PSYCHOACOUSTICS

shaking nuts, bolts and springs on rods hanging from the
ceiling to create something akin to an eight-piece drum
kit. “Bringing sounds that people are usually not even
aware of to the surface,” he insists, “amplifies sound and
creates a whole new world.”
It’s a world he has longed for all his life. What with
cars, hip-hop and the experimental music scene, society is
already flooded with lower frequencies. But there is more.
It’s that depth of sound that attracted the father of one,
even as a toddler. “I used to press my head up against
washing machines and dishwashers,” explains the gradu-
ate of both Victoria and Concordia Universities. “They com-
forted me.”
Whatever the reason, over the past 15 years,
sound has brought him into collaborations with musicians
and dance troupes – and into honing the
sounds of the city to produce “soundwalks.”
In the Micro Radio Project he carried out in
Quebec City, Roos created a counterpoint be-
tween resident’s voices, and recordings of
trains and church bells. Thinking back over his initial flir-
tation with silkscreen, in which he would have to push and
pull multiple layers, Roos can see a similarity to using a
multitrack to layer sounds. “Sound is a visual experience
for me,” he concludes.
Back at the art gallery, we’re still enjoying the ebb
and flow of his installation. Ross plans to take the con-
cept even further in future projects. Repurposing more
objects – such as a refrigerator that hums rhythmically in
tandem with a stove, for instance – to explore the tangi-
bility of their “seductive and captivating” low frequen-
cies. “It changes people because all of a sudden they can
actually feel something that they have never heard,” he
says as the sofa’s leather seats rise as if on cue to punc-
tuate our conversation. ■
