  • Removable tip for an acoustic reflectometer
    Patent number: 6053875
    Abstract: In one embodiment of the invention, the tip has a conical portion. Four connection tabs are orthogonally and evenly spaced on the outer circumference of the conical portion. The tip has a flange surrounding an outer circumference of the conical portion and parallel to the connection tabs. Between the connection tabs and the flange is a gap. The connection tabs and gap have a size such that they securely connect the tip of the acoustic reflectometer. The tip also may have a set of handling tabs connected between the flange and the conical section which simplify attachment of the tip to and removal of the tip from the acoustic reflectometer. The inner diameter of the tip has a shape that provides a matching acoustic impedance to the ear canal.
