The imbalance number of rapid vehicles with transportation facilities has become the problem. In Denpasar, Indonesia, the congestion during peak hours happens so often. Based on the department of transportation in Denpasar, Indonesia, the number of vehicle ownership in Bali is 4.1 million in condition with a ratio of one resident to one vehicle with the current population of Bali Province approximately 4.2 million. Our study aim to measure the air chemical parameters of CO, O3, SO2, NO2 and the physical parameters of the noise level. The research population is the atmosphere environment in the Denpasar City area. The research sample points were taken in the city center and the outskirts of Denpasar, with a total of 27 sample points. We employed impinge to get the airborne chemical gases and it is all analyzed with a spectrophotometer. We used a sound level meter to measure the ambient noise level. The data analysis was performed with free sample t test. The average ambient air chemistry obtained CO 517.34 µgr/Nm3, O3 0.17 µgr/Nm3, SO2 61.46 µgr/Nm3 and NO2 2.51 µgr/Nm3 and an average noise level 67.66 dBA. The number has found below the requirements Environmental Quality Standards and Environmental Damage Standard Criteria by Bali Governor. There is a difference in the mean parameters of CO, SO2, NO2 and ambient noise level in the downtown area. The average CO is 757.15 µgr/Nm3, SO2 67.60 µgr/Nm3, NO2 3.77 µgr/Nm3 and the noise level is 68.53 dBA with Denpasar outskirts mean CO 217.57 µgr/Nm3, SO2 53.79 µgr/Nm3, NO2 0.95 µgr/Nm3 and noise level 66.57 dBA. There is no difference in the average ambient O3 in the city center area with an average of 0.22 µgr/Nm3 with the outskirts of Denpasar an average of 0.11 µgr/Nm3.

AbstractThe present research was conducted to study the urbanization of Vadodara city and to monitor the ambient noise level in the industrial, commercial, residential and silence zones of the city. A settlement map created by unsupervised classification for the land use and land cover study of Vadodara city clearly shows the increasing pattern of urbanization in its central part, which may be the result of urban sprawl due to migration of people from the rural to the urban areas. The fluctuation in ambient noise level was recorded using an A-weighted sound level meter in all the four zones of Vadodara city for 3 h at regular intervals of 15 min on 3 consecutive days at the same time. The results showed the highest equivalent noise level of 93.7 dBA in the commercial zone followed by 85.5 dBA in the industrial zone, 73.2 dBA in silence zone, and 70.2 dBA in the residential zone. The values of noise level were high in all the zones of the city increasing remarkably over the prescribed limit given in the Noise Pollution (Control and Regulation) Rules, 2000. Continuous exposure to such high level of noise may lead to detrimental effect on people.

Areas that are considered human-friendly are green spaces. The existing urban parks are designed to fulfill the role of relaxation, recreation, and entertainment. However, in many cases, these are historic places, which at the time didn't have much of an impact on external factors. Sustainable development issues are related to the quality of life and the usage of the environment and its resources by present and future generations. Noise and noise protection is an issue that is part of sustainable development. The inadequate implementation of the principles of sustainable development and non-inclusion of noise can noticeably lead to negative effects now and in the future. The aim of the paper is to analyze the soundscapes of two Bydgoszcz parks located in the city center. The values of the equivalent sound level for these areas were obtained from the existing Bydgoszcz acoustic plan. Subsequently, the resulting distribution of noise was compared with the results of subjective perception of sounds by visitors. On this basis, conclusions can be drawn regarding the ways of shaping such areas while taking into account the perception of visitors.

Airline Flight

As the world shrinks and demands for quality performers precipitously increase around the globe, travel becomes an important part of the professional's life. The professional voice user may encounter many circumstances and situations over which he has little control and which may subject him to potential vocal irritation or injury. Airline travel is an aspect that, by and large, is uncontrollable but absolutely necessary for professional survival, yet it may have the potential for harm. The majority of airline traffic is carried by wide-bodied aircraft, mainly the Boeing 747 and 767, the Lockheed L1011, the McDonnell Douglas DC-10, and the European Airbus. Similar but smaller aircraft include the Boeing 707, 727, and 737 and the McDonnell Douglas DC-8 and DC-9. Basically, these aircraft appear to exhibit relatively similar in-flight environments, including ambient noise level, cabin temperature, pressurization, humidity, and ozone. Each of these factors will be discussed to clarify aspects of flight which have been taken for granted, about which there have been misconceptions, or which have not been sufficiently considered. As otolaryngologists it is incumbent on us to be familiar with the consequences of flight for those patients with actual or potential voice problems. A voice lost to professional endeavor may be more emotionally devastating than an ear or sinus impairment. Careful briefing of the patient who is a professional voice user has not been standard practice prior to airline flight but certainly should be strongly considered as a protective measure.
