Sound wave attenuation system for e.g. heat engine, has semi-sphere diffusing gas/sound or air/sound mixture, where sound waves contained in gas or air reflects inside another semi-sphere for rising in counter-direction of mixture in space
Sound wave attenuation system for e.g. heat engine, has semi-sphere diffusing gas/sound or air/sound mixture, where sound waves contained in gas or air reflects inside another semi-sphere for rising in counter-direction of mixture in space
The system has a semi-sphere (3) whose external part diffuses gas/sound or air/sound mixture, which strikes each other to compress gas and circulates along an outlet tube (6). Sound waves contained in gas or air circumvents the tube and reflects inside a semi-sphere (2`) for rising in counter-direction of the gas/sound mixture in a space between interior of a semi-sphere (2) and exterior of the semi-sphere (3) towards an emission point.
