Abstract
This study focuses on monitoring hospital noise in the study areas of Parit Buntar
Hospital. The objectives of this study were to measure noise levels of indoor and outdoor of
the hospital, to identify the source of indoor and outdoor noise and to produce the outdoor noise
profile at the hospital. This study was conducted within two days representing holiday
(Thaipusam Festival) which is Monday for outdoor areas and weekday which is Tuesday for
indoor areas to measure the noise environment by using a sound level meter. The noise
measurement was collected in every 3 minutes with interval 1 second. The noise levels
measurement were monitored in the morning (0800-1030), afternoon (1200-1430), evening
(1600-1830) and night (2030-2300). The list of noise sources was recorded manually from the
observation together with time occurrence and speed gun for measuring traffic speed of various
type of vehicle on roads. Minimum noise level (Lmin), maximum noise level (Lmax), noise
level exceed 10% (L10), 50% (L50) and 90% (L90) were measured to assist in assessing the
existing noise level at a various pre-determined location. Results showed that the monitored
noise levels in term of average LAeq (mean) between 53.9 dB(A) to 56.1 dB(A) for outdoor
due to traffic flow, the number of vehicles influenced the reading of the noise to the surrounding
and generator from Mydin Mall while for indoor average LAeq (mean) between 51.8 dB(A) to
61.9 dB(A) for Ward Angerik, Ward Dahlia, Ward Mawar and Ward Melor due to staff
conversation, phone ringing, cough, scrap chair, radio, audio and ceiling fan also contributed
noise to the surrounding. About 90% and above the noise levels recorded were exceeded the
Maximum Permissible Sound Level by Receiving Land Use for Planning and New
Development by Department of Environmental (DOE) which is 50 dB(A) in the day time and
40 dB(A) in the night time.
