Introduction
In the world of TWS earphones, noise cancellation technology has become a crucial feature. It allows users to immerse themselves in their audio experience, blocking out the ambient noise of the world around them. But did you know there are two main types of noise cancellation – active and passive? And how do you choose between them? Let’s dive in.
Understanding Noise Cancellation
Active Noise Cancellation (ANC)
Active Noise Cancellation (ANC) is a more advanced type of sound-canceling technology because it requires the use of microphones and batteries1. ANC is a noise-canceling system in earphones that uses hardware and software to cut out the outside noiseThe TWS earphones or headphones are equipped with a chip and a pair of microphones specially designed to record the noise.
ANC works by producing phase-flipped sound waves that are the opposite, or “negative,” of the ambient noise, effectively canceling it and creating a quieter listening environment2. This is referred to as destructive interference3.
Passive Noise Cancellation
Passive noise cancellation, on the other hand, is a type of soundproofing that blocks out outside noises by creating barriers between the listener and the source of the noise4. The most common materials used for passive noise cancellation are foam pads or earmuffs to create a seal around the speaker, blocking outside sounds from entering3.
Active vs Passive Noise Cancellation
The main difference between active and passive noise cancellation is that active noise cancellation requires a power source, while passive noise cancellation doesn’t5. Active noise cancellation is more effective at reducing noise overall, while passive noise cancellation is better at blocking low-frequency sounds.
How to Choose Your Noise Cancelling Headphones
When choosing your TWS earphones, consider your specific needs and environment. If you’re often in noisy environments or travel frequently, ANC headphones might be more suitable for you4. However, if you’re looking for a more affordable option or don’t want to worry about charging your headphones, then passive noise cancellation could be a better fit.
Also, comfort is key. Try them on if possible and decide which type of headphones (over-ear or in-ear) you’re comfortable using6.
Finally, don’t forget to consider battery life. If you’re opting for wireless headphones with ANC, look for ones with around 25 hours of battery life6.
Conclusion
Whether you choose active or passive noise cancellation depends on your personal needs and preferences. By understanding how each technology works, you can make an informed decision and enhance your audio experience with your TWS earphones.
This article provides an in-depth look at active and passive noise cancellation technologies in TWS earphones and offers guidance on how to choose the right noise-cancelling headphones for your needs.
