The enormous increase of noise sources inside and outside our buildings, the simultaneous shift from heavy, traditional building constructions to thin, light-weight, moveable and prefabricated building elements, in conjunction with the growing demand for improved hearing conditions in Auditoria, have made architectural acoustics an essential component in the environmental control of buildings. Architectural acoustics, in both the fields of scientific research and practical application, has progressed further in the past few decades than during all preceding time, and consequently the amount of pertinent literature has reached an unprecedented high. It seemed to be worthy, therefore, to prepare an annotated bibliography on architectural acoustics for the assistance of those involved in architectural design problems, i.e., the architect, the engineer (mechanical and structural), the town planner, the builder, and the student of architecture and architectural acoustics.

Industrial estates deal with a very specialized use of land. The 20th century - and especially the post-war period. - has been a period of rapid expansion in all fields of urban growth and change. To accomodate the new growth (and in many instances to encourage new growth) various concepts and new methods of land organization have evolved to facilitate these pressures of rapid expansion. Among these are the shopping centre, the neighbourhood and community unit, the civic centre, the new plaza offices complex, segregated vehicular and pedestrian traffic, and among others the planned industrial estate.

The patterns of land subdivision form an essential element in the analysis of an urban area. In this essay an attempt is made to evaluate the importance of these patterns for urban growth on the Island of Montréal. The approach is an historical one, since the understanding of past patterns aids in our comprehension of the present. Thus in Part One the historical background to land granting procedures is examined, firstly in the Province of Québec, and then for the Island of Montréal. The cadastral divisions of the Island are discussed in Chapter Three, and a classification of the long lot systems is proposed. Part Two traces in greater detail the subsequent subdivision of the long lots for urban purposes.

The multipurpose hall is, by design, a compromise, designed to provide reasonable hearing conditions for a multiplicity of instrumental and vocal performances, without favoring or overly impairing any particular type of performance. Redpath Hall possesses a relatively long reverberation time, decidedly beneficial for the appreciation of some musical performances, such as organ recitals, chamber music, choral performances, string quartet, etc., but at the same time, noticeably detrimental for other performances; those instruments that excell with a long reverberation time, tend to mask other instruments, resulting in a definite orchestral imbalance, particularly noticeable in remote seats; quick passages of solo instruments are blurred; the spoken word is not intelligible.

Since the Industrial Revolution, the world has witnessed an utterly fantastic phenomenon of urban expansion hitherto unparalled. The establishment of large centres of population followed as a logical result of industrialization, but the speed at which they have outgrown their boundaries to mature into colossal masses of people and buildings is something unique to modern time. In North America, the rapidity of urbanization has accentuated urban problems which can be remedied only with the help of proper town planning. [...]

The value and usefulness or any block or space depends largely on its degree of accessibility. Without the ability to enter, leave, or move within it freely, space is of no value at all, no matter how rich in resource. A modern city may be looked upon as a communications net made up or roads, paths, highways, rails and wires. Its prosperity and rate of growth are roughly in proportion to the capacity of its circulation system. Without an efficient system or circulation, a city would soon lose its function. [...]

All experience combines the esthetic, visual experience with other 1evels of experience -- from the pbilosophical 1evel to the practical leve1 of how to find one's way around. Thus, I have considered a broad range of information relating to the clustering of skyscrapers. [...]

The desire to obtain a perfect physical environment and a more satisfying way of life is typical of Western Civilization, since it possesses dynamic force and incorporates economic strife for progress. The Central Area of a city is generally considered as the focal point of both communal and commercial life. It is in this Central Area where the greatest concentration of human activities from all parts of the Metropolis exist. [...]

Actually, the architect has been a climatologist much longer than being an expert or the other disciplines above. Very rarely does one see mention made of this role of the architect. Little training in this line is given the university student. This, therefore, is the object of this thesis: To acquaint architects and architectural students, particularly those in the Montreal area, with the demands and phenomena of the large and small scale climate, known respectively as the macroclimate and microclimate; and to inform them how to apply this knowledge to the design and orientation of buildings and towns. It is not the object to discuss the use of different materials, and their weathering qualities, except in a general sense. [...]

The planning of this study started with the author's personal observations from available reading material that in industry, some problems appear to be persistent. For instance: (a) rapid market and technological changes constantly tend to render many manufacturing plants economically and technically obsolete. [...]
