Abstract: The study presented here explored theories that account for echolocation and established an audiometric test battery for blind persons that is designed to predict success in echolocation. Statistical analyses revealed significant positive correlations between particular auditory measures and echolocation performance. No relationships were found between high-frequency hearing sensitivity and echolocation performance.
