Performance of sound 2
Invisible Acoustics (Dagny Rewera, 2013)
This is Dagny Rewera recent invisible acoustics projects, it was inspired by cymatics, attempt to enlarging tiny sound waves by using a unique set-up including a series of speakers, a lens, and some soap bubbles. To make sound can be seen by human eye, Dagny Rewera developed an automated system that dips a hoop into a soap solution and holds it directly above the speaker. The soap bubbles vibrated with sound waves, and a magnifying lens is held above the iridescent bubbles and projected on the ceiling. Each speakers plays variety of different frequency ranges, which can producing different images by bubbles. Then viewer can see the ever-changing image that produced by sound. Rewera described this project " The aim of the project was to change the perception of the everyday… there might be more parallel worlds unnoticed in our mundane lives.” (2014)
Different with traditional experimental materials of cymatics such as liquid, sand or light, Rewera chose soap bubble to be a new transfer media, which created more subtle and colorful images to visualize sound.

Polifonia Liquida (Alessandro Perini, 2015)
Alessandro Perini designed a sound and light installation named ”polifonia liquida” exhibited at Inter Arts Center for the Gallery Night Of Malmo (Sweden) in 2015. He translated sound to light image very ingeniously. The work involves a series of 8 independent audiovisual systems, each one composed of a speaker inducing vibration into surfaces and a point light. The sound waves be visualized by the dynamic water, then the light and shadow magnified the image of water ripples.
Alessandro Perini has a strictly musical focus “the compositional process takes into account both the sound material and the visuals generated by sound” he explained. Therefore he have to balance the feeling of hearing and seeing. Because nice voices doesn’t necessarily look good.
