Two potentially critical food courts were selected from a group of twelve of such eating establishments, and sound pressure levels (SPLs) were measured and analysed with regard to acoustic quality. Initial measurements of background noise with the food courts almost empty revealed high SPLs in such places. Measurements taken with varied number of users showed an increase in SPLs in accordance to the cocktail party effect, ending up in values of 75 dBA and 81 dBA for each food court. Design aspects of the courts were discussed in order to improve the acoustical quality.
