Objective

2

To explore the effects of cochlear implants (CI) with wireless listening system (hereinafter referred to as CI+FM) in outdoor teaching for preschool hearing-impaired children.

Methods

2

Under two environments (indoor short-distance and outdoor long-distance)

46 hearing-impaired children wearing two hearing assistance modes (CI+FM and CI alone) underwent name-calling response tests (at 2 m and 10 m) and Ling's five-sound detection tests (at 2 m

10 m

25 m

and 50 m). Test results were comparatively analyzed.

Results

2

At both indoor and outdoor short distances (2 m)

the name-calling response rates for both CI+FM and CI modes were 100.0%

with no significant difference (

P

=1.000). At outdoor long distance (10 m)

the name-calling response rates for CI+FM and CI modes were 100.0% and 80.4%

respectively

showing a significant difference (

P

=0.005). At 2 m

Ling's five-sound detection rates showed no significant difference between CI+FM and CI modes (

P

=1.000). At long distances (10 m

25 m

50 m)

detection rates for CI+FM mode were significantly higher than for CI mode (

P

<

0.001).

Conclusion

2

The cochlear implant with wireless listening system effectively improves long-distance speech detection rates in hearing-impaired children within a certain range and enhances listening outcomes during outdoor teaching activities.
