Growth of the Acoustical Society of America


The plot on the left indicates the annual growth of the following:

Total membership of the Society in all categories, as reported in the spring of each year, usually in the April issue of JASA. There are now six categories of membership: Honorary Fellow, Fellow, Full Member, Associate Member, Student Member, and Emeritus Member.

Number of Fellows, as reported in the spring of each year.

Total number of pages published each year in the Journal (JASA). This total (since 1990) includes all text pages and indexes in regular issues and supplements, References to Contemporary Papers in Acoustics, and abstracts of papers in meeting programs, but excludes advertisements and other "front" material. Note that the size of journal pages increased in 1974 from 7 7/8 x 10 1/2 to 8 1/4 x 11 1/4 inches. This increase resulted in an estimated increase of about 7 % in the number of text characters per page.

The registration per regular meeting of the Society. This is a 4-meeting average obtained each year by combining the registration at the meetings held within the year with that at the fall meeting of the previous year and the spring meeting of the subsequent year, except that the ICA meeting in 1956 has been omitted.

The number of paper abstracts submitted per meeting. This is also a 4-meeting average calculated as for the registration per meeting number.
