Earlier than this. The first papers I have are from the 20's.

The articles are fast and thick in the Journal of the Acoustical
Society of America starting in about 1958... many seminal papers
including much of the raw masking data used directly in Vorbis are
from papers of this era. Look at masking.h in the Vorbis source, as
well as searching the old vorbis/vorbis-dev mailing list archives for
numerous references.
