Diverse Linguistic Development in Prelingually Deaf Children with Cochlear Implants

Table 1

Preimplant unaided and aided pure-tone average audiometry. Postimplant pure-tone average and speech audiometry in the four implanted children.

	Participant 1	Participant 2	Participant 3	Participant 4
Unaided pure tone average (across 0.25 to 2.0 khz)	100 dB HL	100 dB HL	100 dB HL	105 dB HL
Hearing aid pure tone average (across 0.25 to 2.0 khz)	63 dB HL	65 dB HL	62 dB HL	71 dB HL
Age at cochlear implant	5.6 yrs	5.5 yrs	4.10 yrs	3.8 yrs
CI pure tone average (from 0.25 to 4.0 khz)	30 dB HL	25 dB HL	38 dB HL	30 dB HL
CI speech audiometry at 50 dB (% of words correctly understood)	40	90	70	25
