Updating the who guidelines on community noise
The guidelines aim to eliminate or reduce exposure to these pollutants, and are targeted at public health professionals, specialists and authorities involved in the design of buildings and indoor materials and products.
They provide a scientific basis for legally enforceable standards.
Average sound levels always exceeded 45 d BA and for 50% of the time exceeded between 52 and 59 d BA in individual ICUs.
There was diurnal variation with values decreasing after evening handovers to an overnight average minimum of 51 d BA at 4 AM.
The most important means for avoiding adverse health effects is the prevention (or minimization) of persistent dampness and microbial growth on interior surfaces and in building structures.
