‎First appearance of an a milestone paper in the theory of accoustics - Lord Rayleigh's first paper on the theory of sounds.Certain references in Helmholtz's treatise ""Lehre von der Tonempfindungen"" ""to the properties of acoustic resonators attracted his attention and led to his first elaborate research, reported in a long paper in the Philosophical Transactions (the paper offered). This article furnishes a clear indication of the method of thinking about problems that remained characteristic of all Rayleigh's later work. He endeavored to develop the mathematical theory of the subject in a form related as closely as possible to experimentally realizable situations, and then followed up the results by the attempt at direct experimental verification....In thsi paper Rayleigh first introduced the the useful concept of the 'Acoustic Conductivity' of an orifice. It has remained a standard acoustical quantity ever since, even if rather difficult to estimate theoretically for all sort of openings.""(Robert Bruce Lindsay in his introduction to Rayleigh's Theory of Sound).‎
