Fig. 1From: Measuring implanted patient response to tone pipsTypical electrical cochlear response (ECR) morphology. It is generated due to electrical stimulation delivered to the patient’s auditory nerve each time the CI process a tone pip of known frequency and intensity. The figure illustrates the ECR due to a 20 ms, 1518 Hz at 60 dBHL tone pip presented in sound field with patient using the device in everyday mode and positioned 0.60 m away from the sound sourceBack to article page
