A hearing aid (22) having a microphone (1), a processor (53) and an output transducer (12), is adapted for obtaining an estimate of a sound environment, determining an estimate of the speech intelligibility according to the sound environment estimate, and for adapting the transfer function of the hearing aid processor in order to enhance the speech intelligibility estimate. The method according to the invention achieves an adaptation of the processor transfer function suitable for optimizing the speech intelligibility in a particular sound environment. Means for obtaining the sound environment estimate and for determining the speech intelligibility estimate may be incorporated in the hearing aid processor, or they may be wholly or partially implemented in an external processing means (56), adapted for communicating data to the hearing aid processor via an appropriate link.
A method of processing a signal in a hearing aid processor, comprising
A hearing aid comprising an input transducer, a processor, and an acoustic output transducer, said processor having a filter block, a sound environment estimator, a multiplication means, a speech optimization block, and a block overlap means,
A method of processing a signal in a hearing aid, the hearing aid having a microphone, a processor and an output transducer, comprising obtaining an estimate of a sound environment, determining an estimate of the speech intelligibility according to the sound environment estimate and to the transfer function of the hearing aid processor, and adapting the transfer function in order to enhance the speech intelligibility estimate.
A hearing aid comprising an input transducer, a processor, and an acoustic output transducer, said hearing aid including means for calculating a speech intelligibility estimate as a function of at least one among a number of speech levels, at least one among a number of noise levels and a hearing loss vector in a number of individual frequency bands.
