The audio titled "Drum Scrubbing" begins with a steady, humming background noise. It's reminiscent of a running electric motor, pulsating and constant. Suddenly, a rhythmic scrubbing sound comes to the forefront. It's a scraping, almost abrasive noise that seems to dance in sync with the humming. It's reminiscent of a drumstick dragging across the surface of a drum, creating an interesting fusion of sound between the mechanical and the musical. The scrubbing rhythm is relentless, creating an intricate pattern amidst the unchanging hum of the electric background. This sound continues, ebbing and flowing in intensity but always present, adding a unique texture to the audio landscape. The electric hum and the scrubbing drum combine to create an immersive auditory experience, a symphony of noise that is both intriguing and oddly harmonious. The audio ends with the fading echo of the last scrub on the drum, leaving behind the steady electric hum before that too slowly fades into silence.
