Which mobility aid provides auditory guidance?

• A. White cane
• B. Electronic travel aid
• C. Guide dog
• D. Personal mobility scooter

Answer: (B)

The electronic travel aid is designed to provide auditory guidance, making it a valuable tool for individuals with visual impairments. These devices use various technologies, such as ultrasonic sensors, to detect obstacles and then convey information about the environment through sound, often using beeps or verbal instructions. This auditory feedback helps users navigate their surroundings more safely and efficiently.

In contrast, the white cane is a tactile mobility aid primarily used for detecting obstacles through touch. A guide dog assists with navigation but relies mostly on visual and situational awareness, responding to commands and environmental cues rather than providing guided auditory feedback. Lastly, a personal mobility scooter is a mode of transportation that offers physical mobility but does not interactively guide the user through auditory cues. Thus, the electronic travel aid stands out as the option specifically designed to provide auditory assistance in navigation.
