The 'RT If You Can Hear This Image' meme is a popular social media trope, primarily on platforms like Twitter, that leverages shared cultural nostalgia through visual-auditory synesthesia. The meme features a static image of something with a very distinct, recognizable sound—such as the THX intro, the PlayStation 2 startup screen, or a specific cartoon character's laugh—accompanied by a call to action to retweet if the viewer can 'hear' it. It gained massive popularity in the late 2010s as a viral engagement tactic, allowing users to bond over collective memories of media and technology. The meme thrives on the psychological phenomenon where a strong visual cue triggers the brain to play back the associated audio, turning a silent picture into a loud, nostalgic experience.
