The Discovery 925 also takes advantage of Plantronics’ new AudioIQ digital noise cancellation, which adjusts noise levels on both sides of the call, rather than merely the outgoing audio. For instance, in a noisy bar, the Discovery 925 will not only cut background noise by 7 to 8 decibels (about 50 percent) for listeners on the other end, it will also detect the noisy conditions and automatically boost volume level, quality and clarity with Digital Signal Processing (DSP) technology.
