Noise can be described as which of the following?

Explanation:
Noise is a complex, broad-spectrum sound whose energy is spread across many frequencies and that changes over time. That makes it a chaotic mix of sounds with varying frequency and intensity. In real environments, there isn’t just one steady tone; instead, energy shifts across a range of frequencies, producing an aperiodic, evolving sound. A single-frequency tone would be a pure tone, a periodic repeating signal is predictable and repetitive, and a quiet background sound doesn’t reflect the variability and energy typical of workplace noise.
