Piezo-electric transducers (i.e. contact microphones) are incredibly versatile and inexpensive devices. Because they convert sound waves in a dense medium (such as wood or metal) into an audio signal, they are capable of revealing frequencies and complex sounds which would be otherwise inaudible to the human ear.

This recording was made along a remote stretch of beach near Wirrina Cove. At a couple of points along the beach, there are old ruined fencelines which run down the steep slopes leading down to the rocky beach. The fenceposts are ravaged stumps, worn away and potmarked from decades of exposure to the harshness of winds and salty ocean air. What remains of their fencewire is rusted and gnarled; thrown into uneven, twisted and overlapping patterns.

In spite of their ruination and 'silenced' appearance, when a contact mic is attached to a fenceline, a complex array of sonic activity is revealed. In windy conditions this particularly pronounced. One the one hand, the wind's shearing across the wires causes a whistling resonance to be heard; whilst the slackened, overlapping wires will strike and rub against each other, resembling percussive qualities.
