Hi Dick :)

According to http://permalink.obvsg.at/AC02877741 the external archive
of the Innsbruck Library (UBI-HB.BL) should have it which happens to
be across the street of MED-EL :) so I'll try to get the two papers
tomorrow during the lunch break.

 And if nobody has it, maybe someone will help me figure out how to get a
copy from one of the libraries that has the Arch. f. d. Psych.:

http://www.worldcat.org/title/archiv-fur-die-gesamte-psychologie-organ-d-deutschen-gesellschaft-fur-psychologie/oclc/231008568

Lots in Germany, a few in France, and one in Zurich.  Any volunteers?

I also found a commentary that said the time-difference that Klemm found was
1/100 $\sigma$; some looking around informed me that $\sigma$ was an old
abbreviation for a millisecond, so this is 10 microseconds.  Seems a lot
more reasonable than the 2 microseconds that another book talked about.  I'd
like to see what else he said (I think I can make out German almost well
enough to get the gist of it).

As far as I can tell, this may be the first guy to investigate inter-aural
time difference of clicks and complex sounds (as opposed to just inter-aural
phase difference of sinusoids).

Otto Klemm apparently did great work on binaural localization, including
time-intensity trading. But I can't find a clear statement of how small a
time difference he found to be detectable. One paper says 2 microseconds,
but I suspect that's wrong.

I have his 1913 and 1914 papers (freely available online), but can't find
these more important later ones:

Klemm, Otto (1918). Untersuchungen uber die Lokalisation von Schallreizen.
3. Mitteilung: Uber der Anteil des beidohrigen horens. Archiv für die
gesamte Psychologie, 38, 71-114.

Klemm, Otto (1920). Untersuchungen über die Lokalisation von Schallreizen.
4. Mitteilung: Über den Einfluß des binauralen Zeitunterschiedes auf die
Lokalisation. Archiv für die gesamte Psychologie, Bd. 40, 117­146.

Does anyone have or know where to find them?
