Designed for activating tuning forks with greater precision, the apparatus here presented (see photograph) has been useful in two different ways: (1) to demonstrate that such a device is not needed, and (2) to explain why it is not needed. In other words, by the use of the apparatus it was discovered that strong blows (not weak blows) delivered in any manner desired always gave uniform results. Later it was thought that it might be of interest to present that fact and also, by means of the new knowledge in physics and the physiology of hearing, to explain the findings. This leads to emphasis on the importance of standardized tuning forks and a sound-proof room, rather than on devices for exciting tuning forks.

In times past many devices have been described and suggestions offered for activating tuning forks with a standard blow for functional hearing tests. On the same subject . . . [Full Text PDF of this Article]
