2. What is Performing art and cultural
centre?
•A multi-use performance space that is intended for
use by various types of the performing arts, including
dance, music and theatre. The intended multiple use
of performing arts centers in this sense differentiates
them from single-purpose concert halls.
•A cluster of performance spaces, usually but not
always under one roof, each possibly designed for a
specific purpose such as symphonic music or
chamber music or theatre, but multi-purpose as a
whole

4. Based on auditorium capacity of 800.

6. PRINCIPLE OF DESIGN
The horizontal angle to the center line at which
objects onstage, upstage of the curtain line, cease to
bear the intended relationship to other objects
onstage and to the background is approximately 60 .
SIGHT LINES

7. SEATING
Occupants of all seats are visually related to the performance when the
seats are oriented toward the stage . This necessitates curving the
rows of seats . The center of curvature is located on the center line of the
auditorium approximately the depth of the house behind
The angle subtended with the horizontal at
the front-most observer by the high object
should not exceed 30 degrees . Minimum
distance of front seats should be determined
by the highest point required to be seen on
the stage by about 750 cm or more.

8. Aisles
All rows are widely spaced and serve as transverse aisles
for purposes of seeing,
radial aisle are best, with
curved aisles only
slightly less efficient

14. Reverberation Time
The reverberant sound in an auditorium
dies away with time as the sound energy
is absorbed by multiple interactions with
the surfaces of the room. .
Reverberation time is defined as the time for the
sound to die away to a level 60 decibels or
(1/1,000,000) below its original level.
