ARCHITECTURAL ACOUSTICS
CAN BE ABOUT ACHIEVING GOOD SPEECH INTELLIGIBILITY IN A THEATRE,
RESTAURANT OR RAILWAY STATION,
ENHANCING THE QUALITY OF MUSIC IN A CONCERT HALL
OR RECORDING STUDIO,
OR SUPPRESSING NOISE TO MAKE OFFICES AND HOMES MORE PRODUCTIVE
AND PLEASANT PLACES TO WORK AND LIVE IN.
ARCHITECTURAL ACOUSTIC DESIGN
IS USUALLY DONE BY ACOUSTIC CONSULTANTS
BUT WE HAVE TO KNOW ABOUT IT.

1. Are you looking to block sound or absorb echo?
2. What are the dimensions of and surfaces in your room?
3. What is the room used for, what types of sound(s) are you looking to
block/absorb?
(a high pitch-squeaky sound, voices, low frequency-bass type sound, all of
the above)
1. What are your ideas as to the best way to treat the room, where to put
product, or how to approach the situation?

Objek perancangan akustik
Tujuan dari perancangan akustik suatu ‘venue’, baik itu ‘indoor’ maupun ‘outdoor’,
semestinya menyertakan dan memperhitungkan juga ketiga karakteristik objektif
komponen utama akustik tersebut.
Pada umumnya, apapun perancangan akustik yang dilakukan, apakah itu perancangan
tata suara lengkap, tanpa memberikan ‘acoustics treatment’ pada ‘venue’ di luar
ruangan, maupun perancangan akustik ruangan, misalnya perancangan akustik ruang
‘home theatre’ atau studio rekaman, maka tujuan atau objektifnya adalah menghasilkan
medan suara yang optimal dan tepat yang dapat didengarkan oleh pendengarnya.
Medan suara yang didengarkan oleh pendengar ini tentunya memiliki karakteristik
yang ditentukan oleh besaran-besaran yang bersifat objektif yaitu karakteristik fisika
dari medan suara.

SOUNDPROOFING VS SOUND ABSORBING –WHAT’S THE DIFFERENCE?
Absorbing
Products that are designed and
intended to absorb echo within a
room are soft, light, fluffy products.
They will generally feel soft to the
touch. They are designed to soften
up the surfaces within a room and
reduce the echo in that space.
Blocking Noise
Products that are designed to
block sound from entering or
leaving a space are almost
always found inside the wall
construction. These products are
heavy, dense, cumbersome, or
designed to decouple the wall so
that one side of the wall doesn’t
have hard surface contact with
the either.
Echo...Echo..….Echo….….
The room is made out of
concrete and is the size of a
standard racquetball court –
20′ wide x 40′ long x 20′ tall.
The walls of this room are two-
feet thick. You clap your
hands in the room and the
echo seems to go on forever.
Let’s have some fun in here.

Screens can provide an acoustic or visual barrier, or often a combination of the two. We can use a combination of
plain and louvred panels to accommodate different requirements, and the general design of the screen is always
tailored to suit the project.
