Waves is an interactive sound installation for public spaces that encourages
environmental reflection and social interaction in otherwise rather anonymous
urban sites, transforming them into meaningful places. Originally proposed
for urban wading pools in Toronto, Canada, the artwork consists of specially
modified buoys floating in small pools that enable participants to make
poetic and logical connections between water waves and sound waves.
Custom-prepared buoys swaying on the water's surface create unique sound
compositions generated by the energy of waves in a wading pool. The pool's
water surface in conjunction with the buoys, form an intuitive interface
for musical collaboration and experimentation, allowing participants to
work together in real time to create multi-channel sound compositions.
Each composition is unique as wading and splashing or rocking directly
influences the magnitude and frequency of waves in the pool. Alternatively,
when no intentional splashing occurs, the buoys will reflect their environment
by responding to the waves created by wind or through silence when the water
and air are calm.
An accelerometer in each buoy measures the magnitude of waves through x- and
y-axis position changes caused by the rocking back and forth of the buoy.
The accelerometer's readings are then converted into sound waves by a
microcontroller. Finally, the microcontroller's output is amplified and sent
to a speaker integrated into the buoy. Each buoy plays an electronically
generated tone that is modulated by water waves and thus reflects participants'
movements of the water and/or buoy.
The readings of the accelerometer are converted into variables that contribute
to the process of sound synthesis. These variables influence a tone's pitch,
tone shaping (filter types and settings) and volume (attack, decay, sustain,
release envelope). Each resulting tone is synthesized in real-time.
Distinctively unfamiliar electronic sounds mix with familiar urban sounds
such as footsteps, car traffic, airplane noise, pigeons and cell phone
conversations to form unique and constantly changing sound compositions.
For the work’s exhibition at the People, Art and Technology (P.Art.y)
festival in Seoul, Korea the artists used the airwaves (FM broadcasts from
the buoys to radio receivers mounted in the cityscape) to further carry
the buoys' sounds into an urban environment.
