How Noise Cancelling Headphones Works? – Types of Noise Cancellation

There are two kinds of noise canceling headphones available in the market. You will find the passive noise cancellation headphones and the active noise cancellation headphones. These technologies are different.

The passive technology will have the insulated construction of headphones to block the external noise up to some extent. While most of the in-ear headphones come with an external sound reduction system; and they block sound in a better way because it’s already inside the ear.

On the other hand, active noise cancellation headphones are designed to cut out the background noises more sophisticatedly. In short, you can say that the ANC headphones will try to block the background noise up to 100 percent.

1. Passive Noise Cancellation Headphones

The passive noise cancellation headphones don’t provide the most impressive results in blocking out the noise. You will have a cheaper investment in noise canceling headphones with the passive type. Most of the headphones with this technology are starting from 100 dollars.

Furthermore, passive noise canceling will cancel the external noise to some extent. For instance, the headphones will block the sound up to 25 decibels in most cases. The headphones come with large drivers, and you will have noise isolation. This kind of headphones is great for blocking the noises at the lower frequency levels.

The headphones have a special chip inside them to capture the sound from the background. After capturing the sound, the headphone emits it in the headphone’s speaker, but they are reversed 180 degrees from the right waves. In this way, the headphones block the external noises.

Is It Safe To Use Headphones With The Noise Cancelling Technology?

The noise cancelling headphones are safe to use. However, you should keep the sound level on the medium level. Listening to music at very high tones is not safe. You will be completely safe while listening to music with any noise canceling headphones, whether they have active or passive technology.

Does The Noise Cancelling Headphones Completely Block The External Noises?

There are several headphones that can completely block external noises. Most of the headphones with ANC can block the sound up to 1 kHz. The headphones with the passive noise canceling cannot block the noise with the higher frequency range. Thus, if you want to block the sounds that are very loud then choose ANC headphones.
