Introduction, September, 1968

When I was invited by the regular editor, S. Okwit, to be Guest Editor of the special issue of this TRANSACTIONS on the subject of noise, I had no idea how many man-hours of effort would be involved. My management may or may not have known either, but, nevertheless, they encouraged me to accept the invitation, which I did. I am happy to report that I have had their whole-hearted support not only in providing me with special secretarial assistance, communication conveniences, and incidental expenses, but also in granting me the time to complete the assignment.
