Light Device for School Bell Notification

People sitting next to each other at school often watch TikTok or YouTube on their smartphones at high volume, and some of them wear earplugs or ear muffs for independent study. However, that way they cannot hear the pre-bell or their name being called. Therefore, we propose a device that uses a microphone to pick up the pre-bell of a pre-registered school and alerts the students with a light. This device can also register a person's name, so even if they are wearing earplugs, they will not miss their name being called. Furthermore, this device is useful for the hearing impaired and those with hearing sensitivity.
