THE ASCENDANCY of the acoustic physicists in the literature on the functional tests of hearing continues. We have tried to fit their ideas into office procedures within the facilities of the practicing otologist so far as we could.The problem of shortened bone conduction and its relation to the indications for fenestration seems difficult, as it can occur even in tubal cases, for instance, if the round window is obstructed by secretion or the like.
Guilford and Haug1 discuss the problem of the otologist and the hearing aid. The ideal candidate for a hearing aid is one with an average loss of 30 db. or more in the better ear, absence of recruitment and tolerance problems for amplification, and a noninfected external canal, middle ear, or mastoid process. He should have satisfactory discrimination ability and be psychologically prepared to adjust to the associated early noise discomfort
