Do you often feel that you’re going to go deaf sooner than later because you blast your headphones on the top volume peak possible? Wait, you didn’t hear me? Turn your volume down some. I said, if you feel that you’re going to go deaf because of your loud volume, you probably are! Just kidding, but you get my drift. People are used to having to turn the volume up way too high in order to get everything out of their favorite song, from the high kicks to the deep rifts. If you are a victim of this practice and wish that you could find a happy medium between turning the volume down some and hearing every element in your favorite song, you might have found your answer with noise cancelling headphones.

What are Noise Cancelling Headphones?

Noise cancelling headphones fit into the new world of technology as a new way to listen to and truly enjoy the quality of music coming from you music source. The new technology has taken the world by storm, giving many people the opportunity to listen to their music without having to turn it all the way up in order to hear all of the subtleties that make it great.

The way they are able to create a crystal clear sound without you having to turn them up is by reducing the ambient (or acoustic) noise in the headset by the speakers. They placed a microphone near the ear that creates a sound wave called anti-noise. The sound wave is said to have the opposite polarity of the sound wave that arrives as the microphone. This means, when they meet, they cancel other out; this is called phase cancellation. Once phase cancellation occurs, a new sound wave is produced called destructive interference. The original sound wave is then placed a higher volume than the new sound wave, which eliminates unwanted noise. The end result is a crisp quality of music that allows you to hear every aspect of sound placed in the song.
