What are the differences between Noise Cancelling Headphones and without Noise Cancelling technology?

Noise Cancelling Headphones are very popular nowadays and most people love these headphones because these headphones also provide premium sound quality like other headphones. These types of noise cancelling earbuds or in-ear headphones are really good that is why; they attract most of the customers to buy these headphones. Find out more about Noise Cancelling Headphones below.

There are different types of headphones in the market, for example, wireless headphones, earbuds, noise cancelling etc. If you are currently looking for a pair of headphones, you might wonder what the differences are between Noise Cancelling Headphones and without Noise Cancelling.

The main difference is that these Noise-cancelling Headphones completely block the external noise and can give you a peaceful environment to enjoy your favourite music tracks or audio files without any disturbance or distraction. There are three types of noise-cancelling headphones available on the market: active noise cancellation, passive noise isolation and hybrid noise cancellation.

The physics of active noise cancellation

Active Noise Cancellation or ANC works by producing sound waves that are the exact opposite of noise-producing waves, this process cuts off the external noise and provides you with a peaceful environment to enjoy your favourite music tracks. The only drawback is that these headphones are very bulky in size and weigh some additional ounces which can be annoying while travelling.

Headphones can be used in a variety of settings such as in the gym, offices, homes, airports, public transport. Sometimes, the noise around might be distracting when you are listening to your music. Now, here’s how Noise Cancelling Headphones can be a big help. Noise-cancelling headphones have a technology to reduce noises. 

Noise Cancelling Headphones differs from noise reduction and passive reduction, which involves active technology. The first headphones that incorporated the first Acoustic Noise Cancelling (ANC) is Bose. Noise cancelling headphones use powered technology, which means they require energy (such as a rechargeable battery) to function. Remember that even if you don’t have power, you’ll get the physical benefit of noise reduction by simply wearing the headphones. When you turn them on, the technology comes into play.

What is the process of noise cancellation?

Noise-cancelling headphones use microphones to check the surrounding noise and create an “anti-noise” that’s 180° out of phase with it so they effectively cancel each other out when you wear these headphones. This technology is called “Active Noise Cancellation.”

Noise-cancelling headphones monitor the environment and prevent unwanted noise from reaching your ears. To effectively “cancelling out” sounds, the microphones inside the earcups or earbuds will listen to external noise frequencies and emit the opposite signal so that both sets of sounds get cancelled when the soundwaves collide. 

Headphones with ANC is effective at regulating low, sustained sounds such as those produced by aeroplanes and vehicles engine. These sounds are at a high frequency in their sound waves thus it does not work well with ANC technology. Screaming children’s sound cannot be filtered out because it is in a much higher frequency. We might need to wait longer for the technology to improve in order to filter out higher frequency sounds.

The Benefits of Noise Cancelling Headphones 

The majority prefer noise-cancelling headphones mainly because of the silence. You can easily get distracted if you are surrounded by various noises when working or concentrating on doing something. Active noise cancellation can reduce outside noise and makes it easier for you to focus.

You can clearly get the noise-cancelling technology kicking in when you’re on a plane. A good pair of noise cancellation headphones can often completely filter out an aeroplane’s loud engine sound, so you can sleep easily in a noisy environment.

What are the characteristics of Noise Cancelling Headphones that you should be looking for?

The earcups and earpads of noise cancelling headphones are designed to block high-frequency sounds, such as human voices or howling dogs. By utilizing an item like active noise cancellation headphones, you may create a physical barrier between your ears and the noises you don’t want to hear.

These headphones, which are made of materials that won’t cause hearing damage, provide several advantages for frequent travellers who don’t want to hear an annoying aeroplane hum or individuals with sensitive eardrums who find in-ear plugs uncomfortable.

It also depends on what and where you are planning to use active noise-cancelling headphones. It won’t make an obvious difference if you are planning to use noise cancelling headphones indoors or in a quiet environment. If you plan to purchase noise-cancelling headphones, do take note that they can only be effective in certain circumstances.

There are a few solutions if you just want to block out human voices and other higher-frequency sounds. If your cheaper pair of passive headphones isn’t cutting it for sound blocking, consider investing in over-ear closed-back headphones. The majority of high-quality recording headphones will perform well at reducing irritating noises like kids playing or coworkers chatting!
