This webpage was created as a home for the details on my noise-cancelling circuit and my presentation materials. The circuit itself was the result of my work in PHYS 420C (Fall/Winter 2016) at the Univerity of British Columbia. Everyone browsing this webpage is free to make use of the documentation that provided here. As part of the course, I created a circuit to demonstrate noise-cancelling and presented this demo to an Electronics 11/12 class in a high-school. I explained all the basics of sound and waves (as described on these pages) and showed off my circuit in a 50 minute presentation.
PHYS 420C is a class offered at UBC by the Department of Physics and Astronomy (PHAS) for upper level undergraduate students. It is a demonstrations course and students are to design and construct a demonstration that exhibits physics phenomenon. Students work independently under the guidance of Professors Andrzej Kotlicki and Janis McKenna to develop projects. Students then present their demonstration to the class and afterwards in a local school.
Demonstrations are ranged at the elementary and high-school level and over the years have ranged from discussions on circuitry to understanding gravity to the physics of hot air balloons. Check this webpage out for some great links to other student webpages and the rest of the UBC PHAS Outreach website.
I am a student in PHAS pursuing a degree in Physics. I am in a dual degree, concurrently working towards a bachelors in Violin Performance with the School of Music at UBC. As a result, I am very interested in the nature of sound and acoustics and its numerous applications. These interests are not limited to just sound, however, as radiofrequency waves are used in medical imaging, such as with MRI, and signal processing and analysis is used heavily when working with circuitry. The knowledge found within these pages can be applied to many branches of physics, and so my interests are also diverse. I am also fascinated by the mechanics of vehicles, such as cars, airplanes, and ships of all kinds, and I am currently learning the Violin Concerto by William Walton: here's a link to a playlist on YouTube.
