Building a Noise Canceling Solution
How does sound travel?
To build a noise canceling solution, it is important to first understand how sound travels. Use these resources to learn more about the science of sound.
What mathematical and technological tools can I use to address the Challenge?
Use this math resource to learn how trigonometric functions can help you design and prototype your noise canceling solution.
The following resources can help you build a prototype of your solution. The usage of the resources is not required to complete the challenge.
These technology tools will help you find the information you need to design your noise canceling solution.
- Youlean provides an online loudness meter that allows you to detect the decibels of any noise that your computer microphone picks up. Just play your noise near your computer, or a video of your noise on your computer, and write down what the meter shows!
- Academo provides an oscilloscope for easy recording of sounds. Oscilloscopes are used to measure frequency of sounds, and this tool will provide you with a graphical representation of the sound wave to analyze for frequency.
