Signal/ Noise Ratio
The second test concerns the noise and interference level. This measures the location of the background noise produced by the card and indicates the card's sensitivity to various types of interference in the computing environment, such as power supplies, step-down motors, or computer monitors. The result was -67 dB, which is more or less average, and well below that produced by such cards as DMX 6Fire 24/96 or Audigy.
