Noise-cancelling headphones, as the name suggests. Literally we can understand that it is a headset that can reduce noise, but in fact, there is a big way to master the noise-reducing headphones. Noise canceling headphones can be divided into "active noise reduction" and "passive noise reduction" headphones. The noise canceling earphone can eliminate the environmental noise, provide a quiet and peaceful listening environment for the earphone user, and can avoid the behavior of having to increase the volume of the music due to the interference of the environmental noise, and has a certain protection effect on the hearing of the human ear. In life, if you are a business person, or a friend who often travels on an airplane, I believe that there should be a personal experience of aircraft noise. The reason why the aircraft is so tired is that it has a great correlation with the long-term noise environment. In addition to causing damage to human hearing, the roar of the engine will also have a great impact on the entire human physiological environment, leading to psychological and mental fatigue and fatigue. In the long run, fatigue will occur. It is easy to get tired and affects work efficiency. In the long run, it will cause symptoms such as insomnia, tinnitus and dreams, fatigue, and memory loss. Therefore, at this time, if there is an active noise canceling earphone, it can be very good to avoid these situations. The following small series will focus on what passive noise reduction headphones, passive noise reduction is the use of plastic, foam, fabric and other composite materials, to achieve a simple physical noise reduction method, such as we often on TV The American military headphones that are seen, or the earphones of the large earmuffs used by the airport ground staff are basically passive noise canceling headphones. Passive noise reduction headphones mainly rely on good airtightness and material properties to keep noise out, but passive noise reduction can only be used for higher frequency sounds above 500Hz, especially for noise above 1KHz. Headphones will exhibit some passive noise reduction, but it will cost a lot to get better noise reduction and low frequency noise. It is also because passive noise reduction is powerless for many low-frequency noises, which has contributed to the development of active noise reduction. Noise-cancelling headphones have shown a good upward trend in recent years. Among some earphone products that we are familiar with, noise reduction has become a standard. Brands such as BOSE, BEATS, and Iron Triangle have already popularized noise reduction in headsets. I believe that the advantages of noise reduction headphones are It will soon attract more consumers and listen to the ultimate sense of hearing from the noise reduction function.
