A method for improving speech intelligibility with a hearing aid device, as well as hearing aid

It is the understanding of speech can be improved with hearing loss in which certain frequency ranges can no longer be perceived even at a high gain. For this purpose a hearing aid (1) with at least one input transducer (3, 4) for receiving an input signal and converting it into an electrical input signal, a signal processing unit (5) for processing and frequency-dependent amplification of the electrical input signal and for generating an electrical output signal and an output transducer ( 6) have been proposed for converting the electrical output signal into a perceptible by a user as an acoustic output signal of output signal a sound detector means (KD) for the detection of sounds in one (in the hearing aid 1) incoming speech signal, a lookup table (LT ), is stored in the (at certain sounds, respectively, a certain output code AK), and a coding device (KE), given by the (in the electrical input signal ES) sounds in the resulting electrical output signal AS) (in each case by the associated output code (AK ) are replaced, comprising. The invention has the advantage that - unlike an ordinary frequency compression - the clarity of speech is not affected to the same extent.
