TECHNICAL DESCRIPTION
Acoustic Shell for Symphony Orchestra and Choir
Acoustic Shell proper to large installations, can host large
Orchestras with one or two choirs. It is made up of two
side walls, one variable height and inclination back wall
and a system of upper ceiling panels, suspended from the
theatre lattices. The walls are made of well integrated
panels, arranged on the stage in variable configurations
and styles which optimize both the reflection/propagation
of the sound toward the audience and the reciprocal listening
among the musicians. Finally, they have two or more double
gate doors.
The walls and the ceiling panels are realized with a particular
plywood which have known sound reflecting and spreading
properties, certified in class 1 for fire resistance.
The single wood panels which make up the walls are fixed
to an integrated aluminium support frame which stiffens
them and controls the resonances. These are held up by telescopic
tie-rods fixed solidly on the stage via a direction guide
on the floor and they are connected and integrated between
one another by a tried and true theatrical system of ropes
for stage scenography.
The single panels which make up the ceiling, which also
has an integrated rigid frame, are connected to the "American"
girders (or to a special ring) with rapid link adjustable
steel cables which hold them in suspension. They are joined
together tightly by special PVC profiles.
Acoustic Shell for Chamber Orchestra or Soloist
Acoustic Shell for small/medium installations proper to
Chamber Music Orchestras or Soloists. It is made up of side
and back walls with projecting points and variable height.
The walls are made of integral panels between them, arranged
on the stage in variable configurations and styles which
optimize both the reflection/propagation of the sound toward
the audience and reciprocal listening among the musicians.
The walls are realized with a particular plywood with excellent
acoustical properties, certified in class 1 for fire resistance.
The wood panels which form the walls are made of two distinct
elements: one lower, vertical and one upper, inclined and
tilted forward, called jutting. The particular configuration
allows excellent acoustic results to be obtained even without
having to install upper ceiling panels, which in any case
can be provided where necessary. The double height wood
panels which form the walls are assemble on a single integrated
backstay in aluminium which stiffens them and controls the
resonances. They are held up by telescopic tie-rods fixed
to the stage.
