The Modified Hopkins-Stryker Equation

Document Thumbnail

From the original work of Hopkins and Stryker in 1948 through its development by Beranek in 1949 and its use by Davis in 1968 and Boner in 1969 in acoustic-gain calculations, the Hopkins-Stryker equation has proved highly useful to a myriad of users. In recent years this versatile tool has been modified in light of measurements by Peutz and Davis to account for multiple sources, semireverberant spaces, modifiers of critical distance, and various electroacoustic modifiers of the ratio of direct sound to reverberant sound. A thorough discussion of these modifications and their proper application in acoustic calculations is given.
