This paper is a summary account of empirical models of the turbulent boundary layer wall‐pressure spectrum and radiated sound. Terminology, definitions, and formulas are reviewed to enable the reader to gain access to the current literature. Empirical representations are given for the wall‐pressure wave number‐frequency spectrum and the acoustic pressure frequency spectrum for both smooth and rough walls at low mean flow Mach numbers, and for the wall point‐pressure spectrum at arbitrary Mach number.
