5.2.3 Sleep Disturbance
The Planning for Noise Control Guideline (Department of Environment and Science, Qld Government 2004)
specifies maximum noise levels for sleep disturbance based on research by the World Health Organization
(WHO).
The guideline recommends that maximum instantaneous internal noise levels in sleeping areas should not
exceed approximately 45 dB(A) more than 10 to 15 times per night. The corresponding external maximum
noise levels (LAmax), which should protect at least 90% of the population (i.e. a probability of only 10%
awakenings) are presented in Table 11. These levels differ according to window types and whether windows
are open or closed.
