SUZUKI AND ICHIKAWA state that so-call ed occluded Lone conduction test, which is per-formed by occluding the external meatus, has been employed merely, for differentiation of the nature of deafness with which the ear may be involved. But, this test may be employed for o btaining results the amount of hearing loss by conduction, if thresholds of hearing of the norm-al and the involved ears are first acqui.red; the difference in these two amounts can be regarded as the actual value of hearing loss found in the involyed ear. Furthermore, the method requires no sound-proof room nor is there a fear of inte-rference by sounds caused by air conduction in its performance.
