Enjoy this post by guest blogger and Velodyne employee, Jenny Ly. She’s a big fan of our latest headphone, the vQuiet.
Within our busy lives, sometimes it’s hard to find some peace and quiet. Nowadays, it’s considered a luxury to obtain some “silence.” Here in the Silicon Valley, noise levels are pretty high. Nonetheless, I still like living in a busy area because it keeps me on my feet. I always have something to do. So, how do I obtain some sort of silence and be in my own Zen, while taking the CalTrain to work? Noise canceling headphones, it turns out, are the solution to my problem. Hands in the air like you just don’t care!
Of course, noise cancellation technology has been around for a while. In the 1950’s, it was used for canceling noise levels in airplane and helicopter cockpits. Imagine the grueling and loud noise levels for the pilots!
Active Noise Cancelling headphones are usually more expensive because it’s harder to produce this sophisticated construction. ANC headphones contain small mics on each side to pick up the ambient noise, which is sent to noise cancellation circuitry. Sound waves are created by the headphone speakers. The internal circuitry produces sound waves that mirror the external noise. Newly added sound waves and external noise essentially cancel each other out by the time it reaches your eardrums.
Passive Noise Cancelling headphones are based on the design of the ear cups to block out noise. The size and shape of the ear cups determines how much noise level is blocked. This type of headphone is more common, not as expensive, and less costly to make. It also works best for middle and high frequencies.
Now, I’m going to put my vQuiet headphones on and play Bruno Mars’s Unorthdox Jukebox album. “Treasure! That is what you are… Honey, you’re my golden star…” Makes me want to get up and do the Charleston listening to this song!
