摘要： Apparatus for and method of correcting multiple distortions in the form of amplitude variations in and extending the output response of acoustic devices are disclosed. In one embodiment, a set of one or more hollow pipes or conduits of predetermined sizes is positioned adjacent to an acoustical source and oriented such that the axis of each pipe is at an angle to the axis of the sound and at least one open end of each of the pipes intercepts the sound as it is propagated. In an alternative embodiment, comparable results are achieved by positioning a slotted bridge, with one or more elongated slots of predetermined size, adjacent to an acoustical source such that the axis of each slot is oriented substantially perpendicular to the axis of the sound and the sound wave intercepts the open edge of each of the slots.
