Abstract:
The objective
s
of the research are
t
o
identify
the
noise sources
and
noise level
exposure
inside C130H aircraft
’s
hangar
;
to
produce nois
e mapp
ing
;
to identify hearing status of C
130H aircraft
maintenance crews
(MC)
;
and suggesting the noise
control measure that can be applied.
A field
survey on noise level by using
a
digital s
ound
level m
eter
and producin
g noise
mapping
.
A
h
earing test
ing
among
63
MC
was
carried out in
Institute of Aviation Me
dicine
,
Royal Malaysian Air
Force (
RMAF
)
.
Reviewing the literature and
a
nalyzing some control measure
s
to be taken.
Hearing test result
shown 41.2% of the MC
are having hearing impairment. The highest
noise level
at the central of the hanga
r is 92.2 dB
A
(
day
-
time) and 94.2 dBA (night
-
time) when there is a C130H aircraft starting its engine
at
50 meter
s
from the centr
al of the
hanga
r, 95.3 dBA (day
-
time) and 97.3 dBA (night
-
time) when there is a C130H a
ircraft Engine Ground Run
at 150 meter
s
fr
om the centra
l
of the hanga
r. Besides,
Auxiliary Power Unit
is producing the highest nois
e level which is 125.7 dBA
(day
-
time) and 127.7 dBA (night
-
time)
.
The application of Personal Protective Equipment
(PPE)
is the very likely control
measure to be taken while engin
eering control is ve
ry costly but
can be considered.
Since
noise
is
recognized as
a
hazard,
hearing protection as
PPE
will not be the ultimate solution as a control measure. Hence, the Engineering Control must be
identified and studied to be implemented
as an ultimate solution
to
control the noise hazard in long term duration.
