This sound is used online as a simple fan or ventilator background effect rather than a quote-driven meme. Short household noise clips like this spread because they are easy to drop into reaction edits, skits, prank audios, and ambient scenes without needing much setup. Its appeal comes from how recognizable the steady hum is: listeners immediately understand the setting. Creators keep using fan noise when they want to suggest heat, drowsiness, silence, or an ordinary room with minimal visual explanation.
