Special notice: ASA meeting papers

Instructions for the preparation of abstracts for papers to be presented at meetings of the Acoustical Society of America are mailed to all members with meeting announcements. For the benefit of nonmembers who submit ab- stracts and for members who wish to have a permanent reference, instructions and a sample abstract are published below. Adherence to these instructions will be very helpful to meeting chairmen and insure that programs will be mailed well in advance of meetings.

BETTY H. GOODFRIEND

Secretary

Preparation of Abstracts ( 1 ) An abstract in four copies is required for every meeting paper, one of

which should be an original. Send the four copies to the Technical Program Chairman of the meeting, in time to be received by the stated deadline; in the USA allow at least 7 days for delivery. Deadline dates are given in the news section of every issue of the Journal of the Acoustical Society of •4rnerica (JASA). A cover letter is not necessary.

(2) Limit the abstract to 200 words, including title and first author's name and address (names and addresses of coauthors need not be counted). Display formulas--those set apart from the text--are counted as 40 words.

(3) Title of abstract and names and addresses of authors should be set apart from the abstract. Text of abstract should be in one single, indented paragraph. Type double spaced on one sheet of 8« X 11-in. paper.

(4) Be sure that the mailing address in the abstract is complete for the

author to whom the acceptance or rejection notice is to be sent. (5) Do not use footnotes. Use square brackets to cite references or

acknowledgments of financial support. Give references in format required for JASA.

(6) Underline nothing except what you wish to see italicized. (7) If the letter I is used as a symbol in a formula, loop the letter I by

hand and write "lc ell" in the margin of the abstract. Do not intersperse the letter O with numbers, where zero might be understood; but if unavoidable, in the margin write "capital oh." Note phonetic symbols by similar marginal remarks.

(8) At the bottom of an abstract give: (a) The name( s ) of the Technical Committee( s ) most appropriate for the subject matter. See the inside back cover of any recent issue of JASA for list of ASA Technical Committees.

(b) PACS subject classification number(s) under which the ab- stract should be indexed (see subject classification in any recent June or December issue of JASA).

(c) Telephone number of accessible author, including area code. (d) If more than one author, name the one to receive acceptance or rejection notice. (e) Describe on the abstract itself any special equipment needed; a Vu-Graph for transparencies and a projector for 50 X 50-mm slides will be available for all papers and should not be mentioned. (f) If paper is in Psychological and Physiological Acoustics or Speech Communication, indicate a preference, if any, for lecture or poster session for presenting the paper. (g) Indicate the special session (see call for papers) to which paper might be assigned.

(9) IMPORTANT: Give a copy of these instructions to your secretary.

Binaural loudness summation for tones and noise. Albert B. Sea and Irene J. Knox (Dept. of Psychology, Northeastern University, Boston, MA 02115)

The relation between binaural and monaural loudness was measured by magnitude estimation for a 1000- Hz tone and for bandlimited white noise. Four types of stimulimmonaural and binaural tone, monaural and binaural noise•were presented frontally at eight sound pressure levels (SPL) in mixed randomly selected sequences. Subjects were instructed to rate the four stimuli according to a single loudness scale. The loudness of the monaural and binaural tones was found to be a power function of the mean square sound pressure, with an exponent near 0.5. The loudness of the noise increased more rapidly at low SPL than loudness of the tone; at high SPL it increased more slowly. The bow shape of the noise function would be predicted from loudness matches between wideband and narrow-band stimuli. A sound perceived binaurally was 1.3 to 1.7 times louder than sound of the same SPL perceived monaurally. The results of these direct loudness estimations agree almost perfectly with earlier results [ D. E. McGee and I. J. Knox, J. Acoust. Soc. Am. $7, 55-62 ( 1975 ) ] from another group of subjects who made loudness matches between binaural and monaural stimuli. [Work supported by NSF.]
