Detecting acoustic signals can help with daily life to a large extent. Depending on a set frequency, one can detect lifesaving emergencies such as intruders or leaks. On top of this, once detection has been made, many different outputs can be created as a result of that detection. Once an intruder comes, the system can automatically contact authorities or if a leak is detected, the system can automatically notify the user that the leak has occurred. Detecting acoustic signals provides us with the comfort of being able to live more stress-free knowing that there is a system in place ready to detect an emergency at any time. In this work, we implemented a sound detection system that is fundamental to the functionality of devices such as alarm systems and medical devices. In addition, we tested the system using a Simulink testing and verification system which is the first verification system to be taught in undergraduate engineering programs. It involves a sound-based verification, in which, when the test passes, a particular sound of 400-490 Hz will ring. Loyola University Chicago is now the first university to have successfully completed DVT Design Verification in an Undergraduate Engineering program using Simulink. This testing and verification system has also proved to be useful in industries and companies as Simulink testing is becoming more commonly used because of its powerful model-based design and testing features.
