Introduction to Active Noise Cancellation

Active noise cancellation (ANC) is a technology that can be used to reduce unwanted sound. It is most commonly used in headphones and earbuds, but can also be found in some speakers and other audio devices. ANC works by creating a sound wave that cancels out the noise around you.

There are two main types of ANC: feedback and feed-forward. Feedback ANC is the more common type and uses a microphone to pick up the noise around you. This information is then processed and used to create a sound wave that cancels out the noise. Feed-forward ANC is less common and uses sensors to pick up the noise. This information is then used to create a sound wave that cancels out the noise before it even reaches your ears.

ANC can be used to reduce a variety of noises, including background chatter, traffic noise, and airplane cabin noise. It can also be helpful for people who work in noisy environments or who have hearing loss.

How Does Active Noise Cancellation (ANC) Work?

ANC, or active noise cancellation, is a technology that can be used in headphones and earbuds to cancel out unwanted ambient noise. It works by using microphones to pick up on sound waves coming from outside sources and then producing an opposing waveform that effectively cancels out the unwanted noise.

ANC can be very effective at reducing low-frequency sounds like the rumble of a plane engine, but it is not as effective at canceling out higher-frequency sounds like human voices. However, there are some high-end ANC headphones that use multiple microphones and advanced algorithms to provide better noise cancellation across a wider range of frequencies.

Overall, ANC can be a great way to improve your listening experience in noisy environments, whether you’re trying to block out the chatter of a busy office or you want to enjoy your music without being interrupted by outside noise.

Pros and Cons of ANC Technology

There are many different opinions on the pros and cons of active noise cancellation (ANC) technology. Some believe that ANC technology is beneficial because it can help to reduce or eliminate unwanted noise. Others believe that ANC technology can be harmful because it can block out important sounds, like emergency sirens. Activating ANC might consume more battery. Ultimately, the decision of whether or not to use ANC technology is a personal one. Here are some things to consider when making your decision:


  • ANC technology can help to reduce or eliminate unwanted noise, which can improve concentration and productivity.
  • ANC technology can also help to improve sleep quality by blocking out disruptive noises.
  • In some cases, ANC technology may also help to reduce stress and anxiety levels.


Some people believe that active noise cancellation (ANC) technology can be harmful because it can block out important sounds, like emergency sirens. It's important to weigh the pros and cons of using this type of technology before making a decision.

Types of ANC Devices Available 

There are three main types of ANC devices available on the market: over-ear headphones, TWS earbuds, and neckbands. 

  1. Over-ear headphones are the most common type of ANC device, as they are generally the most effective at canceling out noise. They work by creating a seal around your ears, which prevents outside noise from entering. Many over-ear headphones also have active noise cancellation built-in, which uses batteries to create an additional level of noise cancellation.
  2. TWS Earbuds are another popular type of ANC device. ANC earbuds usually have small speakers that fit inside your ear canal, and they work by blocking out external noise with their snug fit. Some earbuds also have active noise cancellation, but they tend to be less effective than over-ear headphones.
  3. Noise-canceling neckbands are the latest technology to hit the market. They are designed to provide a comfortable and effective way of blocking out unwanted noise, allowing you to focus on what matters. They also come with features such as Bluetooth connectivity, voice activation, and long battery life. With these features, they make it easier than ever to stay focused and productive while on the go.

Tips for Choosing the Right ANC Device

There are a few things to keep in mind when choosing the right ANC device for you. First, consider what you will be using the device for. If you want to use it for work, then you'll want a device that is compatible with your work environment. If you plan on using it for travel, then you'll want a device that is lightweight and portable. Second, think about the noise level of your environment. If you live in a city with a lot of traffic noise, then you'll want a device that can handle that level of noise. Third, consider your budget. Active noise cancellation devices can range in price from ₹2500 to ₹45000 or even more, so it's important to find one that fits your needs and budget. Lastly, make sure to read reviews before purchasing an ANC device. There are many different devices on the market, so it's important to find one that has good reviews and meets your needs.

In a Nutshell

Active noise cancellation has now become a popular feature in many headphones, earbuds, and other audio devices. It is an effective way to reduce background noise, allowing you to enjoy your music and conversations without distraction. By understanding how ANC works, you can make sure that the device you buy is best suited for your specific needs. Whether it's simply reducing outside interference or providing total silence within a given space, active noise cancellation technology continues to evolve and offer more beneficial features with each iteration.
