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. 一种作业车辆，具有底盘和连接到底盘以用于相对于底盘运动的构件。致动器连接到底盘和构件以相对于底盘移动构件。液压回路连接到致动器，并且泵对液压回路中的流体加压。可调节的四分之一波调谐器连接到液压回路。可调节的四分之一波调谐器具有在长度范围内能够调节的长度，从而降低在相应频率范围上由泵引起的噪声。在一些实施例中，所述构件是线性致动器，例如液压缸。在其它实施例中，所述构件是旋转致动器，例如液压马达。
