Twenty years of physics: Acoustics

THE SCIENCE OF ACOUSTICS touches on practically every aspect of human experience; hence it advances on broad fronts ranging all the way from basic physics and chemistry through most branches of engineering to the life sciences. The extent of its development during the past two decades may in some measure be gauged by the growth in membership of the Acoustical Society of America from 1300 in 1947 to 4150 in 1967. During the same period the number of pages published per year in the Society’s Journal grew from less than 1000 in 1947 to 4150 in 1967. This is typical of the world progress in acoustics.
