Abstract
An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to present a spectro-temporally modulated audio signal to a user. The spectro-temporally modulated audio signal may be modulated within both a frequency domain and a time domain. The processor may be further configured to execute the instructions to adjust a modulation depth of the spectro-temporally modulated audio signal while the spectro-temporally modulated audio signal is being presented to the user, determine, during the adjusting of the modulation depth, a modulation detection threshold that corresponds to a minimum modulation depth at which the user is able to perceive modulation of the spectro-temporally modulated audio signal, and determine, based on the modulation detection threshold, a hearing capability of the user.
