Abstract:
A hearing aid comprising:an input transducer, which receives an input signal, and an output transducer, said input transducer and said output transducer having a signal path therebetween traversed by said input signal;amplifier and transmission means connected in said signal path for modifying said input signal, said amplifier and transmission means containing at least one adjustable circuit component which acts on said input signal, and said amplifier and transmission means having a signal tap at which a tapped signal is present;completely digitally constructed calculating means, disposed outside of said signal path and connected to said signal tap, for generating a control signal dependent on said tapped signal by applying said tapped signal to a neural structure in said calculating means outside of said signal path, and for supplying said control signal to said at least one component in said amplifier and transmission means for modifying said input signal in said input path dependent on said tapped signal; andan analog-to-digital converter connected between said amplifier and transmission means for converting said tapped signal into a digital signal, and a digital-to-analog converter connected between said calculating means and said amplifier and transmission means for converting said control signal into an analog signal.
