Abstract
A hearing aid with different assemblies for picking up, further processing and adjusting an acoustic signal to the hearing ability of a hearing impaired person, wherein a digital signal processing is performed in the hearing aid, has a buffer storage unit which shifts or transposes a defined frequency region into another frequency region which is better detectable by the wearer of the hearing aid. The buffer storage unit has individual storage segments for receiving and storing digital data representing acoustic content of an incoming audio signal, and the read-in and read-out frequency of the buffer storage unit differs by a defined factor.
