Auditorium Overview The    Auditorium    space    types    are    the    areas    for    large    meetings,    presentations,    and performances.   Auditorium    space    type    facilities    may    include    assembly    halls,    exhibit halls,   auditoriums,   and   theaters.   It   also   may   include   features   as   sound   reinforcement systems,     audiovisual     systems     and     projection     screens,     food     service     facilities, proscenium stages with heights. Auditorium   spaces   are   designed   to   accommodate   large   audiences. As   such,   they   tend   to have   wide   spans   and   are   multiple-stories   high   in   order   to   accommodate   seating,   sight- line,    and    acoustical    requirements.    Raised    stage/dais    floors    and    special    lighting equipment   are   often   required   as   well.   Typical   features   of Auditorium   space   types   include the list of applicable design objectives elements as outlined below. Functional / Operational Sloped   Floors:   Sloped   floors,   with   level   terraces   for   each   row   of   seating,   help provide the proper sight-lines from the audience to the stage. Fixed   Seats:   Typically,   fixed   seats   with   tilting   upholstered   seat   and   back,   integral arm    and    tablet    arm    are    provided    with    articulated    back    for    maximum    occupant passage    space    between    rows.    The    seats    may    be    fully    upholstered    or    wood contoured   outer   back   and   seat   shells   with   wood   armrests   with   tablet   arm   option and aisle light option at row ends. Seat number/row letters should be put properly. Special   Lighting:   Dramatic   lighting   systems   include   front   lighting,   foot   lighting, spot    lights,    follow    spot    lights,    beam    lights,    and    flood    lights,    and    a    projection room/booth   with   manual   and   programmable   lighting   controls,   and   space   for   the spot   light   operator   space.   Lighting   systems   should   be   flexible   to   accommodate various   performance   venues   (e.g.,   lectures,   plays,   musical   performances,   etc.)   in the Auditorium. Occupancy:   Occupancy   Group   Classification   is Assembly A1   or A3   as   per   IBC,   with sprinkler    protected    construction,    and    GSA   Acoustical    Class   A    space    requiring special acoustical design. Productive Special    Acoustical    Design:    Quality    acoustical    characteristics    are    important    in Auditorium   spaces   so   that   performances   and   presentations   can   be   clearly   heard and    understood.    For    performance    spaces    and    general    presentation    spaces, recommended     noise     criteria     (NC)     rating     ranges     from     NC-20     to     NC-30; recommended   sound   transmission   class   (STC)   rating   ranges   from   STC   40   to   STC 50. Good   Sound   System   Design:   This   is   very   important   for   Auditoriums   and   needs   to be installed properly.   KASUGA ENTERPRISES-Auditorium Consultant in Mumbai India, Ravi Rele
