The present study investigates the acoustic characteristics of leading edge (LE) and trailing edge (TE) modified airfoils, which is compared with baseline un-serrated airfoil. The acoustic characteristics are investigated through an acoustic camera. The study shows uniform acoustic radiation throughout the span of the baseline airfoil, while the dominant radiation is seen from the root and tip sources of the LE/TE modified airfoils. Further, the flow visualization was done on baseline and LE/TE modified airfoils to understand the flow behavior and its connection with the acoustic radiation. It shows uniform flow over the span of the baseline airfoil, which indicates uniform acoustic radiation. The flow is not uniform throughout the span of the LE/TE modified airfoils which represents lower acoustic radiation. It can be concluded that the LE/TE modified airfoil could inhibit the spanwise growth of the vortices and reduces the radiation intensity.
