Dangers and disasters are inherent in life, particularly when surroundings are unfamiliar,
and reliance is solely on hearing. This study aims to develop an emergency broadcasting
system for the Philippine National School for the Blind, ensuring that visually impaired
students can evacuate safely and swiftly during emergency situations. The system is
equipped with speakers that provide instructions and live emergency broadcasts. The
prototype was developed using 10-watt, 8-ohm, and 0.5-watt, 8-ohm speakers with a
recording module and amplifiers to enhance sound quality and loudness. The system
includes drill, emergency, and safe zone pre-recorded options which can manually activate
when students reach the safe zone. The prototype was tested by comparing evacuation
times during a previous drill after installation of the prototype. Results showed a significant
reduction in evacuation time from 5 minutes to 2 minutes and 30 seconds, confirming
effectiveness and reliability of the system. Furthermore, 50 respondents, comprising
students, officials, and teachers, evaluated the prototype and rated it as “Highly
Acceptable”.
