The paper is an appraisal of the current status of our understanding of pressure fluctuations beneath turbulent boundary layers. The review is oriented towards discussion of the significant papers that have led us to our current understanding of the phenomena of pressure fluctuations and turbulence in boundary layers. The application of our knowledge of pressure fluctuations toward the solutions of engineering problems is not considered. The review concentrates primarily upon the experimentally measured results but theoretical results are discussed when appropriate. The topics treated include convection, decay, power spectrum, mean square and spatial scale of wall pressure fluctuations. There is also a discussion of the effects of pressure gradient on the wall pressure. /AUTHOR/
