What is it about?
We investigated the effects of feedback delays and amplification on both adaptive and reflexive fundamental frequency perturbation paradigms, encapsulating the variability in equipment-specific delays (3–45 ms) and amplification utilized in previous experiments.

Why is it important?
Surprisingly, we found that equipment delays below 100 ms do not affect the results of fo perturbation paradigms. We also determined that auditory feedback amplification of +5 dB relative to microphone is sufficient to elicit robust compensatory responses for fundamental frequency perturbations
