Purpose

To learn about the possibility of communicating using only tin cans and some string.

Your Task

Design an experiment to test what affects the performance of a tin can telephone. You will this experiment up as a formal lab report. As much as possible you should quantify all variables you are studying. You may result to a rating system for sound quality if needed, but try to use anAndroid https://play.google.com/store/apps/details?id=kr.sira.sound&hl=en orApple app https://apps.apple.com/us/app/decibel-10th/id448155923 for measuring the decibel of the received sound if possible to use in conjunction with your rating of the clarity of the sound. Of course you will need a consistent source of sound as well.

Possible Factors

• Can size
• Can material
• String length
• String tension
• Others
