WOOd Flat Audio Panel System
In the last couple of years I have been experimenting with and building various sets of yellow cedar and maple flat audio-panels to create both instruments and audio diffusors that might engage in a more embodied form of listening and sound thinking. The LINKS below give an idea of the various explorations and implementation of these sound sculptures, and in general about the nature and spirit of these sound objects/instruments/resonators and my personal impetus behind them.
The cedar and maple flat audio-panels are built using large yellow cedar and maple boards reclaimed from discarded piles of wood in mill operations and drifting ocean logs on the Sunshine Coast of British Columbia. After being sliced and smoothly shaped, they are planed and sanded to thin them down to thickness ranging between 2/16”and 1/4” and finally mounted on a stabilizer wood stand.
An amplifier drives the sound into an audio transducer applied to the rear of each panel, exciting the wood boards and transforming their surface into a distributed-mode loudspeaker (DML). In this way the audio is approaching an omnidirectional presence in the way the sound from the cedar and maple panels is dispersed evenly in all directions.
The diffused radiation patterns of all frequencies created on the panels expands the audio source. Sound then propagates through the wood in the most liberated and natural way while becoming omnidirectional in the far field. The diffused sound is stunningly beautiful and softly filtered by the smooth quality of yellow cedar or the brighter resonating quality of maple, which adds to the uncanny character of their physical and sculptural presence.
In the Spring 2018 I will present an installation performance space at the Centre for Interactive Research on Sustainability (CIRS) at UBC with 16 panels driven by a 16-channel system. Both installation and performance instrument, WOOFAP / S will be also made available to a variety of local sonic explorers.
More details to come soon…
