The Effect of the Sound Level Parameter on the Acoustic Performance in Shopping Centers

The study focused on the objective measurement method of the sound level parameter, the geometrical formation, the observation of some acoustic properties, and their effectiveness for the atrium space in the Baghdad and Babylon shopping malls. In this study, a measurement of the sound level parameter was carried out to evaluate their acoustic performance and compare them with the standard standards required to be achieved in such buildings. The measurement process was conducted using a portable device SL-4112P that measures the sound level parameter SPL (A) and at a point on each floor around the atrium in both shopping centres for three minutes for each floor. The duration was determined according to previous studies. The measurement results of the average sound level values for both commercial centres showed an increase in the average
