A doorbell that uses both sound and flashing lights when activated exemplifies which Universal Design principle?

• A. Equitable Use
• B. Perceptible Information
• C. Flexibility in Use
• D. Low Physical Effort

Answer: (B)

The principle of Universal Design exemplified by a doorbell that uses both sound and flashing lights when activated is perceptible information. This principle emphasizes the importance of providing information in ways that can be perceived by all users, regardless of their sensory abilities. By combining auditory signals (the sound of the doorbell) and visual signals (the flashing lights), the doorbell ensures that individuals with different sensory preferences or limitations can effectively perceive the notification that someone is at the door. This dual functionality enhances accessibility, as it accommodates those who may be hard of hearing, as well as those who may have visual impairments, thereby increasing overall usability for a broader audience.
