A Prima Donna on PC: Creative Labs Audigy 2

Audigy 2: Input/ Output Quality, Continued

The second test is of noise and interference levels, and measures in particular where the card's background noise is located and its sensitivity to interference from the computing environment: power supply, transformers and monitors.

Related to the above test, the dynamic range test gauges the level of noise generated in the presence of a sound signal, in this instance, a sine wave (1 kHz at -60 dB) at card input.
