Laboratoire de Physique Appliquée du Muséum, 43 rue Cuvier, 75005 Paris, France A dynamic study demonstrates and evaluates the transitory lack of performance at a tunnel entrance evidenced by a sharp increase followed by an asymptotic decrease with time of relative threshold. This overshoot is characterised by its amplitude and its position in time with respect to tunnel entry.
