An Experimental-assessment of Human Exposure-levels to Aircraft Noise-hazards in the Neighbouring-environments of four Nigerian Airports

IOP Conference Series: Materials Science and Engineering, 2018

This paper reports a scientific-assessment of the exposure-levels of aircraft noise-hazards suffered by persons living/working within the neighbourhoods of four Airports [Ibadan, Benin-City, Warri and Owerri] in Nigeria. Physical measurements of selected aircraft and environmental noise parameters [Ambient Noise Level (ANL), Sound Pressure Level (SPL), Aircraft Takeoff Noise-level (ATNL) and Aircraft Landing Noise-level (ALNL)]; were carried-out using the integrated CR811C Noise meter, during one hundred and twenty (120) periodic noise sampling-surveys; performed [from January to December 2017] at thirty (30) randomly-selected study-locations, within the vicinity of each of these four(4) airports in accordance with the Method/Standard-procedures specified by the International Standards Organisation's (ISO) relevant standards-ISO 3891, ISO 1996-1 and ISO 1996-2. The results showed that: while SPL ranged from 103-115 () dB A , ANL ranged from 52.3-64.1 () dB A , the ATNL ranged from 69.6-87.7 () dB A , and ALNL ranged from 66.2-82.7 () dB A. Actually, these results are alarming, since they significantly exceed the WHO Standard Recommended Maximum Noise-levels of: 35 () dB A [Indoor], 55 () dB A [Outdoor] to prevent Speech-intelligibility, Noise-annoyance & Sleep-disturbance; and 90 () dB A [being the Permissible Noise level/limit for 8hour daytime safe human exposure]. These and the results of the Statistical analysis (Wilcoxon Sign Rank Test) carried-out, clearly prove the existence of a generally ignored, but yet dangerous problem of continuous human-exposure to excessively high-levels of Aircraft noise-hazards to which residents of Airports' neighborhoods are subjected.

Estimation of airport noise impacts on public health. A case study of İzmir Adnan Menderes Airport

Transportation Research Part D: Transport and Environment, 2015

The air transport industry is showing rapid growth in line with the call for meeting the requirements of a rising population. Noise mapping is more useful than surveys and measurements to estimate the effects of noise on public health. In this paper, noise levels for the day, evening and night time slices around _ Izmir Adnan Menderes Airport were calculated by use of the SoundPLAN 7.2 software according to the European Noise Directive, and the ''ECAC Doc. 29-Interim'' method was applied for the computation of the aircraft noise. Air traffic data of year 2012, technical information about the airport and geographical data including the layers of elevation, residential buildings, auxiliary buildings, hospitals and schools were used as the main inputs for the model developed in the study. The model was found to perform well for the areas closer to the airport. The results of the study suggested that the area at the north side of the airport, where the city center of _ Izmir is located, is more affected than other areas. The threshold value of 55 dB(A) was found to be exceeded in 0.3% of the land area covered by _ Izmir City center during the time slice ''day''. The results showed that about 2% of the resident population was exposed to noise levels of 55 dB(A) or higher during day-time in _ Izmir. In addition, it was understood that the number of people who are potentially exposed to high noise levels and threatened by several illness such as hypertension and sleep disturbances is significant in the surrounding area of the airport. It is thought to be important for airport operators to manage the airport capacity based on the flight schedules in order to control the noise exposure level around the airport.

A Review of Non-Acoustic Measures to Handle Community Response to Noise around Airports

Current Pollution Reports, 2017

It seems obvious that the noise levels in local communities surrounding airports influences the level of acceptance of an airport. What is not so evident is the effect of nonacoustic factors that increase the societal rejection, like the lack of sensitivity and empathy from the authorities and airport managers, the lack of trust in them, the lack of information and transparency, the perception of being excluded from the decision making and so on. Complementary to the traditional strategies based on the reduction of noise exposure, a community engagement and involvement approach brings new possibilities to manage noise around airports, trying to exploit the non-acoustic factors that have negatively affected the community response. Building trust among the stakeholders is a key factor in this strategy, and it must be based on a long-term, honest, and transparent two-way communication. In the last decade, the huge growth of the information and communication technologies has opened new opportunities that the aviation organizations and stakeholders are starting to explore in depth trying to reduce the degree of rejection of the airport, which may compromise the utilization of existing and future infrastructure. In this review, we make a short introduction on aircraft noise health effects, to focus annoyance and the influence that non-acoustic factors on it. Then, we describe the basis of community engagement as a parallel approach to mitigate noise issues around airports, setting the focus on the noise metrics and the involvement techniques that must be implemented to engage the community.

Assessment of Acoustical Performance of Residential Buildings for Sustainable Liveability and Satisfaction in Awka, Anambra State Nigeria

Asian Journal of Environment & Ecology, 2020

This study assessed the acoustical performance of residential buildings in Awka, Anambra State to determine the level of satisfactions of the occupants. The study surveyed the residential buildings and distributed questionnaires to the users and occupiers of different classes of residential buildings. The results of the survey were analysed using Means Satisfaction Index (MSI) and Relative Performance Index (RPI) to assess the level of satisfaction of the occupants of the buildings and the acoustical performance of the buildings respectively based on 12 selected acoustic performance criteria. It further used Pearson Product Moment Correlation to establish the relationship between occupants' level of satisfaction and acoustic performance of the buildings. The study found that the overall acoustic performance of the buildings was grossly poor and unsatisfactory with average RPI of 0.35. It also found that the residents were very dissatisfied with Original Research Article Okoye et al.; AJEE, 12(3): 25-37, 2020; Article no.AJEE.56378 26 the acoustic performance of the buildings in which they live (average MSI =1.74). The study further found that there was significant positive relationship between the occupants' level of satisfaction and acoustic performance of the buildings with a Coefficient Correlation (r) of 0.875 and a computed t-test value of 5.708 which is greater than the critical t-value (2.228) tested at 5% significance level. The Coefficient of Determination (R 2 = 0.7567) then suggested that about 75.69% level of satisfaction of the occupants of the residential buildings in Awka could be triggered by the acoustic performance of the buildings in which they live. On this evidence, the study craves for the enforcement of the provisions of the National Building Code as regards to sound control in buildings. In addition, there is need for adoption of different strategies for improving acoustics performance of buildings such as absorption, mechanical decoupling, mechanical damping, blocking, covering, etc., so as to promote good acoustic practices that would improve sustainable performance of our buildings and decline the resulting consequences of sounds in our residential buildings.

DEVELOPMENT OF A METHODOLOGY FOR EVALUATION AND COMMUNICATION OF AIRCRAFT NOISE IMPACTS AROUND AIRPORTS

Noise-related land-use restrictions are included in Brazilian regulations since the beginning of the 1980s. These restrictions are applied in areas subjected to aircraft noise levels higher than compatibility criterion defined by the responsible authorities. However, noise-related conflicts remain common not only in Brazilian airports, and there are reactions from communities located in areas considered compatible by the regulations. Additionally, the current metric for aircraft noise evaluation in Brazil (Ldn - Day-Night Average Sound Level) is not easily understood by the general public, which jeopardizes the communication between airports and the communities affected by the noise. Given this scenario, the objective of this work is to propose a new methodology for aircraft noise evaluation, based on the application of weights on the number of noise events, with the objective of providing a good correlation with perceived annoyance, together with an increased ease of understanding to people without technical knowledge on acoustics. To validate this methodology, a survey was realized at the surrounding areas of the São Paulo-Guarulhos International Airport (GRU), in Brazil, with the use of online forms and advertisements published in social networks. The 547 responses obtained were used to evaluate the annoyance level caused by aircraft noise on the communities living on the surroundings of this airport. The results show that the proposed Weighted Number Above (WNA) and Verbal Number-Above (VNA) metrics are similar to the Ldn in terms of correlation with the reported annoyance, and has the additional advantage of the improved ease of understanding. The analysis also show that the current aircraft noise compatibility criteria are associated with annoyance levels higher than the ones foreseen by the applicable requirements, which confirms the need to consider community engagement aspects on the land-use definitions around airports, and not only the subjective aspects of noise acceptability.

Assessing Health Effects and Soundscape Analysis as New Mitigation Actions Concerning the Aircraft Noise Impact in Small- and Middle-Size Urban Areas in Greece

Environments

In 2013 and 2014, two main International Airports in Greece were evaluated through the European directive on noise environment 2002/49/EC: “Nikos Kazantzakis” International Airport of Heraklion Crete and “Ioannis—Kapodistrias” International Airport in Corfu, both located in highly touristic areas of Greece. Acoustic measurement’s campaign, environmental noise mapping simulations and population exposure to noise were implemented in order to produce a complete Strategic Noise Map. Correlated to this acoustic approach, a comprehensive interview campaign and a detailed soundscape analysis were also conducted in both airports’ adjacent areas (Alikarnassos district in Heraklion and the peninsula of Canoni in Corfu City) in order to understand the impact of aircraft movements on both local residents and tourists, and analyze the perception of the soundscapes. A similar evaluation was also executed in order to assess possible health effects by using the WHO’s DALY’s (Disability Adjusted Lif...

[Health impact assessment of airport noise on people living nearby six Italian airports]

Epidemiologia e prevenzione

aircraft noise has been associated with several health effects. Because of the great success of low-cost flights, small airports have been turned into international airports thus exposing nearby residents to an increase in noise levels and potential disturbances and health disorders. to estimate the exposure levels and evaluate the health impact of aircraft noise on residents nearby six airports in Italy (Rome: Ciampino; Milan: Linate and Malpensa; Pisa; Turin; Venice) focusing on hypertension, acute myocardial infarction (AMI), annoyance and sleep disturbances. residents in the local Municipalities considered at 31.12.2010 were included in the study and their addresses were geocoded. Aircraft noise exposure in 2011 was defined using the Integrated Noise Model linked to each participant's address. Lden (<55, 55-60, 61-65, 65-70 dB), Lnight, Leq (day and night) were calculated. Available exposure-response relationships were used to estimate the number of additional cases of hy...

Sound environmental impact resulting from the operation of aircraft at Santos Dumont Airport – Rio de Janeiro

Seven Editora eBooks, 2023

The operation of aircraft produces negative environmental externalities, such as air pollution and aeronautical noise that impacts the areas near airport sites, becoming a major source of conflicts between communities and airport operators. Noise discomfort from exposure to airborne noise affects health, quality of life and sleep. Thus, it is important to conduct research that seeks to evaluate the impact of aeronautical noise in the surroundings of airports. Thus, in the present work the sound impact caused by aeronautical noise in areas surrounding Santos Dumont airport (SBRJ) in the State of Rio de Janeiro was evaluated. The methodology was based on simulations of noise curves in the acoustic metric DNL (day-night level) using the INM 7.0d software. The input data required for the simulations were provided by INFRAERO for the year 2016. With the noise curves, acoustic maps were elaborated with the aid of the QGIS 2.18 software. The population exposed to air noise in different noise curves was also determined. In addition, a comparison was made between the methodologies currently used in Brazil and in the European Community to determine the percentage of people who were bothered (%I) and highly bothered (%AI) in the different noise curves. The results indicate that the percentage of disturbed in each noise curve is small when related to the number of inhabitants per neighborhood and it is concluded that for a better evaluation of the impact of aeronautical noise, RBAC 161 (2013) can be complemented with the calculation of the exposed population with its percentages of bothered and highly bothered people.

Noise mitigation action plan of Pisa civil and military airport and its effects on people exposure

Applied Acoustics, 2014

The ''Galileo Galilei'' airport is a civil and military airport quite close to central Pisa. Although the airport brings benefits in terms of tourism and different types of income, the air traffic growth exacerbates the exposition to aircraft noise. This could significantly affect public health. To this day, a small number of studies takes into account the standard indicators of Europe by considering noise emission data for military aircrafts. We estimated the noise impact produced by the airport and we evaluated the related exposed population by using the Integrated Noise Model (INM). The noise power levels of both commercial and military flights have been considered as an input to the model. Predicted levels were validated by means of a noise-monitoring network. A new tracking system (AirNav Radar) that captures Automatic Identification System (AIS) signals emitted by each aircraft has been used to emulate takeoff and landing procedures. This improves the accuracy of the input to the model. We simulated noise maps for present and future scenarios, including those following the application of noise reduction measures. For each situation, we also estimated the exposure of the population and the percentages of highly annoyed and highly sleep disturbed people. We show the utility of AIS data and their specific elaboration to draw up noise abatement measures in order to reduce the noise impact on population and allow the airport development.
