The audio begins with a sharp, short beep, reminiscent of a digital multimeter at work. This beep is high-pitched, piercing the silence with its distinctive sound. After a brief pause, there's a repetition of this beep, maintaining its consistent high pitch. Then, a noticeable variation occurs; the beep extends into a longer, sustained tone, still maintaining the high pitch, but now filling the air with its resonating sound. The beeping then reverts back to its original short form, creating a rhythmic pattern of short beeps followed by a longer, drawn-out beep. This alternating pattern of high-pitched, short, and long beeps continues throughout the audio, painting an audible picture of a digital multimeter in operation.
