sound direction can be inferred from temporal differences of sound arrival at each ear. Jeffress model accomplishes this by mapping time into space with delay lines: spatially arranged units are activated depending on when inputs from both ears arrive simultaneously at the unit. pic.twitter.com/rgfHUowHH5

ok, imagine you have an oscillation that is not symmetric around 0 (small direct current shift) with some amplitude modulation, for instance with 1/f-dynamics. ➡️ then these 1/f-dynamics will show up in low frequency part of spectrum (red); in addition to around oscillation peak (yellow).
