With the development of people’s living standards in recent years, the market demand for noise-canceling headphones has gradually increased. When consumers buy noise-canceling headphones, they will always hear businesses promoting the CVC and DSP noise-canceling functions of the headphones. Many businesses describe this, but many consumers still don’t understand the difference between the two. In response to such a technical problem, Lilinxin headphone manufacturer today will give you a popular science on the working principles and differences between the two.

(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.
