Ian Betty first heard the loud low-frequency sound in 2011. It permeated the air
and even drowned out noise from Highway 417, which sits close to his Robinson

three rooftop chiller units that had been installed that year on top of a
Canadian Police Information Centre building on Vanier Parkway across the river
from their homes. via
