Motion of humans creates the ambient but also interferes with the environment as well in a physical. Movement of people creates sound and the ambient noise of which the installation is testing but, is there a connection between the amount of movement and the increase in sound levels.

A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The idea that sound moves in waves goes back (at least) to about 240 B.C. The Greek philosopher Chrysippus (c. 240 B.C.) these disturbances produce

Sound is produced by disturbances to an environment or medium by an object or movement of energy. This suggests that the more movement or disturbance cause the more noise is created. Ambient noise of an environment is created by sounds produced by objects within the environment. In summary this means that theoretically the more movement within an environment the more sound noise is created.

Motion is something that can be tracked with processing and Open CV library. The example sketch Frame Differencing looks a difference of frames and decides if there is moment and how much this is. This sketch could be used to decide weather there is any movement within a space mapping this to a value.

Taking this and implementing it within the design of the ambient sketch was relatively simple by taking the movement value of the images differences and mapping this to scale the height of a square, This compared to the average sound bar showed the change in amount of movement within the environment compared to the sound levels.

This connection between sound and motion is something that as a comparison between could prove effective as it adds a level of complexity to and second understanding of ambience.
