Abstract
In a hearing aid having a microphone and an earphone with a signal processing unit connected therebetween, and a method for operating such a hearing aid, a filter element in the signal processing unit splits the signal from the microphone into a number of partial signals, and each of the partial signals is analyzed, to determine whether they respectively contain speech information, by comparing the magnitude of the envelope of the partial signal to the average value of the partial signal. For any partial signal having an envelope magnitude which exceeds the average value, the analysis unit operates an amplification stage to amplify that partial signal before it proceeds to the earphone.
