This paper reviews the result of laboratory tests in wave flumes to determine the reflection and transmission coefficients (Cr and Ct, respectively) through single perforated sheets.It has been shown that these coefficients can be calculated by using two new formulas which relate Cr and Ct to the wave-screen parameter.This parameter is the ratio of the product of discharge coefficient and the porosity of the sheet to the root square of wave steepness in deep water.
