»earis«® opens up a completely new dimension for hearing impaired people to listen to and enjoy feature films, speech and music programmes on TV, Radio or from any other audio device. The integrated Dynamic Sound Hearing Support (Dynamic sound HS) offers five selectable basic tone profiles. These five basic tone profiles were derived from research on the needs of hearing-impaired people when listening to the types of programmes described above. This research was carried out by the Fraunhofer Institute for Digital Media Technology IDMT in Oldenburg, Germany. Whilst listening with the selected (preferred) tone profile the listened to programme is then continuously and dynamically being altered, by implementing an algorithm developed by the Fraunhofer Institute. This for example keeps any loud sounds from reaching the users hearing. This „cushions“ the naturally chang- ing levels for the respective listeners when advertisements are displayed or when switching to another TV channel. It acts like a continuously varying tone control on the listened to sound to match it to the users selected tone profile. A large volume wheel is used for overall volume control up to 122 dB (A
