General Considerations

Many otologists and audiologists, while having considerable confidence in methods of testing hearing by air conduction, have little confidence in bone-conduction tests carried out in the time-honored fashion with a bone-conduction receiver applied first to one and then to the other mastoid process. Many believe that bone-conduction testing has some value as a supplement to the classical tuning-fork tests, but that it lacks any useful degree of precision and must be allowed to serve only as an approximate guide to the nature, rather than an accurate measure, of a hearing impairment. One reason for this belief may be the observation that bone-conduction test results are evidently more readily influenced by a number of variable and extraneous factors than are air-conduction tests of hearing requiring the use of a pair of air-conduction receivers. The efficiency of bone-conduction hearing is, for example, influenced to a considerable degree by the position . . . [Full Text PDF of this Article]
