“…The highway is the main source of noise in the settlement areas. 16 Traffic noise is very dependent on several parameters, such as the traffic volume, the traffic flow typology, the vehicle typology, the road and pavement features, the speed, and interaction between tires and the road. 17 The Palembang-Indralayahighway is a cross-provincial thoroughfare where the volume of vehicles is constantly increasing.…”

Palembang – Indralaya highway is a cross-provincial road where motor vehicle activity is constant, causing noise and affecting settlements along the road. Constant exposure to the noise that exceeds quality standards (55 dB) stipulated in Environmental Ministerial Decree (KEP.48/MENLH/11/1996), can cause a variety of health problems, such as hearing loss and psychological disorders. Therefore, this study is conducted to determine the noise level along the Palembang-Indralaya road. This study used an observational approach through direct observations and measurements using the Mini InScienPro SQ-100 sound level meter. The noise level is measured at two locations, i.e., on the curb and in houses located along the highway. Based on the observations and measurements, the highest noise intensity was during the daytime (78.0 - 102.4 dB). The highest intensity of noise inside and outside the house are 74 and 90 dB, respectively. This is due to the high volume and activity of vehicles crossing the highway. The intensity of the noise received by the residents along the highway is above the quality standards, so as to handle the noise, trees need to be planted around the housing (barrier plants).

“…Traffic volume and noise level comparison between the roundabouts and intersection show that, lesser traffic noise was generated at roundabout due to low speed of vehicles passing around the central island [18]. On the contrary, 3 dB (A) higher noise level was observed at roundabout compared to cross-intersection, due to high acceleration of vehicles while leaving the junction [21]. This is due to the fact that, compared to vehicles travelling at constant speed, accelerating vehicles generates higher noise levels due to change in driving pattern.…”

“…The main objective of constructing rotaries and intersections is often to improve traffic f low and safety on roads. However, the negative upshot is often diversified in the driving pattern of the vehicles, such as speed, change in acceleration or deceleration due to which noise levels tend to increase [19]- [21]. Even though the primary objective of improving traffic flow by reducing the conflict points from a safety point of view is achieved with rotaries/roundabouts, the noise level at these intervenes of urban area will severely affect the people residing nearby as most of the road stretches are passing through residential and commercial zones, where continuous noise exposure can lead to cardiovascular health hazards in humans which is a serious consideration to be made to the core for reducing noise within the limits [22].…”

AbstractThis paper presents a study conducted at major rotaries for quantifying the traffic noise levels by considering the vehicle volume and their respective honking as governing parameters for heterogeneous traffic. Traffic volume and traffic noise data was collected using a digital video camera and a class 1 sound level meter, respectively. The traffic noise data was analysed using noise tools for identifying the noise level variation. The data collected was subjected to statistical analysis for light, medium and heavy vehicles, and their contribution towards noise levels is proven to be effective with the forthright fact that, heavy vehicles and their corresponding honking were majorly affecting the equivalent noise level compared to other vehicular proportion. An equivalent noise level [LAeq (dB)] rise of 2 to 6 dB (A) is solely caused by heavy vehicles, which is an important observation to be considered for traffic noise analysis at the rotaries. Based on the obtained results from one of the rotaries, noise prediction model is developed for estimating the LAeq (dB), which is able to predict the noise levels with good precision when validated with the data collected at second rotary intersection for different vehicle volumes.

“…It suggests that annoyance is a more complex experience, also related to other characteristics of noise or people. Among other interesting factors which have been already investigated are: surface material or vehicle speed [18], having a peaceful room with a quiet façade [19], noise spectrum [20], type of a crossroad [21], different street geometry [22], the presence of green areas [23], personality traits [24], or the number and loudness of noise events/pass-bys [25]. The latter case could be described as time structure and was also analyzed by Kaczmarek and Preis [26], as well as Wunderli [27] and Brink [28].…”

Purpose Road traffic noise is the most common source of noise in modern cities. The noise indicators used to manage noise do not take into account its temporal structure. However, in cities the traffic flow varies during the day, peaking due to congestion and more fluent periods. In this research we sought to analyze how people (giving answers on a numerical ICBEN scale) perceive noise stimuli with the same LAeqT values but different time structures (more/less noise events, different amplitude envelopes). Methods 31 people with normal hearing took part in an experiment conducted in an anechoic chamber. Participants listened to 18 different noise recordings and rated each of them using the numerical ICBEN scale regarding noise annoyance. Results The results showed that only sound level was a statistically significant factor. However, based on people’s remarks about noise, we can also say that the more intermittent the noise is, the more negative feelings it evokes in people. Conclusions Time structure does not have a significant influence on people’s judgments about noise annoyance. However, people tend to have a preference for a steady noise rather than an intermittent one.
