Abstract :
PREPARED under the auspices of the subcommittee on sound∗ of the AIEE standards committee, this preliminary report is intended to provide some basis for standardized technique in the relatively new field of apparatus noise measurement. Because of the newness of apparatus noise investigations, and the importance of the subject, the subcommittee anticipates some possible inadequacies in this report, and solicits criticisms and comments from readers. To facilitate specific discussions, paragraphs are numbered.
