The document discusses the importance of acoustics in conference rooms, emphasizing the need for proper design and sound treatment to enhance the meeting experience. It highlights common acoustic defects such as reverberation, echo, dead spots, and external noise, along with solutions like using absorptive materials and sound insulation. Additionally, it touches on the relationship between interior design and the functionality of conference spaces.

1. Acoustic
Confrence Room

2. Introduction of Acoustic
Acoustics is a branch of physics that study the
sound, acoustics concerned with the production,
control, transmission, reception, and effects of
soun
A conference hall, conference room, or meeting
room is a room where serious business happens
where your employees come up with innovative
ideas.

3. It is commonly found at large hotels and
convention centers though many other
establishments, including even hospitals, have
one.Such a room should have best of facilities
and convenience so that the meeting is
conducted smoothly and turns out fruitful

4. What is Confrence room
A conference hall, conference room, or
meetingroom is a room provided for singular events
such as business conferences and meetings. It is
commonly found at large hotels and convention
centers though many other establishments, including
even hospitals, have one.

5. Relation between Confrence room &
interior Designing
A well designed conference room with both
modern and classic touch. The chairs are ultra
modern with adjustable seat heights and trendy
look while the large table is made of quality wood.
To avoid an uneasy and cluttered atmosphere, the
room is served with plenty of free space. Large
floor sized windows let in ample amount of natural
light and gives a panoramic view of the
skyscrapers making meetings less stressful.

7. Acoustic Treatments
• We use acoustical absorbing materials on the walls.
• We add treatment on the ceiling above the conference
room table.
• If there is a drop tile ceiling with an open plenum cavity, we
have plenum rated ceiling barrier and return silencers to
reduce noise from other rooms and mechanical equipment
above.
• Acoustical door seal kits (ADA approved) can be placed
around your doors to seal out leakage, around the door.

8. List of Acoustical Defacts
• Reverbration
• Formations of echo
• Dead Spot
• Exterior Noise

9. Reverbration
• Reverberation is the persistence of sound in the
enclosed space , after the source of sound has
stopped.
• Reverberant sound is the reflected sound , as a
result of improper absorption.
• Reverberation may results in confusion with the
sound created next.

10. Formation of Echo
Not all sound that hits matter is absorbed. Some of
it is reflected. That means sound bounces off the
solid matter the way a tennis ball bounces off a wall.
Sound reflected back to its source is an echo.

11. Dead Spot
• This defect is the out come of formation of sound foci.
• Because of high concentration of reflected sound at sound
foci , there is deficiency of related sound at some other
points.
• These spots are known as dead spots where sound
intensity is so low that it is insufficient for hearing.
• This defect can be removed by suitably placing diffusers
and reflectors.
• Right proportions of internal spaces.

12. Extarnal Noise
• External noises from vehicles , traffic engines , factories ,
machines etc. may enter the hall either through the
openings or even through walls and other structural
elements having improper sound insulation. 
• This defect can be removed by proper planning of the hall
with respect to its surroundings and by proper sound
insulation of external walls

13. Acoustical Matieral
• Wall Panelling
• Floor Tile
• Ceiling Tile
• Curtains
• Carpet or Rug
