Today’s invention is a silencer for that neighbourhood dog whose owner is unable to stop it barking all the time.
Since each dog has a pretty characteristic and consistent nuisance-bark wavelength, this would take the form of a simple muffler device with a resonator chamber which would be adjustable in length to allow cancellation of that particular animal’s bark.
At night, the dog would wear a muzzle fitted with a silencer of this type made of lightweight plastic material.
