Technology evolves constantly, and companies constantly bring new innovations to the market. In recent years, earphones and earbuds have undergone many changes, including improvements in sound quality, calling features, and the addition of noise cancellation. This feature, now available in mid-range earphones, is worth understanding. Let’s learn more about the Noise Cancellation feature and some of the most popular Noise Cancelling Earbuds in India.
Do you know the first commercially available noise-canceling headphones were introduced by Bose Corporation in 2000?
What is noise cancellation?
Noise cancellation refers to the technology that reduces unwanted background noise from audio signals. It works by generating sound waves that counteract and cancel out the ambient noise. This results in a clearer and more isolated sound experience. Noise cancellation is widely used in headphones, earbuds, and other audio devices, making it easier to listen to music, make phone calls, or watch videos in noisy environments.
How does the Noise Cancellation feature work?
Noise cancellation technology works by using microphones to pick up external sound and then creating an inverse sound wave to cancel it out.
There are two main types of noise canceling: active and passive. Passive noise canceling uses physical barriers, such as thick earpads or noise-isolating earbuds, to block out noise. Active noise canceling, on the other hand, uses electronics to actively generate sound waves that cancel out external noise.
In active noise-canceling headphones, microphones located on the outside of the earcups pick up external noise, and the noise-canceling processor creates an inverse sound wave to cancel it out. This processed sound wave is then combined with the audio signal from the headphones, producing a much clearer and quieter sound. The effect is most noticeable in low-frequency noise, such as the hum of an airplane engine or the rumble of a train.
Why is an active noise cancellation feature necessary?
Active noise cancellation technology is necessary because it helps to provide a more enjoyable and immersive audio experience in noisy environments. Without active noise canceling, external noise can easily overpower the audio being played through headphones, making it difficult to hear the music, dialogue, or other audio content.
By canceling out external noise, active noise-cancelling headphones allow the user to better focus on the audio being played and can result in a more enjoyable and immersive listening experience. This can be especially important for frequent travelers or commuters who need to block out noise in noisy environments, or for people who need to concentrate in a noisy workplace.
Additionally, by reducing the need to turn up the volume to overcome external noise, active noise canceling can help to protect the listener’s hearing. This makes it an important technology for people who use headphones regularly and want to preserve their hearing over the long term.
Noise Cancelling Earbuds
Boat, Noise, and JBL, popular audio brands, offer noise-cancellation features in some of their products. Boat offers a range of noise-canceling headphones and earbuds, including the Boat Airdopes 441 Pro and the Boat Rockerz 255 Pro+, both of which feature active noise-cancelling technology.
JBL, on the other hand, offers a wide range of noise cancelling headphones, including over-ear, on-ear, in-ear, and neckband styles, with models such as the JBL Quantum 800 and the JBL Free X offering active noise cancelling.
