What makes a good sound? How can speech intelligibility be evaluated? The technical transmission of acoustic signals such as speech is often superimposed by background noises and reverberation, for example at station announcements, mobile phones or in the car. Individual pre-sets and simple intelligent setting options are particularly important because everyone hears differently and well. We offer an improvement in speech intelligibility and sound comfort, taking into account the individual preferences and needs of the user.
