%X Organized wave disturbances were artificially introduced in log law region of turbulent boundary layers, and were found damping when propagated downstream, the damping ratios measured were qualitatively in good agreement with the results of Landahl (1967) 5] . As the disturbance wave evolved downstream, its harmonics appeared and the average bursting periods of inner layer decreased because of the outer region disturbances.Organized wave disturbances were artificially introduced in log law region of turbulent boundary layers, and were found damping when propagated downstream, the damping ratios measured were qualitatively in good agreement with the results of Landahl (1967) 5] .
