Sound Walk

On our sound walk, Will and I ventured over to the hill near the Davis Center Tunnel entrance on Main Street. While we were there we were very observant of the level of wind. The hill acted as a natural wind tunnel in that it focused the wind down towards Main Street from the Catholic Center near Redstone Campus. We discussed the idea that wind isn’t actually heard, it’s the motion caused by the wind that we then in turn perceive as audible signs of the presence of wind. A human beings “microphone” is deep within the ear so it is sheltered from the wind but the microphone used in my iPhone is almost directly exposed to the wind. It is then in turn heard as an overarching white noise in the recordings. Fortunately in reality, we humans are able to filter that out.
