1. An apparatus for assisting a patient in loosening and/or clearing fluids, phlegm and mucus collected in a patient's sinuses, lungs, bronchial and/or tracheal passages comprising: an elongated curved hollow housing having a substantially closed end portion and an open end portion, the open end portion forming at least part of an acoustic coupling chamber; a generally funnel shaped tapered mouthpiece having a large end adapted to fit onto the open end portion of the housing, tapering to a small end portion sized to be inserted into a patient's airways, the mouthpiece forming another part of the acoustic coupling chamber, wherein the mouthpiece includes at least two baffle shelves formed therein transverse to a central axis through the mouthpiece, at least one baffle shelf having a central notch therein; and an acoustic signal generator housed within said hollow housing having an acoustic transducer directing acoustic vibrations into and through the coupling chamber into at least one of a patient's airways when the mouthpiece is coupled into the at least one of the patient's airways, and wherein the baffle shelf deters fluid, phlegm, and mucus expelled from the patient's airways from collecting on the acoustic transducer.
