The Walt Disney Concert Hall in Los Angeles has excellent acoustics due to its design by architect Frank Gehry. Gehry created curvilinear exterior forms to capture the motion of music and Los Angeles. The interior forms are similarly organic. The large auditorium volume has vertical seating arranged intimately around a central stage to provide clear acoustics for unamplified performances, as confirmed through scale modeling and acoustic studies. Pipes on the hall's organ were specially curved to match the curved wooden interior and enhance the sound.

2. INTRODUCTION
• ACOUSTICS
• Acoustics is a term referring to the qualities that determine a
room’s ability to reflect sound waves in such a way as to
produce distinct hearing.
• What does acoustics mean in architecture?
• Architectural acoustics is the study of sound in homes and
other buildings and the design of those structures for
optimal acoustic performance, including control of sound
transmission throughout the building, maintaining conditions
for good speech intelligibility, and maintaining sound isolation
for speech privacy.

3. WALT DISNEY CONCERT HALL
 Location :-111 south grand avenue Los
Angeles, California, U.S.
 Owner :-Los Angeles Music Center
 Architect :-Frenk Gehry
 Built :-1999-2003
 Structural engineer :-Cosentini Associates

4. • For about thirteen years, Walt Disney Concert hall has been a unique locus for
music, arts and architecture. Since it opening in 2003 it has been one of the most
recognizable symbols of Los Angeles and also one of the best known concert halls
of the world.
• It has become widely well known for its unique architectural form and its excellent
acoustics.
• Capturing the motion of los Angeles, and representing musical movement, Gehry
created an exterior composed of curvilinear forms that seem to dance both on
above the site.
• The design represents the style of their creator, architects frank gehry, could be
considered a work of art in itself.
• The extravagance of its forms seems to defy any rules of harmony and symmetry.
INTRODUCTION

5. CONCEPT
• The building is essentially a shell which consist of a series of
interconnected volumes.
• Some form of orthogonal coated stone and other forms of organic
and surfaces covered with a corrugated metal skin of steel.
• The interior can be seen in the shape of hull of a boat.
• Capturing the motion of los Angeles, and representing musical
movement, Gehry created an exterior composed of curvilinear forms
that seem to dance both on above the site.
• The design represents the style of their creator, architects frank gehry,
could be considered a work of art in itself.
• The extravagance of its forms seems to defy any rules of harmony
and symmetry.

11. ACOUSTIC DESIGN ANALYSIS

12.  A 1:10 scale model was constructed in order to test and
study the acoustics of the auditorium.
 The frequency of the sounds used for testing was increased
in order to reduce wavelengths by a factor of ten.
 To expel the oxygen and water vapour that absorbs high-
frequency sound the model was filled with nitrogen.
 One of challenges Toyota faced was achieving full sound
coverage from an unamplified orchestra that had no volume
control.
 The vineyard design calls for terraced seating to surround
the orchestra allowing for more flat surfaces.
 This would increase the area for sound to be reflected-an
important feature for the success of an unamplified
orchestra.
HALL ACOUSTICS

13. STANDARDS
• Aisles are required on both side of every row of seats that has more than 10
seats.
• Steps within aisles must be the full width of the aisle, minimum aisle width 1
metre.
• It must be uniform in size (both the riser and going).
• Its Going shall be between 280mm and 355mm.
• The Risers shall be between 115mm and 190mm.
• Minimum seating clearance must be 300mm if the distance to an aisle is less
than 3.5 metres, i.e. 8 seats or 500mm if the distance to an aisle is more than 3.5
metres.
• For the rows of seating served by aisles or doorways at both ends there may be
no more than 100 seats per row and the minimum width of 12 inches clearance
between rows shall be increased by 3 inch for every additional seat beyond 14 in
a row, but the minimum clear width need not exceed 22 inches.

14. SUMMARY
 The beauty of this concert hall is the way Gehry was able to
remove himself from the typical form and capture the motion
of music, creating an exterior that seems to dance both on and
above the site
 . The interior then becomes very organic as one journeys
between and into these sculptural forms.
 The creation of one large volume auditorium with a center
stage and vertical seating allows the patrons to have an intimate
relationship with the orchestra.
 The calibration with Yasuhisa Toyota and many sophisticated
acoustic studies produced a space described as having
"acoustical clarity".
 An organ's wooden pipes are often unseen, but these are front
and center to connect it with the wood interior of the hall.
 The pipes on this organ were curved and bent, which had not
been done before.
