TABLE II.

Effects of additive acoustic noise on PLV strength at harmonic frequencies of F₀ in Experiment 1. Bold frequencies had PLV values that were significantly smaller in noise than in quiet. The noise had a statistically significant effect on FFR_ENV at harmonics 200–800 Hz, but not at the fundamental frequency.
