Signal-to-noise ratio
As noise ratio (formerly also evaluated Eigenstörspannungsabstand) refers to the difference between the reference sound pressure level of 94 dB (corresponding to an absolute sound pressure of 1 Pascal ) and the equivalent noise . In contrast to the equivalent noise level, a lower value here means more noise from the microphone and thus less modulation capability .
