Abstract:
Objective - （ ）
To explore the influence on the diagnosis of occupational noise induced deafness ONID using three
， Methods
versions of diagnostic criteria in 2002 2007 and 2014. A total of 1 766 workers who asked for ONID diagnosis
were selected as the research subjects using judgment sampling method. The results of pure tone audiometry were collected.
GBZ 49-2002Diagnostic Criteria of Occupational Noise-inducedHearing Loss（
The ONID was diagnosed using hereinafter referred to as
GBZ 49-2002），GBZ 49-2007Diagnostic Criteria of Occupational Noise-induced Deafness（ GBZ 49-2007）
hereinafter referred to as
GBZ 49-2014 Diagnostic of Occupational Noise-induced Deafness（ GBZ 49-2014），
and hereinafter referred to as and the
Results - - ， -
diagnostic results were compared. Compared with GBZ 49 2002 and GBZ 49 2007 diagnosis with GBZ 49 2014 had
（ vs ， vs ， P ）， （ vs ，
a higher rate of ONID 57.9% 66.0% 44.8% 66.0% both <0.01 and had a higher rate of mild ONID 47.3% 54.6%
vs ， P ） - -
36.0% 54.6% both <0.01 . The diagnostic rate for ONID using GBZ 492014 was higher than those using GBZ 49 2002 and
- （ P ）Conclusion -
GBZ 49 2007 in each age groups all <0.01 . GBZ 49 2014 improved the diagnostic rate of ONID compared
- -
with GBZ 49 2002 and GBZ 49 2007. The reason is related to the inclusion of 4 000 Hz hearing threshold with a weight of 0.1
-
as the diagnostic hearing threshold and the use of a new age and gender correction method in GBZ 49 2014.
