Abstract
Gas liquid mixtures readily absorb the wave energy of noise and thus reduce noise intensity. By circulating gas liquid mixtures through jackets surrounding noisy machines, such as internal combustion engines, undesirable noise can be reduced.
Claims6
The combustion of a noisy machine:
- wherein the improvement comprises:
- jacket means for containing a fluid and comprising a fluid inlet and a fluid outlet;
- positioning means for positioning said jacket means for containing to largely surround said noisy machine;
- a source of gas;
- a source of liquid comprising a liquid source inlet and a liquid source outlet;
- mixer means for creating a mixture of gas bubbles within a liquid comprising a gas inlet, a liquid inlet and a mixer outlet;
- means for circulating said mixture of gas bubbles in liquid from said mixer outlet through said jacket containing means from said fluid inlet thereof to said fluid outlet thereof;
- means for connecting said gas source to said gas inlet of said means for creating a mixture;
- means for connecting said liquid source outlet to said liquid inlet of said means for creating a mixture.
