Fabrication of a new headset for air- and bone-conduction audiometry

The construction of a new audiometric headset which supports both ac and bc transducers is described. The bc transducer can be adjusted from 0-1500 g force. Future development should be directed toward (1) determining if such a headset is adjustable and stable on different size heads, (2) determining the test-retest reliability of the force measuring system, (3) reshaping the headset to make it smaller and more comfortable, and (4) consolidating the power/amplifier supply into a single unit.
