Introduction

Noise Cancelling Sine Waves Description:

In this wiki spaces, we have dedicated our time and efforts into creating a page on the topic of noise cancelling. This is to demonstrate both our knowledge of the unit circle and the application it has in real life in the form of trigonometric functions such as sin, cos and tan as well as to enrich the general pubic on the topic of sound wave. More specifically, this page is to show how sound waves are generated and shown through a sine curve, and use this data to show how technology nowadays have the capability to cancel out ambient noises to produce a clearer and more superior sound when listening to music.

In this project, we will be covering a few topics in detail: 1) How sound waves can be modelled by using a sine wave 2) How a particular sound wave can be cancelled by another sound wave 3) How this applies to life (Noise Cancelling Headphones in Particular)

Interesting Facts: 1) Noise cancelling headphones use the simple principle of inverse sine waves to cancel out ambiant noise 2) The first noise cancelling headphones were used in flight operations, and they were patented in the 1950s 3) Sound is the "pushing and pulling" of air molecules which is called compression and rarefaction. A compression is the crest of the sine wave, and the rarefaction is the trough of the sine wave. 4)The loudest sound humans can hear without feeling physical discomfort is 145decibels
