With the development of people’s living standards in recent years, the market demand has gradually increased. When consumers buy noise-cancelling headphones, consumers will always hear the CVC and DSP noise-cancelling functions of the headset, regardless of the description However, many consumers still do not quite understand the difference between the two. In response to such a technical problem, noise-cancelling phone headset wholesale manufacturers explain the working principles and differences between the two.
(1) CVC (Clear Voice Capture) is a software noise reduction technology. Its principle is to suppress various types of reverberation noise through the built-in noise canceling software and microphone.
(2) DSP (digital signal processing), its working principle: the microphone collects external environmental noise, and then through the function of the noise reduction system inside the headset, reproduces a reverse sound wave equal to the external environmental noise, and cancels the noise to achieve more Good noise reduction effect.
The difference between the two:
1. Different beneficiaries: DSP technology mainly benefits the headset user himself, while CVC benefits the other party of the call.
2. For different objects, CVC technology mainly targets echo generated during a call, and DSP mainly targets high and low frequency noise in external environment.
In the final analysis, the headphones using 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 calls and songs. Noise-cancelling headphones reduce the impact of peripheral noise on the basis of transmitting audio, making the use of headphones more high-quality. When buying headphones, first understand the performance and functions of the product, and choose a high-quality manufacturer.
