“…During the measurement, the microphone for the sound level meters was positioned approximately 1.5m above the floor and kept separate from any reflective surfaces to avoid interference caused by reflections (Meng et al, 2013). The results were compared with the data of the noise map calculation at the same location to ensure that the error is within 2dB(A) (See Table 7).…”

To improve the acoustic environment of residential blocks, noise mapping is employed in this study to analyze traffic noise distribution and the influence factors of four types of residential blocks in China. The study shows that high-rise small blocks have the highest average noise level (L avg ) for ground and building facades, followed by small low-rise blocks while modern residential blocks yield the lowest value. An analysis of the standard deviation (STD) of spatial statistical noise level (L n ) shows that the STD of the ground and building façade of two types of small blocks is higher than that of other blocks. The analysis of influence factors indicates that the lot area of residential block has significant negative correlation with ground and building facade average noise level (L avg ) , and street coverage ratio (SCR) has significant positive correlation with ground and building facade average noise level (L avg ). In low-rise and high-rise small blocks, ground space index (GSI) has significant negative correlation with ground and building facade average noise level (L avg ); street interface density (SID) has significant positive correlation with the STDs of ground and building facade noise. Floor space index (FSI) shows significant positive correlation with the STDs of ground and building facade noise in low-rise small blocks.

“…On acoustic comfort, interviewees answered on the following five-point Likert-type scale: 1, very uncomfortable; 2, uncomfortable; 3, neither comfortable nor uncomfortable; 4, comfortable; 5, very comfortable [57]. Before the formal investigation, the validity and reliability of the questionnaire were tested [58][59][60]. As previous studies indicated that users may not able to evaluate an acoustic environment accurately until around 15 min after they have entered it [61], the interviews were carried out about 20-30 min after diners entered the restaurant.…”
