Disclosed is a device for hearing tests and auditory assessments, including: an all-digital audio and tone signal synthesis generator for converting a logic algorithm and a parameter into a digital signal via built-in software, and inputting the digital signal into a digital signal processor (DSP) or processing the same with a PC central processor (CPU) to generate and output a multi-modal audio and tone acoustic signal; a hearing test module, comprising one or more objective and/or subjective hearing test submodules, sharing corresponding stimulation or interference signals converted by signals input by the same all-digital audio and tone signal synthesis generator, in order to perform a hearing test on a patient; and a comprehensive auditory assessment module for performing comprehensive auditory assessment on the hearing test result output by each hearing test submodule.
