In 1986, the OECD produced “Fighting Noise: Strengthening Noise Abatement Policies” [1] and, less than a decade later, “Fighting Noise in the 1990s ” [2]. More recently, the Australian Academy of Sciences used a similar title [3] – all dealing with the management of environmental noise. These titles clearly signaled resolve to tackle the issues of environmental noise, including the focus of thi...
In this paper, we present a dynamic model modified with emission permit banking and pollution abatement, and investigate the effect of emission permit banking and pollution abatement on the production–inventory strategy of the firm. After introducing emission permit banking and pollution abatement, the cost function consists of the inventory holding and production costs, the cost of investment ...
In recent years, accompanied by economic growth, air transportation in Vietnam has rapidly risen with the introduction of many new airlines. This situation led to an increase aircraft movement frequency flying and out airports raised concerns about effects increased noise exposure levels on public health natural environment vicinity airports. authority also issued several documents regulate est...
The lower emissions Brenner Corridor project is carried out with the aim of creating a concept ‘lower corridor’ (LEC) for A22 motorway by implementing and validating set policies having goal to provide clear environmental benefits in terms air quality, climate protection noise abatement, i.e. dynamic road capacity management, speed limits management integrated traffic management.
Sound levels in animal shelters regularly exceed 100 dB. Noise is a physical stressor on animals that can lead to behavioral, physiological, and anatomical responses. There are currently no policies regulating noise levels in dog kennels. The objective of this study was to evaluate the noise levels dogs are exposed to in an animal shelter on a continuous basis and to determine the need, if any,...
A noise abatement method using an eigen function in conjunction with optimizer (Genetic Algorithm) under a space-constrain situation is proposed this study concerning high order wave propagation effect. An used to describe acoustical field and shorten the model four-pole transfer matrix form. The system’s estimates Transmission Loss (TL) for silencers by multiplying individual matrices.
OBJECTIVES Growing concern over the costs, environmental impact and safety of tobacco product litter (TPL) has prompted states and cities to undertake a variety of policy initiatives, of which litter abatement fees are part. The present work describes a framework and methodology for calculating TPL costs and abatement fees. METHODS Abatement is associated with four categories of costs: (1) me...
Limited information is available on the perceptions of stakeholders concerning the health co-benefits of greenhouse gas (GHG) emission reductions. The purpose of this study was to investigate the perceptions of urban residents on the health co-benefits involving GHG abatement and related influencing factors in three cities in China. Beijing, Ningbo and Guangzhou were selected for this survey. P...
The Environmental Noise Directive expects residents to be actively involved in localising and selecting noise abatement interventions during the noise action planning process. Its intervention impact is meant to be homogeneous across population groups. Against the background of social heterogeneity and environmental disparities, however, the impact of noise action planning on exposure to traffi...
Internal friction and ultrasonic attenuation peaks associated with diffusionless phase transformations in alloys, such as thermoelastic martensites and others, were reviewed. They were discussed from the stand point of (1) Understanding the mechanism of the phase transformations and (2) Developing new alloy materials of high damping capacity for application to noise and vibration abatement. Pha...
