Progress in noise measurement standards

Efforts to develop standards for noise measurements were actively initiated during the Institute´s North Eastern District meeting held in Rochester, N. Y., April 29–May 2, 1931. As one of the steps in the program to develop standards, a session on sound measurement was held at the recent winter convention, New York, N. Y., January 23–27, 1933. At this session an address was delivered by Dr. Harvey Fletcher (M´23, F´30) of the Bell Telephone Laboratories, Inc. Following this address a meeting of the A.I.E.E. committee on sound was held, as reported elsewhere in this issue. Suggestions from members in connection with the subject of sound measurement will be welcomed by the committee.
