White noise tends to reduce ringing the most compared to pink noise or brown noise. This is because white noise contains all frequencies at equal intensity, which helps mask or drown out specific frequencies that contribute to ringing or tinnitus. Pink noise and brown noise have different frequency distributions, with pink noise having more power in the lower frequencies and brown noise having more power in the even lower frequencies. While they can also provide some masking effect, the broad spectrum of white noise makes it more effective in reducing ringing in the ears.
