The report contains a summary of the work performed for the design and construction of a lightweight and miniature type handset, hand-held microphone, double earphone headset and telegraph key. The report contains a review of the work performed in this period which consisted of designing an acceptable configuration of these items and a satisfactory and acceptable electroacoustical design of the earphone and microphone elements. From the preliminary design, configuration, it appears that the design goal of reducing the weight of each item by 50 percent will be readily achieved. Also, these configurations will conform to good human engineering design standards. Author
