In complex noise environments, an accurate analysis of the soundscape is often not possible without calculating several different types of acoustic metrics. Collecting percentile levels, such as L10 or L90, in addition to the Leq often provides a more accurate description of the acoustic environment. This is especially evident in areas where a wide range of noise levels are present, such as healthcare spaces. In many situations, it is assumed that on average, the L90 is comparable to the Leq. However, recent research in healthcare facilities shows that the Leq is often closer to L33 or L10. Similarly, Leq in outdoor areas dominated by traffic noise has also been documented to be approximately equal to L33. The relation between Leq and percentile levels of hospital environments will be compared to those of several outdoor environments, such as areas dominated by noise from highways, trains, and amusement parks. This analysis will lead to a better understanding of the impulsive nature of noise in healthcare spaces.
