Prefabricated elements are being used for both exterior and interior walls, for partitions, floors, and suspended ceilings. The acoustics of any Auditorium will be considerably affected by a series of seemingly purely architectural considerations with regard to room shape, room proportions, layout of enclosures, dimensions and distribution of exposed structural elements, surface irregularities, fixtures, seating layout and capacity decorations, etc. The design of an acoustically efficient sound insulating enclosure will require equally special attention on the part of the designer.

Contemporary environmental control can create a complex, artificial environment in buildings, that will meet all the physical, physiological and psychological demands of the occupants. Thus, Sound Control, constituting a branch in the environmental control of buildings, can create an artificial sonic environment in which: The elimination of noise plays an important role in the room acoustical design of Auditoria; similarly, room acoustical problems are involved in the noise control of rooms.
The main factors which have made architectural acoustics a contributing participant in the environmental control of buildings. An incredible number of Auditoria i. The large sizes and capacities of many of these Auditoria have created room acoustical problems which definitely could not have been resolved a few decades ago.
In addition, the contemporary trend in architectural design practice of using plain, uninterrupted, hard i. In the structural and constructional field there is a continuously and rapidly increasing use of light-weight building materials and constructions.
Prefabricated elements are being used for both exterior and interior walls, for partitions, floors, and suspended ceilings.
Furthermore there is a growing demand for the flexibility and movability of partitions. All these elements lack the most important feature of an efficient sound insulating enclosure, i. This trend advocates that spaces in a building, instead of being separated from one another, should be rather integrated into visually undivided, large units without enclosures, continuing through open screens, grilles, space dividers, glazed barriers and curtain walls.
Even though this design concept generally creates pleasant interiors, it must be noted that the desire for open plans and undivided interior spaces conflicts with the exclusion of unwanted, penetrating noises and brings about noise control problems.
In the mechanical field the buildings are becoming increasingly mechanized; many components of the heating, ventilating and air conditioning systems fans, diffusers, compressors, cooling towers, etc. A contemporary office building is, in fact, entirely interwoven with a most comprehensive network of noise and vibration transmitting ducts, shafts, cables, conduits, wiring, etc. In addition to these interior mechanical noises new exterior noise sources are coming into existence, originating from the existing and new industries and from transportation jets, trucks, etc.
The exclusion or reasonable reduction of these interior and exterior noises constitutes a serious acoustical problem. The increasing demand for various Auditoria all over the world involves not only quantitative but also qualitative requirements.
No longer will an audience or a professional critic excuse the erection of an Auditorium having any serious acoustical defect. Large multi-purpose Auditoria are today utilized mainly due to box-office policy - for a multitude of purposes; such as, lectures, political rallies, panel discussions, recitals, stage presentations, concerts, etc.
