In a method and hearing aid (200) for processing sound signals for hearing impaired persons by providing multi-band compression processing an input sound signal is filtered by a band split filter (202) into a number of frequency bands to obtain band split signals. A signal level for each of the band split signals is determined and the frequency bands are arranged into a number of groups. Based on the signal levels in each of the groups, a compressor input level for a number of band split compressors each associated to one of the frequency bands is calculated. A compressor gain for each band split compressor is determined based on the corresponding compressor input signal and the band split signals are amplified with the corresponding compressor gain and summed in a summing unit (208) to produce an output sound signal.

A DC voltage value from a DC voltage detection unit (201) is directly inputted to a voltage correction unit (202) without using a compensator or a filter. Accordingly, a voltage correction unit (202) can rapidly perform a correction process even upon a sudden voltage change such as an instantaneous power supply stop, an instantaneous voltage lowering, or a recovery from an instantaneous voltage lowering. Moreover, since a limit unit (212) limits a link resonance compensation amount to a predetermined range, it is possible to prevent an excessive fluctuation of a link resonance compensation amount upon a sudden voltage change. Moreover, the link resonance compensation amount limited to the predetermined range by the limit unit (212) is inputted to a compensator (206) of an appropriate control band in control calculation units (204 - 208). Accordingly, it is possible to avoid response of a higher speed than is necessary and perform stable control.
