NoJamm the Next Generation of Eliminating Noise Pollution

Jenny X., Andrea H., Monika R., Mary L.

Our idea is a device that can reduce or cancel the source of a sound, like a blender or traffic, and even implement our device to help people who suffer with hearing disabilities, in the future. We have constructed ours, however, to reduce a specific frequency in square waves, which we have set to 500 Hertz. We are able to emit this wave from from a laptop and cell phone, where you can hear our device, affecting the volume of the wave when we present it, by reducing the noise present. In our project a 400 pin breadboard is used and coded in C++.

Anyone can suffer from hearing loss, and the chances are increased if you are exposed to loud noise over a long period of time. This happens because the sound waves and pass through your ear canal, into your eardrums, then your inner ear where there are countless tiny hair cells that are what allow you to process sounds. Over your lifetime these cells become damaged and die.

There are a lot of issues with noise. About 20% (48 million) Americans have reported some degree of hearing loss and about 60% (28.8 million) of these individuals are either in the workforce or an educational setting. Hearing loss is the third most common physical condition after arthritis and heart disease. Anyone can suffer from hearing loss, and the chances are increased if you are exposed to loud noise over a long period of time. Our project aims to contribute to the cause of hearing issue, along with many growing issues of hearing loss in poor devices and applications with technology.

We faced a few challenges when we started this project. Since the circuit is very complicated, where we were faced one of biggest struggles. Throughout this project, we had to take all of our components as frayed puzzle pieces because there were many implementations of ideas, where the physics and research was quite a challenge because our project is not on the market. The main puzzle pieces was finding pieces of information about circuits and attempting to emulate the idea of our resources, along with prewriting and rewriting the code. In doing so, the research process made us more knowledgeable about the hardware process and the project in a nutshell.

Monika is a rising junior who would like to major in Computer Science in college to become a Computer Hardware Engineer. She has also taken an interest on becoming a sign language interpreter. Mary is a rising senior who would like to major in either computer science or electrical engineering. She would also like to pursue her hobby of musical theater in college. Jenny is a rising junior who plans to survey her passions for her future career. She plans on double majoring with a focus in Computer Engineering (CE) and Political Science, due to her interest in both technology and the private sector. Andrea is a rising senior who plans to major in computer science and minor in business in her future path in college.
