This report explains the development of a sound measuring system for continuous monitoring of sound levels. Dedicated telephone lines are used for data transmission so that sound level data can be monitored at installations far from the area of concern. This allows the sound sensing equipment to be left unattended and thereby greatly reduces the manpower costs of operation. That predetermined data conditions can be detected when they occur and corrective action can be taken immediately at the data receiving installation further justifies the method used. Background information and general need for such a system are discussed. Growing public concern with noise is creating a demand for more and better sound measurement devices and for more control of unnecessary noises. For description, the system is divided into functional sections. The sections are described and design considerations are given in order of data flow starting with the sound sensing devise, or microphone, and ending with the warning system which alerts the operator when a predetermined signal level has been exceeded. Circuits to detect selected conditional of excess sound and to control the alarm to these conditions are included.

What would it mean to make space inspired by the sounds of a particular place. The sounds are natural and man-made heard on the site; the place is Virginia Polytechnic Institute and State University's campus. I designed a series of outdoor spaces that reflect sound, and provide a structure where people can add to the sounds of campus. This project creates space that facilitates acoustic activities of a university. The walls reflect and focus sound due to their material and geometry. Sound is treated as a building material; used to help form the spaces that are visibly bounded by concrete and plywood. Concrete walls and plywood floor will alter the acoustic activity on the site; the acoustic fabric will be constantly changing, providing unique moments for people to discover as they pass through the site. / Master of Architecture

Este trabalho tem como proposta discutir a restauração sonora de filmes no Brasil. Através de entrevistas realizadas com profissionais da área de som que já participaram de diversos projetos com este objetivo, da pesquisa de textos sobre o assunto e da experiência do seu autor nessa área, o texto busca oferecer um panorama acerca das questões técnicas e dos procedimentos de trabalho envolvidos nas etapas da restauração sonora, bem como um histórico de alguns dos trabalhos já realizados e das principais dificuldades encontradas pelos profissionais que atuam nesse campo. Como resultado, o presente trabalho busca apresentar as diferentes filosofias de trabalho que tendem a ser assumidas para o processo de restauração sonora e como cada escolha pode afetar a originalidade e o conceito da obra. Assim, mais do que na discussão teórica sobre a restauração, o viés desse trabalho incide na relação entre técnica e postura conceitual do restaurador, bem como no modo como essa relação afeta o resultado da restauração descrito pelas experiências práticas destes profissionais. / This work aims at discussing movie audio restoration in Brazil. By means of interviews with audio professionals who have previously worked on such projects, research on writings about the subject, and the author\'s own experience in the field of sound restoration, this work tries to offer a panorama of the technical questions and operating procedures involved in sound restoration. It also offers a history of previously performed work and expounds the main difficulties faced by professionals working in this area. As a result, this study presents the different work philosophies that are most commonly adopted during the sound restoration process, and how each choice can affect the originality and conception of the work. Thus, more than a theoretical discussion on restoration, this work concentrates on the relationship between the technique and the conceptual posture of the restorer, as well as the way this relationship influences the restoration results as described by these professionals practical experience.

Im Genehmigungsverfahren für den Bau hochliegender Schallquellen (z.B. Windenergieanlagen) muss der Nachweis geführt werden, dass von den Anlagen keine schädlichen Umwelteinwirkungen ausgehen. Es ist es daher notwendig, die Schallausbreitung derartiger Quellen grundsätzlich zu untersuchen. Eine Schwierigkeit stellt dabei die gekoppelte Wirkung von Temperatur-, Windgeschwindigkeits- und Windrichtungsprofil in Zusammenhang mit dem Bodeneinfluss auf die Schallausbreitung dar. Dieser zeitlich und räumlich variable Atmosphäreneinfluss wird insbesondere bei Langzeituntersuchungen der Schallimmission bisher nur unzureichend in den operationellen Modellen beschrieben. Das Ziel der Studie besteht deshalb darin, die gekoppelte Wirkung von Atmosphäre- und Boden-Einfluss auf die Schallausbreitung in einem Bereich bis zu 2 km Entfernung von der Schallquelle mit dem Modell SMART (Sound propagation model of the atmosphere using ray-tracing ) zu untersuchen. / The licensing procedure for the construction of high-placed sound sources (e.g. wind power stations) demands to proof that no (significant and) harmful impact on environment is outgoing from these systems. Therefore, it is necessary to analyse the sound propagation of such a kind of sources. In this context one central problem has to be managed: the coupled effect of temperature, wind speed and wind direction profiles combined with the influence of surface on sound propagation. The temporally and spatially variable influence of the atmosphere is only insufficiently described by the operational models, especially in relation to long-time investigations of sound immission. Consequently, the aim of this study was to investigate the coupled effect of atmospheric and surface influence on sound propagation up to distances of 2 km away from the sound source using the model SMART (Sound propagation model of the atmosphere using ray-tracing).

The purpose of the thesis is to investigate how sound creates distinct, cognitive and spatial entities, sound spaces, and to find out how sound spaces constitute forms of human interaction. A further aim is to establish concepts used when studying sound spaces, thus contributing to a Swedish terminology for describing and analysing sound and sound spaces.   The analysis follows a hermeneutic spiral, alternating between inductive and deductive methodology, between the individual and the general. Conclusions are transferred from Istanbul to a broader level; to people in general. Forms of representation are developed by composing an exposition of pictures, maps, graphs, notes and links to acoustic files, alongside the written account. The study is based on well-established music and acoustic terminology. Terms that are used in the thesis are explained in information boxes. Altogether, this constitutes an attempt to build a comprehensive cultural analytical vocabulary to describe in text what a sound space sounds like. The study shows how sound has much to tell about the lived life in a large city, here represented by sound spaces in Istanbul. Sound is greatly significant in people’s lives. Sound spaces can be regarded as arenas for communication between people and are included in a world of sound containing interaction and crucial information. By investigating and bringing attention to spaces of sound that are shaped by their users in such places as urban environments, insights are won concerning the significance of everyday life in the city environment. With emphasis on the importance of sound, the interconnection between the subjective and the objective world of sounds is studied, contributing to enhance the understanding of how the world functions through sounds. The sound spaces of Istanbul are the sounds of a metropolis, which means that the study not only portrays and analyses sound spaces in general, but stresses metropolis sound spaces, and conditions for listening, being heard and communicating in large cities.  The study contributes to bringing attention to and clarifying the knowledge that can be extracted by recognising the value of sound and listening in the research of cultural studies.
