ACOUSTICS:
"Acoustics" is a science of sound, which deals with origin, propagation and auditory sensation of sound, and also with design & construction of different building units to set optimum conditions for producing &listening speech, music, etc.
While our forefathers lived in relative tranquility, we are subjected to an incredible increase in the sources of noise and noise intensity both inside & outside our buildings, often with serious and harmful effects. At the same time, it has become an accepted practice to replace the conventionally thick and heavy building construction with thin, light, prefabricated, sometimes even movable building elements. There is also a growing demand for considerably improved hearing conditions. The knowledge of this science is essential for proper functioning of theaters, auditoriums, hospitals, conference halls, etc. also buildings are becoming increasingly mechanized. Use of A.C., work machines, appliances like: vacuum cleaners, typewriters, etc., noise pattern of building has increased, leading to greater need of noise control.
All these elements have contributed to make " ARCHITECTURAL ACCOUSTICS " an essential discipline in the control of interior & exterior environment.
AUDITORIUMS:
An auditorium includes any room intended for listening to music, including theaters, churches, music halls, classrooms, and meeting halls. The design of various types of auditoriums has become a complex problem in contemporary times, because in addition to itsvarious, sometimes conflicting, aesthetics, functional, technical, artistic and economical requirements, an auditorium often has to accommodate an imprecedentedly large audience. These are nowadays being used as multipurpose rooms in almost every field, stating from a small school to official buildings.
Hearing conditions in any auditorium are considerably affected by purely architectural considerations like - shape, dimensions and volume, layout of boundary surfaces, seating arrangements, audience capacity, surface treatment and materials used for interior-decoration. Seeing to the increasing use of auditoriums in present scenario, the study of acoustical concepts in "AUDITORIUM DESIGN" is a necessity.
