Is 'Investigation of the' necessary in the title? Often titles omit wording such as that since it's understood.]main focus of this paper is on investigating the noise produced by an aerofoilairfoil at high angles of attack over a range of Reynolds number[AU: Journal style does not use italics/math mode for Re. Please check for consistency.]Re ≈ 2 × 10 5 -4 × 10 5 .[AU: Journalstyle uses multdots only in vector math; they have been changed to multcrosses. Please check for consistency.]The objective is not modellingmodeling this source of noise but rather understanding the mechanisms of generation for surface pressure fluctuations, due to a separated boundary layer, that are then scattered by the trailing edge. To this aim, we use simultaneous noise and surface pressure measurement in addition to velocimetric measurements by means of hot wire anemometry and time-resolved particle image velocimetry. Three possible mechanisms for the so-called "separation-stall noise" have been identified in addition to a clear link between far fieldfar-field noise, surface pressure, and velocity fields in the noise generation. * G.Lacagnina@soton.ac.uk
