9. ACOUSTIC ELEMENTS
The diffusers found in Bentley Auditorium
are the random pattern wood laths diffuser
seen on the side of the walls. The diffusers
consist of two elements which comprise of
absorbers and reflectors that trigger sound
diffusion effect. The highlighted area
displays the diffusers present in the
auditorium.

11. ACOUSTIC ELEMENTS
The reflectors are the catchy-eye panels
located on top of the ceiling. With its huge
size shows its strong characteristics of giving
the best reflection in the auditorium.
SOUND REFLECTIVE PANEL

12. ACOUSTIC ELEMENTS
Fiberglass panels for sound absorption
requirements are utilized.
Sound waves travel through the air and
strike the wall reducing panels,
fiberglass fibers vibrate, increasing
friction among fibers.
These vibrations reaches a point quickly
where friction is created for sound
energy to kinetic energy conversion.
Kinetic energy can’t be contained, it
dissipates quickly, leaving no sound
waves.
SOUND ABSORBER PANEL

SOUND ABSORBER PANEL

14. SOUND REFLECTION
The floor carpet surface,
wood panels on wall and
aluminums panels
attached ceiling reflect
almost all incident sound
energy striking them.
Concave-shaped
aluminums panels on the
ceiling form a reflective
surface having one focus
point which concentrate
the sound towards one
direction.

15. SOUND REFLECTION
CEILING REFLECTOR

16. SOUND REFLECTION
While carpet floor reflect
sound from direct
speaker towards the
front row. Partially
wooden panels act as
reflector to reflect the
sound towards the center
of the audience from
early reflection.

17. SOUND DIFFUSION
The design in Bentley auditorium help even diffusion of sound coming from the
stage and speaker, through its use of aluminum sound reflective ceiling with
concave side facing the interior therefore each of the seating zone from front to
back can relatively receive the same sound quality and equal sound intensity.

18. SOUND ABSORPTION
Soundproofing panels will boost the audience’s experience by improving sound
clarity in an auditorium.

19. DIRECT AND INDIRECT SOUND PATH
Direct sound travels directly from the source to the listener without striking any of
the surfaces of the room which contributes to sensations of loudness, clarity, and
localization. It will generally decrease as it moves further from the sound source.

20. DEFECTS
● Not completely sound proof
from the external noise.
● Front part of auditorium
hall is a huge curtain glass
panels.
● Exterior noise will be able
to penetrate into the
auditorium hall.
● More obvious as there is a
construction work going on
at the opposite of the
auditorium.
EXTERNAL NOISE FROM CURTAIN GLASS

21. DEFECTS
● Noise from foyer open area
can be heard from interior.
● Poor insulation of closed
doors.
● Solution is to add seals, for
example flexible material
like Neoprene. So that,
when the door is shut the
seal should be in line that
compress against the clean
surface.
POOR AIR TIGHT CONNECTION
AFTER AMENDMENTS

22. DEFECTS
The air vents is on top of the
ceiling hiding behind the
aluminums panels producing
whooshing of air, creates noise
and make it difficult to focus
at a certain time when the
room is quiet.
An annoying whooshing sound
from the vents outlet are
usually result of small openings
and tight grillwork that restrict
the airflow from the aluminums
panel.
