Between Phonautograph and sound sculpture, I was to build a much simpler device that produce both sculpture and also a performance. I had been researching on Cymatic and Canorgraphy that revolve around visual sound and decided to test on strings. The use of strings are to see the form and behaviour of sound wave from different kind of sounds played through the subwoofer. I’m testing the device on a few variables in order to explore further which to be put in proper index so that it is easy to be read and notated :
- Length of strings
- distance between one end to the woofer
- type of strings used
- different sounds
- tension of strings
I’m still working on device making cause it kinda took a while to figure out how the whole machine works since I only came up with this idea last Sunday. These are only a few testings I did last few days which I tested multiple strings taped on one speaker and another end of string to another side. I played the Janet’s audio to see how it went and recorded it through photos and video recording.
First test. The distance for this one is just about 150mm without fixed tension of string and the type of string used is cooking string which has less small strands of thread sticking out and have smooth form.
The outcome results shot in photos. The shutter speed of camera and the position of camera also plays a role in capturing the wavelength of the sound wave.
The exploration of this device pretty much inspired by the study of Leon Scott’s (first to come up with recording sound; ‘Phonautograph’) on ear canal and how it works as sound wave hit the the eardrum. This study also led him to his invention. What I found was, this device is too, carries similar function of ear canal.
It is much explored later on, on how sound moves, vibrate and the visual appearance of wave in so many ways and developed softwares.
This is just a small understanding on how sound waves move and how it leads from the graphic representation of first diagram to second diagram which further understood as how sound wave behaves. The low frequency (bass) create bigger gap of loop which means less sound waves traveled while high frequency create smaller gap with more loops as in more sound waves traveled. Of course, this is just a very small understanding of sound waves travel.
Apologize for such small updates. It is still in soooo much of progress. Hopefully can get it organized and presented by next Tuesday.
