Hospital is a place that should be free of acoustic
problems. According to previous researches, these acoustic
problems are responsible for 20.9% - 26.2% of the ICU patient’s
recovery process. A research based on soundscape of a hospital
was done through objective, subjective and simulation methods.
The result has shown that the most perceived loud sound is from
the ventilator at 4000 Hz with loudness level of 60 phon. The L90
score is between 55-59 dBA. The Leq ranged between 50.78-67.49
dBA at the left ear and 60.07-76.55 at the right ear from the first
receiver position. From the second measuring point, L10 score is
around 52.08-72.19 dBA at the left ear and 61.91-78.94 at the right
ear. This value indicates that the noise level in the ICU is high
enough, and caused discomfort for human hearing. Installation of
panels on ceiling at the nurse ward can reduce the intensity level
up to 3 dBA. Meanwhile, relocation of nurse ward can reduce up
to 4 dBA.
