1. A method for conducting a cross frequency simultaneous masking (xF SM) test, the method comprising:
generating a signal probe and a masker probe, wherein a center frequency of the signal probe and a center frequency of the masker probe are separated by a first fixed frequency ratio;
for a given frequency range, generating a first xF SM curve by:
sweeping the signal probe and the masker probe across the given frequency range while maintaining the first fixed frequency ratio between the signal probe and the masker probe; and
maintaining the masker probe at a pre-determined masker amplitude;
adjusting the amplitude of the signal probe in response to a series of user inputs;
interpolating the series of user inputs to generate the first xF SM curve.
