MAX NEUHAUS, R. MURRAY SCHAFER, AND THE CHALLENGES OF NOISE

In this dissertation, I analyzed Max Neuhaus’s (1939-2009) and R. Murray Schafer’s (b. 1932) commentary and work regarding noise, its control, and its relationship with the environment from the 1960 to the 1980s. Both Neuhaus and Schafer as well as those more directly involved with noise abatement research and policy were responding to the challenges and possibilities that noise posed in the latter twentieth century. In this project, I delved into these substantial links and argued that responding to and engaging with noise abatement policies was a key impetus to much of their work, which scholarship has yet to critically examine. Inspired by the listening strategies that Neuhaus and Schafer set forth, I also considered ways in which music educators and social activists might approach sound, becoming aural advocates or activists when working in their communities. The works selected for analysis reflected contemporaneous studies held in the USA and Canada investigating the psychological and physiological impact of noise on humans, animals, and their landscape. Just as these investigations grew into the 1970s, new attention developed towards acoustic ecology and public sound art, both fields dealing with the relationship between sounds, living beings, and the environment. Neuhaus’s works analyzed include the Listen series (1966-76), his New York Times op-ed piece titled “BANG, BOOooom, ThumP, EEEK, tinkle (1974), and the Emergency Vehicle Siren Redesign project (1978-1989). These Neuhaus projects provided an alternative to the movement towards acoustic ecology put forward by his contemporary, Schafer. Analyses of Schafer and the World Soundscape Project’s (WSP) publications included Ear Cleaning (1967), The Book of Noise (1970), and A Survey of Community Noise Bylaws in Canada (1972). Featured were primary sources from the Max Neuhaus Papers (Columbia University Rare Book and Manuscript Library), newspaper reviews, and clippings. Also included were interviews with artists/associates of Neuhaus from his performance career (Phil Orenstein) and his Sirens project (Ray Gallon, Owen Greenspan, Herr Lugus, Julia Prospero, and Wolfgang Staehle) as well as Schafer\u27s fellow WSP collaborator, Hildegard Westerkamp

Real-time noise filtering with adaptive filters in heavy equipment soundscape

In this master’s thesis, adaptive filters are used to abate the engine noise of heavy equipment and the changes in the soundscape are studied. The main objective of this work is to enhance the sound quality of human speech and shouting. The results are evaluated both with subjective tests and computationally. The first method used in achieving the goal is the Butterworth band-pass-filter, which is designed to preserve the frequencies possibly containing human speech and filter the rest of the frequencies. The resulting signal of the Butterworth filter is filtered with the adaptive filter targeting the engine noise. In this study two different adaptive filters are used, the Wiener filter and NLMS filter, and their performance is compared. In addition to the method of implementation, these filters also differ in that the Wiener filter does not use a reference signal for adaptation, but the noise is estimated from the input signal itself, while the NLMS filter uses a microphone in the engine compartment as a reference signal. The filtering system developed in this study is implemented on a developing platform, which is designed to be used by the end user, in other words, the operator of the heavy equipment. This is the reason why the results of the subjective tests are in focus in this study. According to both objective and subjective evaluations in this study, the engine noise deteriorates considerably and the speech coming outside the vehicle is cleaner. In the thesis the results were evaluated both with Sandvik Pantera DPI series drilling machine and a large diesel engine car, Nissan Pathfinder. The subjective evaluation is compared with the signal-to-noise ratio and signal-distortion ratio, which both indicated that the enhancement was successful. Even though the test conditions were not optimal, the results show that the adaptive filters can be used efficiently to filter the engine noise in real-time

Advanced extravehicular activity systems requirements definition study. Phase 2: Extravehicular activity at a lunar base

The focus is on Extravehicular Activity (EVA) systems requirements definition for an advanced space mission: remote-from-main base EVA on the Moon. The lunar environment, biomedical considerations, appropriate hardware design criteria, hardware and interface requirements, and key technical issues for advanced lunar EVA were examined. Six remote EVA scenarios (three nominal operations and three contingency situations) were developed in considerable detail

Regulation number 61-7 emergency medical services

This regulation details the requirements for ACT 1118, amended in 1974. Its purpose is to establish guidelines for an EMS program, including licensing, certification, inspection, and training procedures. It also highlights the Emergency Medical Service Council and outlines its responsibilities. Additionally, the regulation grants the Department of Health and Environmental Control the authority to enforce these rules and regulations

The implementation of UHF radio communications and CCTV monitoring systems in a room and pillar metal/non-metal mine : final report

"This report describes the design and implementation of radio and closed-circuit television systems in the Black River room-and-pillar limestone mine near Butler, Pendleton County, Kentucky. Prior to designing the radio system, measurements of signal attenuation on 812 and 466 mhz were made in the slope tunnel and in the straight and level crosscuts in the mine. Two distributed antenna systems fed by two sets of base stations provide approximately 75 pct coverage of the mine. Passive reflectors were used for extending signals into intersecting crosscuts and two-way signal boosters will be used to extend signals to the perimeter and obstructed areas of the mine. Fourteen mine vehicles were equipped with mobile radios with digital identification, alarm, and status encoders. Fifteen portable transceivers also were used. Six closed-circuit television cameras provide surveillance of critical transfer points of the belt conveyor system, the loading dock at the base of the slope, and an ash disposal area in the mine. Two-way radio communication and closed-circuit television have saved considerable work hours, increased production, reduced maintenance costs, and enhanced safety." - NIOSHTIC-2NIOSHTIC no. 10002199198
