A work vehicle has a chassis, and a member connected to the chassis for movement with respect to the chassis. An actuator is connected to the chassis and to the member to move the member with respect to the chassis. A hydraulic circuit is connected to the actuator and a pump pressurizes fluid in the hydraulic circuit. An adjustable quarter wave tuner is connected to the hydraulic circuit. The adjustable quarter wave tuner has a length that is adjustable within a range of lengths to thereby reduce noise caused by the pump across a corresponding range of frequencies. In some embodiments, the member is a linear actuator, such as a hydraulic cylinder. In other embodiments, the member is a rotary actuator, such as a hydraulic motor.
