Yes indeed landscaping power tools need innovation to quiet them down! I am also tired of hearing it from inside my home.
However, noise on the AC line is a different sort of noise that aggravates me and others. This noise is not like trace DC levels causing tranny buzzing etc… No, rather this is the type of junk on the AC line that robs music of its realism. Junk that interferes with realism, not noise that you hear through a driver.
Yes, all this noise and junk is real. Both yard care and riding in on our AC lines.
