I got an electric leaf blower mostly to avoid the noise and partly to avoid gasoline engine issues (a Kobalt 80V blower). What baffles me is that here the designers had a chance to make something truly quiet but instead they blew it and used a super-high-RPM motor-powered narrow turbine placed inside the pipe. It sounds like a dental drill amplified through a set of loudspeakers.
I would kill to get a commercially designed blower powered with a large squirrel cage driven by a low-RPM brushless motor. I'm sure they exist by now and I imagine they are glorious. I'm not sure what these students did but if I was doing that project today that is the first thing I would try.
