You might see noise-canceling headphones most often on the domes of frequent travelers, shielding their ears as they try to tune out the many other sounds on the plane or train. But they certainly aren’t the only ones who can benefit from tuning out ambient noise. Many people who work in open offices turn to noise-canceling headphones when they need to focus. And if you still find yourself working from home, a good pair may be essential to drown out your housemates’ chatter and get to work. Here, we’ve rounded up some of the best, as well as provide some background on the tech.
How Noise Cancelation Works
More headphones than ever come equipped with noise-cancellation features, including regular over-ear models and compact, wireless earbuds. They do more than simply physically block sounds from entering your ear canal—active noise cancellation (ANC) actually uses a microphone to process the ambient sound, and then the circuitry produces “opposite” sound waves to reduce the unwanted vibrations. While this doesn’t necessarily eliminate all external sound, it can block about 70 percent of ambient noise, effectively dulling lower-frequency tones like the roar of an airplane or traffic or the bustling of a coffee shop.
For many people who just want to play music or podcasts to block sound, a pair of regular headphones or earbuds may do the trick for simply drowning out the babble. But, according to The Guardian, exposure to too much background noise for several hours a day can raise stress levels and even cause permanent hearing damage over time. So many travelers and big-city commuters may find the extra cost of ANC worthwhile for their general health and wellness.
