This paper discusses the near- and far-field of leading- and trailing-edge noise generated by a NACA0008. Wall-pressure fluctuations are the highest close to the leading edge, suggesting that the leading-edge noise is the dominant noise source for turbulent inflows. This is confirmed by far-field noise measurements. Trailing-edge noise is comparable to the leading-edge noise for high frequencies.
