In this audio, the prominent sound is that of a vacuum cleaner operating. It is a consistent, low hum that is immediately recognizable. Suddenly, there's an abrupt, clattering noise, like multiple small, hard objects being sucked up. These are the pearls, as indicated by the title. The sound is akin to tiny marbles bouncing in a tube or pipe, tinkling against each other and the interior of the vacuum cleaner pipe. They create a sharp contrast against the monotone hum of the vacuum cleaner. The pearls' journey through the tube is swift, creating a sense of urgency. Finally, the clattering subsides, leaving behind the steady hum of the vacuum cleaner once more.
