The description on its file description page there is shown below.
An attempt at 10 seconds of inverse A-weighted "gray noise". Generated by Adobe Audition from the same WAV file as Image:White noise.ogg by plugging in values from the weighting filter equations in the FFT filter. Normalized to −1 dB.
Possibly not mathematically perfect due to Audition or encoding.
