Report of the Sound Committee

As noted in the Spring report, the Sound Committee has addressed itself to four main projects. Upon the first of these, namely, that of establishing Primary and Secondary Frequency Reference Standards, considerable work has been done, principally because the Committee regards this project the most important, and for that reason concentrated its attention upon it. This report, therefore, will be restricted to that phase of the Committee's work.
