An Open Source Noise Calculation Toolkit for Acoustics
(2017)Many Acoustic Engineers today use custom spreadsheets or custom functions to perform their calculations to further enhance the speed and reliability of their calculations. This offers benefits over manually entering tables ... -
Comparison of ceiling absorption placement configurations in a corridor
(2017)It is generally acknowledged that speech related noise is a common distractor in many work environments, e.g., open-plan offices. There are many studies and some standards that address these noise related issues, but they ... -
Intra walker variability of footfall vibration and the effects of walkers’ mass and carrying loads
(2017)Excessive floor vibration in buildings can make occupants uneasy and many prediction methods of varying de% gree of sophistication have been developed over the years to assist engineers in the prediction of footfall ... -
An overview of structure-radiated noise and vibration assessment for elevated rail infrastructure
(2017)Elevated rail infrastructure has potential to cause structure-radiated noise and vibration concerns during rail op-erations to the neighbouring community. In this paper, an overview of a structure-radiated noise and vibration ... -
Development of a standardised test for comparing pool isolation systems
(2017)Pools in apartments and hotels are commonly isolated from the building structure to ensure noise and vibration from a pool is not transmitted to surrounding spaces. Currently no standardised test exists to compare the ... -
Building a university music facility in a reused printery building
(2017)In 2015 Western Sydney University embarked on a project to refit two existing buildings to create a new music precinct. The building housing the recording facilities previously accommodated the University's printery, ... -
Performance evaluation of a shock wave-based method for supersonic bullet trajectory estimation
(2017)The supersonic flight of a bullet generates a ballistic shock wave (SW). As the bullet is subjected to both drag and gravity, its speed decreases with the distance travelled and its trajectory is more or less curvilinear. ... -
Propagation of underwater noise from an offshore seismic survey in Australia to Antarctica: measurements and modelling
(2017)An offshore seismic survey was conducted over the western edge of the continental shelf in Bass Strait in 2006. Underwater noise from this survey was recorded on an autonomous sound recorder deployed in the Southern Ocean ... -
Predictors of noise exposure in construction workers
(2017)Construction workers are exposed to hazardous noise from a wide variety of tools and equipment. This study aims to determine the workplace tasks associated with being exposed to occupational construction noise above the ... -
Application of FAMPRADOP (“Far-range Analytical Model for the Pressure Radiated from a Driven Offshore Pile”) to the far-range cases of the COMPILE 2014 Workshop
(2017)The cases considered by the COMPILE 2014 workshop in Hamburg defined a pile (length 25 m), a shallow-water environment (depth 10 m), the pile’s vertical position in it, and a force waveform on the pile head. It also defined ... -
Metamaterial design for middle-low frequency elastic wave miti-gation
(2017)In the past two decades, meta-materials have drawn increasing attention from researchers due to their unique properties, including wave attenuation with potential application in acoustic engineering. A number of meta-material ... -
An equivalent fluid representation of a layered elastic seafloor for acoustic propagation modelling
(2017)Modelling range dependent sound propagation over layered elastic seafloors with high shear speeds has proved to be a difficult problem for many widely used under water acoustic sound propagation models. Recent research and ... -
NAVAL APPLICATIONS OF MARINE ACOUSTICS
(2017)Both communities have interests (or requirements) that can be described by the parameters of time and space. The science and technology of Marine Acoustics, dependent on specific investigators and their focus, is not ... -
Sound radiation from the open end of pipes and ducts in the presence of mean flow
(2017)The radiation of sound from the open end of pipes and ducts is a common problem in environmental noise control. Examples include radiation from ductwork in heating, ventilation and air-conditioning systems, noise ... -
Active control of sound transmission through a hole in a large thick wall
(2017)Holes in walls of enclosures or buildings are often the weak link in the chain of sound insulation. This paper in-troduces an analytical model to calculate the sound transmission from a baffled rectangular hole based on ... -
Classification of active sonar echoes using a one-class classification technique
(2017)A typical approach to data classification based on machine learning algorithms is binary classification. This in-volves the classifier to be trained using representative data sets provided from two object classes. In ... -
Setting noise objectives for outdoor events at the Sydney Opera House
(2017)Unwanted music from outdoor events is considered a form of noise pollution which presents a unique set of challenges for regulators when compared to other environmental noise sources. Unlike noise generated by sources such ... -
Determinants of annoyance from humming sound as indicator of low frequency noise.
(2017)The level of concern and health complaints related to low frequency noise (LFN) seems to be increasing, not only in the Netherlands, but also at international level. There is evidence suggesting an association between LFN ... -
Monte Carlo model of acoustic response from a bubble cloud
(2017)In various sonar applications it is important to model the acoustic response of a bubble cloud to a sonar pulse of different types. In a typical approximate approach, a bubble cloud is modelled as a set of point scatterers. ... -
Predicting and managing rolling noise emissions from trains on the Perth metro passenger rail network
(2017)This paper presents an investigation of rolling noise emissions from trains operating on the Perth electrified passenger network, as an outcome of the Public Transport Authority's strategic initiatives in noise management. ...
