ENCLOSING ACOUSTIC SHIELD Russian patent published in 2005 - IPC

FIELD: transport engineering.

SUBSTANCE: invention relates to enclosing acoustic shields designed to reduce noise from vehicles running over roads, including those running along highways, or electric trains on railways of noise from other sound sources i.e. to design of enclosing acoustic shields employing principles of multifold diffraction, sound interference and keeping reflected sound within the limits of main duct. Proposed enclosing acoustic shield has side wall and enclosing body connected to said side wall. Enclosing body of curved shape includes bent member with four bending units, each having angle of 142°.

EFFECT: provision of effective damping of noise and improved stability and possibility of use in the field, provision of adequate observation of surroundings.
