Abstract
A device for canceling acoustic noise generated includes, in one example, an inlet channel configured to be fluidly connected to an inlet port of a pump and an outlet channel configured to be fluidly connected to an outlet port of the pump. The device also includes an inlet resonator and an outlet resonator, both having open ends and closed ends. The open ends of the inlet and outlet resonators are fluidly connected to the inlet and outlet channels, respectively. When in operation, the inlet and outlet resonators can cancel noise generated by the operation of the pump.
