Comparedto video analytics, audio analytics offers several benefits, includingless expensive equipment and upkeep expenses. Additionally, the volume ofthe audio datastream is substantially lower than the video camera datastream,especially concerning real-time operating systems, which makes it lessdemanding of the data channel’s bandwidth needs. For instance, automaticlive video streaming from the site of an explosion and gunshot to the policeconsole using audio analytics technologies would be exceedingly helpful forurban surveillance. Technologies for audio analytics may also be used toanalyze video recordings and identify occurrences. This research proposeda deep learning model based on the combination of convolutional neuralnetwork (CNN) and recurrent neural network (RNN) known as the CNNRNNapproach. The proposed model focused on automatically identifyingpulse sounds that indicate critical situations in audio sources. The algorithm’saccuracy ranged from 95% to 81% when classifying noises from incidents,including gunshots, explosions, shattered glass, sirens, cries, and dog barking.The proposed approach can be applied to provide security for citizens in openand closed locations, like stadiums, underground areas, shopping malls, andother places.展开更多

In view of current sound environment features of old urban residential districts and different population groups' preferences for different sound elements, this paper proposed soundscape design methods to improve sound environment of old urban residential districts.展开更多

Thus, sounds coming from commercial activities are becoming much more multifarious, at the same time, more annoying. This is because of Taiwan’s special residence custom. In Taiwan, most people live in the residence commercial complex zoning, which means residents expose to the commercial activities noise in daily lives. In order to investigate residence commercial complex zoning sound environment from user’s point of view, there were 800 questionnaires handed round, and 273 questionnaires were replied. There are six evaluation factors in influencing molding commercial space sound environment. According to the users’ observation and experience, three factors play important roles in influencing users’ evaluation regarding sound environment design, including amenity(pleasant, comfortable or unpleasant, uncomfortable), vitality(active or inactive) , and atmosphere of warmth (warm or cold). In the regression analysis, amenity and volume(Leq) have a negative relationship(r=-0.558), which means volume is an important factor in commercial space sound environment molding. In the past, high volume amplifier system was applied extensively in commercial district to attract more crowds. However, amenity is declined under such noisy environment. It is a very important issue to study the trade off relationship between these two situations and improve noise problem in residence-commercial complex zoning.展开更多

The analysis, based on a wide range of measurements and statistical data,revealed the changes of the ambient noise resulting from city development. In conclusion, some fundamental measures for improving the acoustical environment were suggested, such as the division of cities into functional areas and the development of a well designed road network. In addition, the town planning, architecture and the implementation of appropriate regulations could also help to reduce noise levels was suggested as well.展开更多
