Abstract: The invention relates to an information distribution system, especially to an audio information distribution system including one or more local systems, each being intended for personal use or for the use of a small group. In order for the system to be adapted as well as possible to the current state of the user, the user is connected as a part of the system so that his or her current state affects the way information is supplied to him/her. Thus, the user is part of the system and part of the control circuit which affects the information flow. The state of the user is evaluated by measuring at least one somatic phenomenon from him/her, and the content of the information and/or presentation parameters are changed on the basis of the measurements.
