[NA361-F] N-17-01-06 (1917)

This notebook was used by Absalom M. Kennedy during January-February 1917. The entries consist primarily of daily logs of experimental recording activities at the Columbia Street Studio using various kinds of music and recorders. Included are comments on the loudness and quality of the sound. The determination of quality was based partly on "tone tests" in which a performer's recordings were compared to a live performance by the same individual. The notes indicate that Edison oversaw the work and periodically listened to the experimental recordings and that E. Rowland Dawson and Clarence B. Hayes assisted in some of the experiments. At the beginning of the book are two pages by an unidentified author noting the numbers of blanks on hand. Inserted into the book is a three-page list in Kennedy's hand of projects and instructions, along with a related typewritten list. The front cover is labeled "Notes, Columbia St. Studio from Jan. 6, 1917." The pages are unnumbered. Approximately 40 pages have been used.
