The document provides details about an auditorium design project, including terminology used in auditoriums and case studies of two existing auditoriums. It discusses the Chettinad Health City Auditorium which uses geometric patterns on walls and ceilings to create a visually dynamic space. It also examines the M Auditorium in Mumbai which was designed based on simulations of sound travel through different spatial forms. Standards for auditorium design discussed include site selection, size and shape in relation to seating capacity, stage specifications, roof/ceiling and floor materials, and seating layout.

PRELIMINARY STUDY
An auditorium is a room built to enable an audience to hear Dow and
watch performances at venues such as theatres. For movie Douc theatres,
the number of auditoriums is expressed as the number of screens. It is a
multi use performance space that is intended for various performing arts
like dance, drama, music, opera, theatre, magic shows etc. It may include
theatre, auditorium.
1.2 Type of Auditorium
.Proscenium theatre
Auditorium with
audience only on the front sides.
An enclosures covered or open where people can assemble for watching
Performance. An auditorium is a room built to enable an audience to hear
and watch and performance at venues such as theatres.

1.3 TERM USED IN AUDITORIUM
PROSCENIUM:
A proscenium is the area of a theatre surrounding the stage
opening. A Proscenium arch is the over this area. A
proscenium plane divides the performer and spectators.
HOUSE :
It is the main seating area.
GANGWAYS:
A passage between two rows of seats. The minimum gangway
should be 1100 mm.
AISLE:
The walkway between each area, row of seat to permit ease of
passage, (>=45mm)
DROP STAGE:
A stage floor that moves vertically on an elevator usually so
that one set can quickly replace another.
TORMENTOR:
A stage or framed structure used directly behind the proscenium
at each side of the stage to screen the wings & sidelights rom
the audience.
APORN:
The part of the stage floor in front of curtain line.

ORCHESTRA PIT:
The space reserved for musicians usually in front.
BALCONY:
A gallery that projects over the main floor of a theatre.
WING:
The platform adjacent to the stage for keeping props.
BOX OFFICE:
Where tickets are sold.
CYCLORAMA:

2.1.1 Chettinad Health City Auditorium
The project brief entailed the fitting-out and interiors of an
auditorium facility for Chettinad Health city, to be used as part of the medical
institute. The auditorium facility has been designed to cater to a diverse
activities such as stage performances, lectures, seminars, projection of
recorded medical information web-casts & broadcasts and more.
Conventionally,
auditoriums are perceived as
simple, monolithic, box-like
structures lined with internal
acoustic paneling. The design
intent was to shift away from the
typical morphology in order to
create a more visually dynamic
space.

2.1 LITERATURE STUDY
2.1.1 Chettinad Health City Auditorium
Located in Chennai, a cosmopolitan city which serves as the
gateway to South India, the project was exploited to be used as an opportunity to
create an interior which would sym bolize the face of the city. The city is known
to have played a significant role in the establishment of South India’s historical
and cultural expansion and hence the design approach is illustrative of a
progressive stance and the project interior exemplifies the same.
To break away from the monotony of an unadorned
environment of typical auditoriums, contemporary forms were used as
insertions to create continuous surfaces which were conceived to be in the
form of lines and planes that extended from the floor, to the wall and
wrapped through the ceiling, thus visually connecting the three surfaces.
Hence, the entire structure with the ceilings, walls and the floor of the
auditorium gives a vision of being one whole surface.

2.1 LITERATURE STUDY
2.1.1 Chettinad Health City Auditorium
One enters the vast expanse of foyer spaces that are broken
through geometric patterns. A similar pattern is reflected on the ceiling in
multiple layers to endow the space with a sensation of enclosure and to reflect
the dynamism similar to that which is shaped by the ceiling of the auditorium.
The strong lines of the planes are illuminated by cove lighting
and recessed light fixtures ensure that the purity of the forms and materials is
accentuated, whilst enhancing visual drama within the space. The auditorium
was envisaged using a similar approach, using the three-dimensional
geometric pattern to run through fabric-mounted, acoustical wall and ceiling
panels, eventually creating a Three- dimensional envelope for the auditorium
space.

Wooden Slots devised as portals, were shaped as insertions within the wall to
house HVAC, Lighting, audio-visual equipments and Acoustic services. To
augment the randomness of the false ceiling, recesses clad in wood were used to
puncture the ceiling. Materiality and palette is restrained, in order to let the
continuity of the surfaces be perceived.

2.1.2 M - Auditorium
For the design of this 300 seat auditorium in Central Mumbai They
studied sound, the very element that the space has to engage with. On the premise
that the space is merely a container and that sound deserves primacy in hierarchy
of considerations, we simulated wave patterns within the given structural volume
to understand its effect as it travelled through.
With the use of parametric and computational design tools, they are
ran multiple form finding experiments and studied the effect of every iteration on
the sound carrying ability of the space.

2.1 LITERATURE STUDY
2.1.2 M - Auditorium
The goal was to ensure that the spatial form and materiality
working together should help achieve even sound quality in the space while
keeping reverberation factor low. From suspended tiles to open cells and
eventually a closed volume, the design evolved out of multiple simulations.
A contoured volume rendered in wood faced acoustical board
acts to engage sound in a way that it carries from the stage, right to the back
of the auditorium without perceptible drop in intensity. Contouring creates a
sculpted feel on the ceiling and the walls and an interesting sense of space
inside.

The neutral palette of wood is complemented by grey and orange
auditorium chairs laid out in an outsized ‘V’ echoing the client’s logo. Stretched
fabric forms within contours are backlit with dimmable LED lights controllable
over zones and these engage with the patrons in an interesting way for the
moments leading up to the actual show. This project exemplifies our process in
which design is allowed to evolve out of first principles and key factors of
consideration without presupposing an aesthetic sensibility.

BASIC STANDARDS OF AUDITORIUM DESIGN
1) Site selection
Depending on ambient noise level Background noise should
not be more than 40-45 dB
2) Size and Shape
in relation to the number of audience required to be seated.
Avg height-6 to 7.5 m, Fan shape is considered best, sidewalls shall not be
more than 100 degrees, Farthest seat shall not be more than 23 m with the
curtain line
3) Stage
Depends upon the type of Performance the hall is to cater for,
4) Roof and ceiling
False ceiling, Sound proof material Rear portion of ceiling is
treated with sound absorbing material
5) Floor
Successive seats have to be raised over preceding ones, so
that the listener head is about 12 cm above the path of sound, which would
pass over the head of the front person. Angle of elevation of the inclined
floor in auditorium should not exceed 8degrees 20 % of the seating area
should be allocated for lobby , Foyer
6) Seats
The angle subtended with the horizontal at the front most
observer Should not exceed 30 degrees Distance between the stage and front
row should be 3.6m-4.5m Width of seat-45- 56 cm Distance between seats
back to back- 85-106cm
7) Reverberation time :
Reverberation time is defined as the time it takes for an
impulse of sound in a room to decay 60 dB, or one millionth of the original
level. This value is affected by most everything in the room, including room
volume, absorption of room material oom Is, diffusion from surfaces, and
room temperature and pressure

8) Distribution of Acoustic Material
Those areas which cause objectionable sound reflection and
need to be treated with sound absorbents should be earmarked for
treatment with sound absorbing material. These areas are
(a) the rear wall,
(b) the balcony parapet,
(c)any areas which may reflect sound back to the stage,
(d) concave areas
9) Sound Absorbing Materials
In an average hall, most of the absorption is provided by the
audience. It is therefore, becomes desirable to introduce special
absorbers(such as wooden paneling) on ceilings and walls which will
provide the requisite amount of absorption so as to achieve optimum
reverberation-time.
