White noise carries constant power per hertz across the human hearing range

Evidence

White noise is a very specific type of noise, which is random in nature and has a constant power spectral density. Essentially, this means that when the power spectrum of white noise is plotted, it looks flat across frequency. Within the human hearing sciences, we generally assume that the frequencies contained within the white noise roughly correspond to the range of human hearing, or 20 to 20,000 Hz. … The spectrum also contains a representation of those fluctuations, but the fluctuations are relatively small and we generally treat the spectrum of white noise as being flat across frequency, particularly for long-duration white noise. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 408
