The smallest in-the-ear hearing systems from Audio Service are called Icon. These extremely small devices are available as either DIC (from TL 8 upwards) or mini-CIC systems. A DIC has inserted so deeply in the auditory canal that it sits directly next to the eardrum and is therefore not externally visible. It functions completely automatically, i.e. the hearing system automatically adjusts to different hearing situations. The fact that it sits so deep in the ear offers not only cosmetic but also auditory advantages, as your hearing system specialist will be happy to explain to you. The mini-CIC version of the Icon is also practically invisible because it sits deep in the anterior auditory canal. This version offers the option of manual operation by a push button which enables the user to switch between multiple hearing programs. The choice of version depends on anatomical factors and your personal requirements.
Icon hearing systems are available from tech level 4 upwards.
