“I think there is beauty in everything. What ‘normal’ people would perceive
as ugly, I can usually see something of beauty in it.”
Astrology adalah sebuah pseudosains (ilmu semu) yang meyakini adanya hubungan khusus antara
peristiwa ruang angkasa (rasi bintang) dengan karakteristik dan nasib orang melalui praktek dan
metodologi yang tidak dapat dibuktikan secara keilmuan (psikologi, sosial,fisika,matematika).

Ruang Besar
P x L x T = 28 x 18 x 11 meter
Loudspeakers = 34 - 20,000 Hz
𝑓 𝑠 = 2000

𝑓 𝑠 = 36 𝐻𝑧
Studi Kasus 1
Suara Ucap Choir Musik
BEFORE TREATMENT
Suara Ucap Choir Musik
AFTER TREATMENT
Ruang Kecil
(sebelum optimasi)
PxLxT = 6 x 5 x 3 meter
Loudspeakers = 34 - 20,000 Hz
Modal Freq (1,0,0) = 343 / 6 meter = 57 Hertz
= 343 /34 = 10 meter

Ruang Musik Kecil
(sebelum optimasi)
PxLxT = 6 x 4 x 3 meter
Loudspeakers = 34 - 20,000 Hz
(1,0,0) = 57 Hz
Modes Frequency:
(1,0,0) 6 meter = 57 Hz

Sebelum Optimasi
PxLxT = 6 x 5 x 3meter
Setelah Optimasi
PxLxT = 5.6 x 4.4 x 2.7 meter
