Echo thresholds vary widely and do not correlate with audiometric thresholds in hearing loss.

Evidence

The echo threshold was defined as the just noticeable delay that determined whether the listeners heard one (the echo stimulus was fused with the leading stimulus) or two clicks. Roberts et al. found large variability across listeners, even when stimuli were presented at the same sensation level for the two groups. Many listeners with hearing loss had higher echo thresholds than those with normal hearing, but not all. As we have seen repeatedly in this text, no correlation was observed between audiometric threshold and echo threshold. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1590

• QUESTION: If audiometric threshold doesn’t predict echo threshold, what does predict a listener’s precedence-effect deficit? The mechanism is left unstated here.
