Bluetooth earphones usually use special noise reduction technologies to reduce the interference of external noise during calls. These technologies are designed to ensure that both parties can hear each other clearly and improve the accuracy and comfort of calls.
Among them, ENC (Environmental Noise Cancellation) technology is a common call noise reduction technology in Bluetooth earphones. ENC technology collects environmental noise through the dual microphone array built into the headset, and then subtracts these noises from the signal received by the call microphone through algorithm processing, thereby improving call clarity.
In addition to ENC technology, CVC (Clear Voice Capture) noise reduction technology is also widely used in Bluetooth earphone calls. CVC technology focuses on optimizing and filtering echoes and background noise during calls, and reduces the impact of these noises on call quality through software algorithms.
In addition, some high-end Bluetooth earphones also use more advanced call noise reduction technologies, such as Qualcomm CVC noise reduction technology. This technology filters the signal received by the call microphone through the chip inside the bluetooth earphone, which can more accurately identify and reduce environmental noise to ensure the clarity of the call.
It should be noted that different bluetooth earphone brands may use different call noise reduction technologies, so the call effect will also be different. When choosing a bluetooth earphone, consumers can choose products with suitable call noise reduction technology according to their needs and budget.
In addition, in order to obtain better call effects, in addition to choosing a bluetooth earphone with call noise reduction technology, you also need to pay attention to the wearing method and environment of the earphone. The correct wearing method can ensure that the microphone can better capture the sound, while a quiet environment can reduce the interference of external noise.
The bluetooth earphone does apply specific noise reduction technologies to improve the quality of calls. These technologies reduce the interference of environmental noise and ensure that both parties can hear each other clearly, thereby improving the accuracy and comfort of the call.
