Abstract
A number of variations may include a product for use with a turbocharger system may include a compressor wheel for charging a flow stream. A housing may be disposed around the compressor wheel, defining an inlet passage and a discharge passage. The flow stream may extend through the inlet passage, around the compressor wheel and through the outlet passage. The inlet passage may be configured to impart a supersonic speed to the flow stream to inhibit sound from propagating against the flow stream through the inlet passage.
