Creating personalized head-related impulse responses is critically important for visually impaired people using electronic travel aids. This study demonstrates an efficient means of generating responses for thousands of locations in about 10 minutes. Verification trials, which measured listeners’ ability to accurately locate virtual sound sources, had average errors in azimuth ranging from 9 to 24 degrees. Such accuracies are sufficient for implementing obstacle sonification for travel aids.
