Storing SNR for Speech testing
Word and Sentence Recognition tests can be performed in noise. The Signal to Noise Ratio can be stored with the data
regardless of whether the noise comes from the recording or is generated in the audiometer.
You can enter an SNR manually or set it to be calculated automatically based on the difference between the Stimulus and
the noise channel levels.
•
Manual:
is useful when signal and noise are mixed together in the speech recording.
•
Automatic:
is useful when you mix speech and noise from the two audiometer channels.
