In this paper, radiated sound from low Mach number turbulent boundary layers is studied using Lighthill's analogy. The focus is on investigating the behavior of wall pressure fluctuations on a flexible wall boundary. Comparisons are made between the results from rigid and flexible walls. At low frequencies, the flexible wall results have shown much higher levels of power spectra. At high frequencies, the spectra of the flexible wall sound radiation merge with those of the rigid wall sound
