Which term describes echolocation?

• A. Auditory Skill - Localization
• B. Unilateral Hearing Loss
• C. Echolocation
• D. Phases of Adjustment to Blindness

Answer: (C)

Echolocation is the process of using sound reflections to determine what’s around you. A person makes a sound—such as a tongue-click or a simple vocalization—and listens for the echoes that bounce back from nearby objects. By interpreting these echoes, they can infer information about distance, size, shape, and position of obstacles, which helps with spatial awareness and navigation. In orientation and mobility, recognizing echolocation as a deliberate perceptual skill explains why some travelers can “sense” objects in their environment beyond what their ears alone would provide.

This is different from localization, which is a broader auditory skill that identifies where a sound originates but doesn’t necessarily rely on self-generated echoes to map the environment. Unilateral hearing loss is a medical condition affecting hearing in one ear, not the active process of using echoes. Phases of Adjustment to Blindness describe psychological stages of coping, not a perceptual technique.
