Aug 1980, page 158, sounds like the second article you refer to:
attaching mirrors to two speakers oriented at angles to each other, etc.
(The same issue has an opened disk drive on the cover and an article about
disk drive technology.)
That sounds entirely familiar for the original, but the specific
publication I'm thinking of is a 5mm-thick soft-bound book containing
a dozen articles/projects about lasers - generating coherent light and
using coherent light.
I don't have the publication in front of me or I'd cite chapter and
verse. Thanks for the reference to what was probably the original
article. These days, one could whip up some software for a sound card
to generate the functions, or one could even write a program to make
an audio file, then let an iPod play back the X and the Y waveforms as
left and right channel ;-)
