5.4

From the silence-softest /a/ trials:

• Select a 1 second segment of softest /a/ and get intensity

5.5

Calculate SNR by subtracting the silence intensity from the softest /a/ intensity
(Softest /a/)dB – (silence)dB = SNR

Calculate it in the Redcap Connected Speech instrument.
Ideally SNR is between 20db and 40db.

If SNR is within 20dB-25dB, the session should not be completed. **(Look below at solutions)
