The hsh hsh sound comes from the Arabic word for hushing and shooing, written هش هش, and circulates online as a short reaction clip rather than a sourced recording. Its meaning travels well even without Arabic, because the breathy repeated shush is understood in almost any language as be quiet or go away. Short video editors and soundboard users keep reusing it for that instant readability, dropping it into gaming clips, pet videos and classroom style sketches where a calm voice trying to restore order becomes the joke itself.
