SILENCING APPARATUS

摘要

PURPOSE: A silencing apparatus is provided to reduce energy from the wave of a noise with respect to a noise having a specific location or direction of a noise source or a noise traveling in a predetermined direction. CONSTITUTION: The apparatus comprises a sound wave reflection plate(1) having a focal point(5) and a sound wave interferer(2) for stimulating the consumption of a sound energy focused on the sound wave reflecting plate. A sound wave inlet port(3) is installed which has a minimum size required for introducing the sound focused on the focal point of the sound wave plate.
