We present experimental results obtained in a turbulent boundary layer at a Mach number of 2.3 impinged by an oblique shock wave. Strong unsteadinesses are developed in the interaction, involving several frequency ranges which can extend over two orders of magnitude. In this paper, attention is focused on the links between the low frequencies shock motions and the separation bubble. An interpretation based on a simple scheme of the longitudinal evolution of the instantaneous pressure is proposed. As it is mainly based on the pressure signals properties inside the region of the shock oscillation, it may be expected that it will be still relevant for different configurations of shock induced separation as compression ramp, blunt bodies or over expanded nozzles.
