Noise Cancellation: How Does it Work?
Noise cancellation is often used in aviation, and the term is also popular in the consumer electronics industry. It’s a process that reduces unwanted sound by adding a second sound wave of the opposite phase, which cancels out the original sound wave.
Noise cancellation is not just useful for airplanes, as it can also be used to reduce noise pollution and create a more peaceful environment. Here’s how it works? [Read more…] about Noise Cancellation: How Does it Work?
