碩士 / 國立高雄師範大學 / 教育學類研究所 / 86 / Abstract The pruposes of the study were to investigate hearing
and communication
problems of workers with Noise Induced Hearing Loss(NIHL), to
discover the effect
of a self-designed Hearing Conservation Program(HCP)and to draw
administrative and
educational personnels'' attention to the issue of hearing
conservation for workers.
Subjects were 69 workers who had typical NIHL(V-typed)and
85 workers who had
precipitous-typed hearing loss. They worked in a steel company
in Kaohsiung cith.
Workers hearing threshold levels and their answers to
questionnaire of communicative
problems were analyzed and the effect of HCP was examed on 43 NIHL workers.
The results were as follows.
I. For workers with V-typed audiograms:
1.The hearing level at 4kHz in the better ear of those who
drank alcohol were
worse than those who didn''t drink. The predictability of the
hearing level at 4kHz in
the better ear based on alcohol drinking was 6.56%.
2.Those who self-evaluated their hearing as poor, felt their hearing was
getting worse, had tinnitus, wore ear-plugs more often, worked
in noisy areas for
less years, had more serious communicative problems. The predictability of
communicative problems based on these five items were 43.53%.
3.The greater the loss of threshold at 1kHz in the left ear and at 0.5kHz
in the right ear were, the more serious were the communicative
problems. The predictability
of the communicative problems with these three items were 10.46%.
II. For wirkers with precipitous-typed audiograms:
1.Those wiho self-evealuated their hearing as poor, had a
low level of education,
felt their hearing was getting worse, the predictability of the
threshold at 4kHz
with these three items were 11.47%.
2.those who wore ear-plugs less, were older, drank alcohol, had passive
attitudes toward ear-plugs wearing, smoked, the average of
thresholds at 0.5kHz,
1kHz and 2kHz were worse. The predictability of the average of
thresholds at 0.5kHz
1kHz and 2kHz with these five items were 31.65%.
3.Those who self-evaluated their hearing as poor, felt
their hearing was getting
worse, had tinnitus, self-evaluated their communicative ability
as poor, had more
serious communicative problems. The predictability of the
communicative problems
based on these four items were 44.1%
4.The greater the loss of threshold at 4kHz in the right
ear and at 4kHz, 8kHz
in the left ear, the more serious were the communicative
problems. The predictability
of the communicative problems with these three items were 10.46%.
III.About half of NIHL workers had moderate to severe degree of
difficulty in hearing
comprehension. About 10% of NIHL workers had moderate to severe
degree of troblesome
in communication. About 15% of NIHL workers had moderate to
severe degree problems
in communication.
IV.Workers with NIHL needed to improve their knowledge in HCP.
V. The HCP was effective.
The self-designed HCP was effective both in improving
workers'' knowledge and
in their attitudes toward HCP. They were satisfied with HCP
program and appreciated
the value of the HCP, realized that workers who worked in noisy areas needed to
participate in HCP, and they wore ear-plugs more willingly.
