A simple method of expressing the logarithmic measure of physical quantities is proposed, which is generally applicable to all quantities and avoids the use and misuse of the term decibel.Editor's note.—It is believed that discussion and critical thought on this subject should be encouraged. and it is to this end that this Letter is published. The Editors do not necessarily concur with the views expressed.The definition of the decibel and related units will be studied during the forthcoming revision of American Standard Acoustical Terminology Z24.1‐1951 by Sectional Committee Z24. Suggestions (especially in the form of preferred wordings of definitions) are welcomed; address proposals to Chairman of Writing Group Z24.W‐5, Robert W. Young.
