Auditory Cortical Maturation in a Child with Cochlear Implant: Analysis of Electrophysiological and Behavioral Measures

Table 1

Hearing thresholds in free field of the child with hearing loss with the electronic device.

Length of stimulation	Intensity/frequencies
	250 Hz	500 Hz	1000 Hz	2000 Hz	4000 Hz	Média
	(dBHL)	(dBHL)	(dBHL)	(dBHL)	(dBHL)	(dBHL)
Preactivation (with HA)	75	95	NT	NT	NT	85
3 months of CI use	55	65	50	70	NT	60
9 months of CI use	45	50	40	55	70	52
18 months of CI use	45	40	30	30	45	38

Note. HA: hearing aid; CI: cochlear implant; NT: not tested.
