sound interference



After trying to use my my versace headphones I thought I would look up how the interference from my little brother Micah's mouth altered the sound that went into my ears. I found that when two waves meet, there can be two types of interference; constructive and destructive. Constructive inteference is when two waveforms meet and are added together. The peaks add with the peaks, and the troughs add with the troughs- which creates a louder sound. Destructive interference occurs when two waves are out of phase. For example, if two waveforms that are exactly the same are added, the amplitude doubles, which makes a louder sound. But, when two opposite waveforms are added, they cancel each other out.
