Shlomo Dubnov is at UCSD, you could ask him if he has a copy http://musicweb.ucsd.edu/~sdubnov/
Dubnov's paper is online at http://musicweb.ucsd.edu/~sdubnov/Papers/dubnov95hearing.pdf and the reference is to Gerzon's bispectral models, which are covered in "General Metatheory..." (92nd AES Convention, Vienna, 1992, Preprint 3306).
