This week's lesson is all about sound, how it works, and a lot of theory. Take EQ, Delay, Distortion and Chorus as examples. The basic usage and practice of cubic basis are also introduced. This week's assignment is to create a visual sound such as amplitude, frequency, and diffraction.
Acoustic resonance
It refers to the phenomenon that the amplitude of a sound wave is enhanced when it matches the natural frequency of an object within a certain range. When the natural frequency of the object is the same as the frequency of the sound wave, resonance occurs, which increases the amplitude of the object's vibration.
This experiment is very common, but the effect is very intuitive. In fluid art, beautiful patterns can be made by manipulating sound waves. And can save a lot of labor costs.
Experimental process
I used a Bluetooth speaker to play music with a distinct rhythm and inverted paper cups on top of it. A small amount of water is then used as a conductive medium to make sound waves appear. To test the effect of sound waves, I placed extremely thin pieces of paper on the surface of the water. As the sound waves changed, the water fluctuated in different ways, and the paper moved. At the climax of the music, the paper cup is overturned under the influence of the sound wave. At this point, the visualization of the music is complete.
