Questionnaires were submitted to 200 Air Force base personnel located in executive, engineering, and shop foremen offices. The questionnaires asked for ratings of the noise conditions, effects of noise on telephone usage and conversation, sources of interfering noises, nature of the job and the activity most affected by the noise. Octave band sound levels and time variation patterns were measured over a period of two weeks for correlation with the subjective information. The results are compared to previously published data [Leo Beranek,Acoustics(McGraw‐Hill Book Company, Inc., New York, 1954), pp. 423–425]. [This work was supported by the U. S. Air Force.]
