ABSTRACT:
A device and method for fitting a sound transmission device to provide an easy and effective fit, reduce feedback, and improve user comfort comprises an ear-piece component having a face at one end with operative components and a stem adjacent the other end. The stem houses a speaker tube which protrudes from the component, and it has a retaining means for securing an inflatable, resilient fitting balloon thereon. The balloon has a sound transmission duct within it which can be coupled to the speaker tube so that when the balloon is secured to the stem, a continuous path is provided for the transmission of sound from the component to the user's ear canal external the balloon. This assembly (e.g., the component and attached balloon) is inserted into the ear canal when the balloon is in a deflated configuration. Air is then pumped into the balloon, e.g., through an air channel in the ear-piece component, to inflate the fitting balloon. The inflated fitting balloon engages the ear-piece component against the walls of the user's ear canal and prevents sound from traveling to the external ear and face of the component.
