The practical advantages of a graphic record of air-conducted sound tests of hearing acuity will at once be obvious to the otologist. Herewith are presented a method and chart for this purpose. The actual testing and charting are so simple that it requires but a few moments to train a nurse or clerk for the procedure. A little experience with the method will permit the observer to glean from a glance at the graph a close approximate of the hearing acuity recorded.
The advantages over the audiometer test are: absence of an admixture of bone conduction, portability and inexpensiveness. The audiometer, of course, has the scientific superiority of a wider and continuous range.
1. The greatest sound intensity of a vibrating tuning fork occurs synchronously with the striking of the fork.
2. The more forcible the striking of the fork, the longer will be the period
