ANC noise reduction technology is to eliminate noise by analyzing the sound waves of noise and sending out reverse sound waves to neutralize the noise. The advantage of ANC active noise reduction headphones lies in its remarkable control effect on low-frequency noise, which can effectively isolate low-frequency noise and reduce the impact of noise on us.
Generally speaking, the effective frequency of ANC active noise reduction is between 50 Hz and 2 kHz. For the noise exceeding 2KHz, the noise reduction earphone can be combined with passive noise reduction method through the structural design and material selection of the earphone. When active noise reduction is turned on, the power consumption of headphones will increase, and the battery life will be 20%. It is necessary to turn on this function manually.
Application scope of ANC active noise reduction
The noise during the journey will greatly affect our experience. On the plane, the sound of the engine, the sound of the airflow and the conversation of other passengers will make our journey very uncomfortable. On the train or bus, engine noise, tire friction noise and road noise will interfere with our rest. In hotels or youth hostels, the sound insulation effect is often unsatisfactory, and the surrounding noise will also affect our sleep.
Whether in the gym or outdoor sports, noise will affect our sports experience. In the gym, music, musical instruments and other people's conversation will affect our attention. In outdoor sports, environmental noise such as vehicle noise and human voice will also interfere with our experience.
