Noise Impact

Investigation of the factors affecting individual response to noise provides an improved basis for the selection and implementation of noise impact reduction policies. This investigation is necessary because the cause and effect relationship between the level of noise exposure and noise response is confounded by personal and situational variables. Examination of the effects of these variables on response to road traffic noise with the use of data collected at residential sites in Southern Ontario suggests the following points for residential planning decisions. Arguments for taking no action to reduce noise impact are not supported. The sex, age, and socioeconomic compositions of residential areas are not important considerations for implementing measures to reduce noise impact. Life-style characteristics of residents on the other hand do affect response to noise. Methods to reduce noise must be effective indoors and outdoors to have a significant effect on attitudes: air conditioning alone is inadequate. Noise barriers appear to be more effective for improving attitudes than their noise reduction properties would suggest.

The noise levels inside metro units are considered a significant problem that makes passengers suffer from severe damage, especially for those who use the metro periodically. This research evaluates the acoustic environment inside the metro car and studies factors affecting the noise levels inside metro units and developing models for estimate noise in the metro unit while moving between stations. Greater Cairo Metro (GCM) Line 1 has been selected as a case study. A sound level meter was used to measure the equivalent sound level in dBA and evaluate the noise inside metro units. The results indicate that the noise levels are unacceptable compared with the international noise exposure standards. The highest measured noise level inside metro units is 91.2 dBA. These unacceptable noise levels led to more investigation of factors that may affect noise levels inside metro units. Other data have been collected, such as the speed of the train and the track alignment details. The results showed that the noise increases with the increase of the train speed until the speed reaches a specific value, then it decreases depending on the maintenance status and the train type. In addition, the noise levels through curved underground tracks are higher than the levels along straight surface tracks by 18 dB(A). Doi: 10.28991/cej-2021-03091674 Full Text: PDF

Abstract Metro has become one of the most used means among public transit due to its advantages such as mass transit capacity, safety, fast speed, and comfort. Despite its benefits, workers and passengers ride the metro daily, and they are continuously being exposed to a high level of noise. Noise exposure has been related to various health-related issues. This paper presents an evaluation of the acoustic environment at the station’s platform and studies factors affecting the platform’s noise levels. Greater Cairo Metro Line 1, 2, and 3 have been selected as a case study. The result indicates that noise levels are unacceptable compared with the international standards of noise exposure as the highest measured noise level at station platforms was 93.93 dB(A). Regarding the rolling stocks type, the L Aeq was different from one type to another, with a range of 2.28 to 6.5 dB(A). The L Aeq on the underground platforms station was 11 dB(A) higher than on the surface stations regarding the station type. For underground stations, the L Aeq on curved platforms higher than the straight platforms when a train arrived, stop and go from the station with a range of 2.7 to 4.9 dB(A). Regarding the station platform dimension, the L Aeq on the underground platforms with a 5 m width is higher than the one with a 3 m width by 3 dB(A).

The issues surrounding marine mammals and noise cannot be managed effectively without an understanding of the effects of that noise on individual mammals and their populations. In the spring of 2003 the National Research Council released Ocean Noise and Marine Mammals, a report that reviewed sources of ocean noise (natural and anthropogenic), the effects of noise on marine mammals, patterns and long-term trends in ocean noise, and included recommendations intended to improve understanding of the sources and impacts of anthropogenic marine noise. This paper provides a brief summary of observed effects of ocean noise on marine mammals and the factors that can change the response of the animal to the noise exposure. It introduces the reader to short- and long-term behavior changes that have been observed in marine mammals in response to ocean noise, and discusses future directions for marine mammal research.

We are on the cusp of a revolution in the aviation sector, driven by the significant progress in electric power and battery technologies, and autonomous systems. Several industry leaders and governmental agencies are currently investigating the use of Unmanned Aerial Vehicles (UAVs), or “drones” as commonly known, for an ever-growing number of applications—from blue light services to parcel delivery and urban mobility. Undoubtedly, the operation of UAVs will lead to noise exposure, which has the potential to become a significant public health issue. This paper first describes the main acoustic and operational characteristics of UAVs, as an unconventional noise source compared to conventional civil aircraft. Gaps in the literature and the regulations on the noise metrics and acceptable noise levels are identified and discussed. The state-of-the-art evidence on human response to aircraft and other environmental noise sources is reviewed and its application for UAVs discussed. A methodological framework is proposed for building psychoacoustic knowledge, to inform systems and operations development to limit the noise impact on communities.
