Abstract: 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.

Abstract: The present disclosure discloses a music earphone, which comprises an auricle-shaped shell, a cover, and a cavity formed by the auricle-shaped shell and the cover. A receiver(s) is disposed in the cavity, a sound aperture is disposed at an upper end of the shell, an edge of the sound aperture extends towards the interior of the cavity to form a cylindrical hearing tube, a lower end of the hearing tube is fixedly connected with the receiver(s), and a lower end of each of the receiver(s) is connected with a conductor. The music earphone allows the shell to match the auricle of a user in a breathable manner, filter out the external noise while still enabling the user to hear the external communication sound, improve the music quality, and guard the traffic safety of the user.
