<P>PROBLEM TO BE SOLVED: To improve stability of a hearing aid and to make it easier to hear a high-frequency sound. <P>SOLUTION: The present invention relates to the hearing aid and a method for correlative removal of an input signal 6 and an output signal 12 of the hearing aid 2. The hearing aid includes a high-pass filter 14 and a low-pass filter 16 which divide the input signal 6 into a high-frequency part and a low-frequency part 22, a composing unit 18 which generates a composite signal 24 based upon the high-frequency part of the input signal 6 and a model, and a combining unit 20 which combines the composite signal 24 with the low-frequency part 22 of the input signal 6. The model is based upon a period function. The phase of the composite signal 24 is randomized at least partially. <P>COPYRIGHT: (C)2012,JPO&INPIT |
