Classification: CPC H  G | IPC G  H

Claim 2:
3. The system for automatic detection of music listening reactions of claim 1, wherein the filter unit:
determines as a vocal non-reaction event, a data segment in which a movement level of the listener in the inertial signal is lower than a first movement threshold,
determines as the vocal non-reaction event, a data segment in which the listener's movement level in the inertial signal is higher than a second movement threshold, and
determines as the vocal non-reaction event, a data segment in which a volume of the sound in the sound signal is lower than a sound threshold;
determines as a motion non-reaction event, a data segment in which the listener's movement level in the inertial signal is lower than a third movement threshold, and
determines as the motion non-reaction event, a data segment in which the listener's movement level in the inertial signal is higher than a fourth movement threshold;
wherein filtering of the inertial signal is performed prior to filtering of the sound signal.
