There are two types of noise canceling headphones, active noise reduction and passive noise reduction.
The active noise reduction function is to generate a reverse sound wave equal to the external noise through the noise reduction system, and neutralize the noise, thereby achieving the effect of noise reduction. Active noise canceling headphones with noise-reducing circuits that compete with external noise. Most of them use a large head-mounted design, which can be used to block external noise by using earplugs and earphone casings, and to perform the first round of sound insulation. There is plenty of room to install active noise reduction circuits and power supplies.
Passive noise canceling headphones mainly form an enclosed space by surrounding the ear, or use soundproof materials such as silicone earplugs to block external noise. Since the noise is not processed by the noise reduction circuit chip, generally only high frequency noise is blocked, and the noise reduction effect on the low frequency noise is not obvious.
Application:
1: Business people, because of frequent business trips, especially those who travel between different cities every day, they must hate the noise in the cabin. If there is a noise-cancelling earphone, they will be able to stay away from these noises. Relax by enjoying the music.
