Abstract
A hearing aid includes: a microphone configured to provide a microphone signal that corresponds with an acoustic stimulus naturally received by a user of the hearing aid; a processing unit coupled to the microphone, the processing unit configured to provide a processed signal based at least on the microphone signal; a speaker coupled to the processing unit, the speaker configured to provide an acoustic signal based on the processed signal; and a sensor configured to measure a neural response of the user to the acoustic stimulus, and to provide a sensor output; wherein the processing unit is configured to detect presence of speech based on the microphone signal, and to process the sensor output and the microphone signal to estimate speech intelligibility; and wherein the processing unit is also configured to adjust a sound processing parameter for the hearing aid based at least on the estimated speech intelligibility.
