Resonance Analysis

The image above lays out the audio responses (seen through a spectrogram) of each layer of plywood to different octaves of ‘A’ as an input signal. This analysis will provide the framework for informing the design of a table with surface speakers embedded throughout. By designing for varying thicknesses (and even materiality) different frequencies can be brought out, therefore equalizing output by design.

The table is a social object. It is an object which mediates between people, conversation, and action with objects placed on it. By turning a table into a speaker system it’s material resonances are made audible and influence the output of the input signal. The table also becomes tactile through audio output and puts a person touching the table into a direct relationship between their senses and the physical nature of the table. It also becomes an object which is experienced and manipulated collectively. For example, when people place their arms on the table, or add plates, cups, and other objects, they are inadvertently manipulating the audio and tactile output from the speakers.
