Phase cancellation is a phenomenon that occurs when two sound waves meet and interfere with each other, leading to a reduction or complete nullification of the sound at certain frequencies. This effect happens when the waves are out of phase, meaning that their peaks and troughs align in a way that causes them to effectively cancel each other out. Understanding phase cancellation is crucial in various areas like directivity, active noise control principles, and their applications, as it can influence how sound is perceived and managed in different environments.
congrats on reading the definition of Phase Cancellation. now let's actually learn it.
