Abstract: An assisting listening device having audiometry function includes an earphone, a testing signal generator, a feedback generator and a control box. The testing signal generator is controlled by a digital signal processor of the control box to provide a testing signal to a speaker of the earphone. The feedback generator will generate a feedback signal to the digital signal processor of the control box subject to the testing signal, enabling the digital signal processor to evaluate the user's hearing threshold level so that the user can adjust the functioning of the assisting listening device optimally subject to the evaluation result.

Abstract: An audio signal processing system for use in assisting listening devices is disposed in a digital signal processor. The audio signal processing system comprises an input signal conversion unit, a signal compression unit, a hearing curve adjusting unit and an output signal conversion unit. An external audio signal can be converted from an analog format into a digital format by the input signal conversion unit, it is then compressed by the signal compression unit to be output to the hearing curve adjusting unit for adjusting parameters of the audio signal based on a hearing curve preset value, then it is output to the output signal conversion unit for the hearing signal to be amplified and converted from the digital format into the analog format for output, the audio signal is finally converted into music or voice by speakers of an assisting listening device to be output into a user's ears.
