Dear Noam,

I do not have the reference, but you might be interested in a 'modern'
version (http://web12.v1357.ncsrv.de/index.php?show=10), which is on
display at our 'hearing garden' (http://www.hoergarten.de/, in German).
As a part of their practical training, our students measure several
properties like amplification or improvement in the
minimum-audible-angle (unpublished data).

Best regards,

Volker Hohmann
