Abstract:
The acoustic qualities of healthcare sound environments can have significant influences on care providers’ ability to conduct critical sound tasks. Healthcare professionals constantly listen to the aural cues (e.g., alarms) and make critical decisions based on them. This study aims to assess the reliability of an open-source acoustical simulation tool in rendering healthcare providers’ auditory experience to enable the development of effective healthcare sound environments. The Pachyderm is developed as an open-source acoustical modeling and simulation plug-in for the Rhinoceros 3D-modeling pl

Textile membranes are an architectural solution used for their maximal lightness, efficiency and adaptability. Unfortunately, once they reach their end-of-life phase, it is difficult to recover them. To be disposed of, they undergo very expensive and often difficult recycling processes. Their reuse as an acoustic treatment and reverberation control system is a solution to creating a light, economical and effective acoustic system that also solves the difficult end-of-life scenario. The membranes take on the role of acoustic diffusers, elements that, through their geometric conformation, can co

This thesis is focused on the calibration of the Acoustic Emission (AE) technique to detect and identify damage mechanisms in tool steels. The AE measurement procedure has been calibrated for two mechanical tests: fracture test (three-point bending test) and indentation test (spherical indentation). Fracture tests cause cracks due to tensile stress. The damage begins with the nucleation of cracks (cracking carbides and local plastic deformation) and afterwards, the cracks spread through the metallic matrix following the broken carbides.

AbstractSoundscapes have been likened to acoustic landscapes, encompassing all the acoustic features of an area. The sounds that make up a soundscape can be grouped according to their source into biophony (sounds from animals), geophony (sounds from atmospheric and geophysical events), and anthropophony (sounds from human activities). Natural soundscapes have changed over time because of human activities that generate sound, alter land-use patterns, remove animals from natural settings, and result in climate change. These human activities have direct and indirect effects on animal distribution

AbstractIn this work, an indirect approach based on acoustic emission signals is presented to predict progressive tool wear in peripheral milling operations. Measurements of flank wear and cutting forces are considered in order to assess the performance of the method. The acoustic emission is found to be sensitive to changes of tool condition and the evolution of the wear land. The latter provides experimental evidence to support the current knowledge on tool wear estimation towards the definition of tool-life criteria based on indirect process variables.

Abstract:
This interdisciplinaray work combines expertise in engineering and entomology in Israel and the US, to develop an acoustic trap for mate-seeking female medflies. Medflies are among the world's most economically harmful pests, and monitoring and control efforts cost about $800 million each year in Israel and the US. Efficient traps are vitally important tools for medfly quarantine and pest management activities; they are needed for early detection, for predicting dispersal patterns and for estimating medfly abundance within infested regions. Early detection facilitates rapid response to invasio

Abstract:
Halfwave's ART Scan technology is a proven method of pipeline inspection and has been engineered and configured to suit a variety of pipeline diameters. Until now the smallest pipeline ART Scan could inspect is 10" with a bespoke application specific design. The purpose of this feasibility study is to investigate to challenges involved in the miniaturization of ART Scan to suit pipeline diameters from 8" to 12". Through this study each element of the ART Scan tool design has been considered, from Mechanical design, Electronics design to the development of a new ART transducer.

Abstract:
After recent high profile pipeline incidents in the United States, the National Transportation Safety Board (NTSB) issued recommendations to review ILI technologies with respect to tool tolerance, probability of detection and probability of identi?cation, and to provide a model with detailed procedures for evaluating the e?ect of interacting corrosion and crack threats. Phase I of the PRCI project NDE-4E was initiated in 2013 to address the ?rst of these recommendations to the extent possible by mining existing historical operator data. The main goal of the project was to create a database of

Abstract:
Virtual acoustic environments (VAEs) are an excellent tool in hearing research, especially in the context of investigating spatial-hearing abilities. On the one hand, the development of VAEs requires a solid evaluation, which can be simplified by applying auditory models. On the other hand, VAE research provides data, which can support the further improvement of auditory models. Here, we describe how Bayesian inference can predict listeners' behavior when estimating the spatial direction of a static sound source presented in a VAE experiment. We show which components of the behavioral process

Abstract:
The ability for operators to make operational and maintenance decisions based on in-line inspection (ILI) data depends on the performance of ILI tools with respect to sizing and detection of crack and stress corrosion cracking (SCC) features. A series of previous Pipeline Research Council International, Inc. (PRCI) projects created a database of ILI tool and pipe excavation data that can be used to evaluate the detection and sizing capabilities of ultrasonic (UT) (NDE-4-E Phase 1, PR-244-133731) and electromagnetic acoustic (EMAT) (NDE-4-E Phase 2, PR-244-153719) ILI technologies.
