Noise-Cancellation System

I conducted an experiment to explore destructive interference in sound waves, a key principle behind noise-canceling technology. Using speakers, waveform generators, and an Arduino-based system, I examined how phase differences influence amplitude reduction, verifying predictions of interference at half-wavelength intervals.

By applying theoretical equations for wave motion, I calculated expected interference points and compared them with experimental data. Results aligned closely with predictions, demonstrating higher-frequency waves achieve interference over shorter distances. Data analysis included amplitude plots, slope comparisons, and error quantification.

This project deepened my understanding of sound wave physics, experimental design, and data analysis. It also provided hands-on experience with Arduino, Python, and oscilloscope measurements.
