3. Speech Perception in Noise; Noise facing HA

Test set-up:

• Speech noise presented from a loudspeaker at 90º directly facing HA.  Noise presented at 60 dB C below the speech (i.e. + 10 dB signal-to-noise ratio).
• If the patient scores above 80% correct (ceiling effect) or below 20% correct (floor effect) at +10 dB signal-to-noise ratio, then an alternative signal-to-noise ratio should be used.  Record the signal-to-noise ratio.
• At least 20 sentences per test condition

Test Conditions:

• CI(1)
