Noise can be emanated from different sources. Road traffic noise (RTN) is one of the noise sources that has an adverse impact on human beings, especially the patients in Medical Health Care Units (MHCUs). Also, it bothers the hospital staff and raises the medical error rates. In the present work, the building envelope (facades) of Dr. Plaza Capital Medical Health Care (PMHCU) at Badr University has been studied. The sound pressure on the facades at different heights was estimated by using MASdBmap as a simulation tool. Based on the results obtained and the acceptance range of sound at hospitals, the sound transmission class (STC) was calculated. Then, three scenarios of curtain walls were examined based on the typical module parameters. The reverberation time (RT60) at the receiving room was calculated for each scenario using Sabine's equations. (D2m,nT,w) results were compared with the required (STC) for each façade. The analysis showed that the third scenario (CS3) using a curtain wall section with double glazing, 4--2 mm glass, and a 30 mm air gap is the optimum solution. [ABSTRACT FROM AUTHOR] |
