(1) CVC is the abbreviation of English (Clear Voice Capture). It is a software noise reduction technology. Its principle is to suppress multiple types of reverberation noise through the noise reduction software and microphone built into the headset.
(2) DSP is an abbreviation of English (digital signal processing), and its working principle: the microphone collects external environmental noise, and then through the noise reduction system function inside the headset, it replicates and generates a reverse sound wave equal to the external environmental noise to cancel the noise, So as to achieve a better noise reduction effect.
The difference between the two:
1. The beneficiaries are different. DSP technology mainly benefits the headset user, while CVC mainly benefits the other party on the call.
2. For different objects, CVC technology is mainly for the echo generated during the call, and DSP is mainly for the high and low-frequency noise in the external environment.
In the final analysis, the earphones with DSP and CVC noise reduction technology can effectively reduce the noise of the external environment of the call, and significantly improve the sound quality of the earphone for calls and songs. Noise-canceling headphones reduce the impact of surrounding noise on the basis of audio transmission, making the use of headphones more high-quality.
