The invention relates to an implantable device, e.g. a Deep Brain Stimulation device (10), and to a method for communicating information from such an implantable device (10) to its carrier. The communication is achieved by the emission of sound from a transmitter (16) into the body material surrounding the implantable device (10), wherein said sound yields signals that are audible for the carrier of the implantable device (10). In particular, the emitted sound may comprise audible frequencies or modulated ultrasonic frequencies. According to a further development, the implantable device (10) may additionally comprise a receiver (16) for receiving sound from the surrounding body material, wherein said received sound may encode information for the implantable device (10).
