Apparently. According to Benade:
"When a nonlinear system is subjected to sinusoidal forces,
heterodyne components are generated. ... The frequency relations of
these heterodyne components are always those described in the schema
given earlier, *regardless of the nature of the nonlinearity*
(neurological or mechanical)."
"The amplitudes of the heterodyne components generated by a nonlinear
system depend on the details of the nonlinearity and (in general) on
the amplitudes of the excitatory forces." (Benade, "Fundamentals of
Musical Acoustics", 2nd Ed. at pp. 262-63, emphasis in original).
