PROBLEM TO BE SOLVED: To provide a double-ear hearing-aid system that compensates for a conversation comprehension loss under noise.SOLUTION: A double-ear hearing-aid system 10 comprises: microphones 14, 16, 14B and 16B for providing microphone audio signals 18, 20, 18B and 20B by responding to the sound; a signal separator 12 for providing estimates of an object signal 26 and a noise signal 30 on the basis of the microphone audio signals; a phase shift circuit for shifting a phase of one of estimates of the object signal and the noise signal; a phase shift adder 50 for substituting one of the original object signal and the noise signal by phase-shifting the estimate of one of the object signal and the noise signal; a first receiver 48 for converting a receiver input signal into an acoustic signal that is transmitted toward one eardrum of a user of the double-ear hearing-aid system 10; and a second receiver 48B for converting the receiver input signal to an acoustic signal that is transmitted to the other eardrum of the user.
