FIELD: mechanical engineering.
SUBSTANCE: invention relates to device designed for suppression of aerodynamic noise of pneumatic equipment and exhaust systems of compressed gas or air. Proposed noise silencer contains intake branch pipe and housing made of porous material and rigidly connected with intake branch pipe. Housing is made sectional and it consists of cylindrical and spherical shells assembled into integral unit. Cylindrical shell is provided with additional holes made in ring sections at height "b" from base of intake branch pipe to section located at height "h", with center-to-center layer-by-layer distance "c". Holes are arranged at angle of 60° relative to each other forming angles with vertices pointed from axis of shell. Hole is made on top of spherical shell. Ratio of height of housing H to diameter D of cylindrical shell is within the range of optimum values h/D=1.5-3.0.
EFFECT: improved efficiency of noise suppression.
