How to choose Over Ear Active Noise Cancelling Headphonesfor beginners? The difference between active noise canceling and passive noise canceling headphones
When it comes to the noise reduction technology of headphones, there are currently two main categories of active noise reduction and passive noise reduction. What are the advantages and disadvantages of each?
The most common one we see is passive noise reduction. This is very easy to understand, which is to perform noise reduction processing from the physical level. The disadvantage of passive noise reduction is that most of the sounds it shields are high-frequency sounds, but it does not have such a good isolation effect for some low-frequency noises.
Active noise reduction uses a completely different method to process noise. The principle is to pick up the noise sound waves in the environment, and then the sound generation unit emits opposite sound waves to cancel the noise. It has obvious noise reduction effect for both high and low frequency noise.
The current active noise-cancelling headphones also have quite good sound quality performance, and their applicability is broader than passive noise-cancelling. Therefore, it is recommended that friends who have the conditions still choose active noise-cancelling headphones.
