... VIII. RESEARCH PERSONNEL AND RESEARCH PROVISIONS It is apparent to the Conference that personnel adequate to the undertaking of the galaxy of investigations which have been outlined under headings I to VI is not now available, and that the development of investigators competent to conduct many of the details will require time, and will depend upon efforts intelligently directed toward such development.

... That steps be taken to acquaint various scientific departments throughout the United States and Canada with the research program herein presented, with the need of drawing highly capable persons into this work, and with the existence of problems supplementary to this program which may well receive the attention of graduate students planning doctoral research.

... Instruments for measuring auditory capacity and deficiency have long been known by the standardized name of acoumeters. The hybrid term " audiometer " has also been applied to a number of instruments of the same types to which the name acoumeter is applied, but in the United States at present is generally tolled as referring to the improved acoumeters developed in the Bell Telephone Laboratories.

... b. In attempting to ascertain correlations of auditory deficiency with possible causative and influencing factors, certain specific objectives suggest themselves, viz: The past incidence or present existence of those diseases and defects which might be suspected of significance; history of accidents.

... As an alternative it is suggested that the following method be used: The hearing of the subject by air conduction should be measured at a low frequency, an intermediate frequency, and a high frequency. A person who could hear a standard intensity at each of these points would be passed as of " normal " hearing.

... e., limited by selection as to sex, age, race or nativity, and intelligence, it is assumed that to ascertain the magnitude of the problem is a major objective, and that actual conditions in a considerable sample of the population should be observed. At the same time, it appears feasible to extend the inquiry, in certain of its phases, to a considerable sample or series of samples, and to restrict the study of other phases to smaller groups.
