Windsurfers often pump their sails back and forth to gain speed, but it can also cause slowing if done incorrectly. The complicated physics of the action was tackled by our group. Recently, the research group examined the propulsive dynamics of sail pumping on sailboards and established two quantities that measure the…

The in-house ENVironmental Acoustic Ray-tracing Code (EnvARC) at the AANTC generates acoustic maps using generalized acoustic sources, generic terrain and building models with user-defined impedances, and resolves the effects of atmospheric sound absorption and refraction. The inputs consist of the noise source and en…
