The sound is based on the Emergency SOS alert built into Google Pixel phones, a safety feature intended to draw attention and call for help in an emergency. As Pixel phones became widely used, clips of the distinctive alarm began circulating on soundboards and in short videos, often boosted in volume so the siren stands out over music and dialogue. This louder version is popular precisely because it preserves the recognisable phone alarm while making it punchy enough for edits, pranks and reaction clips.
