Abstract
A mounting apparatus for mounting a microphonic probe tube on a patient includes a headband adapted to fit securely on the head of a patient and an adjusting arm which extends outwardly from the headband above each ear of the patient. Each adjusting arm is mounted to the headband in a manner which allows lateral adjustment of the position of the arm so that it can be located directly over the ear canal. The microphonic probe tube is mounted to a mounting rod extending downwardly from the adjusting arm and can be positioned at a point directly outwardly from the ear canal. When the probe tube is so positioned, a dial at the end of the adjusting arm can be turned by the operator to move the probe tube tip a selected distance into the ear canal of the patient to a position at which the real ear measurements are to be made. The precise position of the probe tube tip within the ear canal can be determined by reading the position of an indicator on the adjusting arm with respect to a scale formed along the arm which shows the relative position of the pendant mounting rod and thus the probe tube tip. The secure mounting of the adjusting arm to the headband and the firm mounting of the headband on the head of the patient allows precision measurements of the probe tube tip position to be made and inadvertent contact of the probe tube with the ear drum to be minimized despite motions of the patient's head.
