Preliminary Video Documentation (surface transducer test)

This is video documentation of a materiality with surface transducers (contact speakers). I was testing the different resonant properties of plywood and varying thicknesses. Analysis of the documentation will be coming shortly.

5 different tones were played through the speaker and tested on the different thicknesses. A computer running a spectrogram analyses listened to the resonating sounds being produced by the speaker vibrating the wood.

Tones:
110 hz
220 hz
440 hz
880 hz
1760 hz (1.7 khz)
