Nama warna untuk berbagai jenis suara yang berasal dari analogi yang longgar antara spektrum

frekuensi gelombang suara hadir dalam suara (seperti yang ditunjukkan dalam diagram biru) danspektrum frekuensi setara dengan gelombang cahaya.. Artinya, jika pola gelombang suara "noise

biru" diterjemahkan ke dalam gelombang cahaya, cahaya yang dihasilkan akan menjadi biru, dan

seterusnya.

White noise

White noise Spektrum daya datar.

(Sumbu frekuensi logaritmik)White noise adalah sinyal (atau proses), dinamakan dengan analogi cahaya putih , dengan rata

spektrum frekuensi . Dengan kata lain, sinyal yang sama memiliki kekuatan dalam setiap band

diberikan bandwith ( kepadatan daya spektral ).. Misalnya, dengan sinyal audio kebisingan putih,rentang frekuensi antara 40 Hz dan 60 Hz mengandung jumlah yang sama sebagai kekuatan

suara berkisar antara 4000 Hz dan 4020 Hz memiliki.

Pink noise

. Kebisingan merah spektrum.). Kepadatan daya jatuh pada 10 dB / dekade (-3 dB / oktaf).

Spektrum frekuensi pink noise linear dalam ruang logaritmik, tetapi memiliki kekuatan setaradalam band yang lebar proporsional.[1][2]Ini berarti bahwa pink noise akan memiliki kekuatan

setara dalam rentang frekuensi dari 40 sampai 60 Hz seperti dalam Band 4000-6000 Hz. Karena

manusia mendengar dalam ruang yang proporsional, di mana dua kali lipat frekuensi (satu oktaf)dianggap sama terlepas dari frekuensi aktual (40-60 Hz didengar sebagai interval yang sama dan

jarak sebagai 4000-6000 Hz), setiap oktaf berisi jumlah energi yang sama dan kebisingan

sehingga pink sering digunakan sebagai sinyal referensi dalam teknik audio . Para kerapatan

daya , dibandingkan dengan kebisingan putih, menurun sebesar 3 dB per oktaf(kerapatansebanding dengan 1 /f). Karena ada jumlah tak terbatas band logaritma pada kedua frekuensi

rendah (DC) dan ujung frekuensi tinggi dari spektrum, setiap spektrum energi yang terbatas

harus memiliki kurang energi daripada pink noise pada kedua ujungnya. Pink noise adalahkerapatan daya spektral-satunya hukum yang memiliki properti ini: semua spektrum hukum

kekuatan curam yang terbatas jika terintegrasi ke ujung frekuensi tinggi, dan semua menyanjung

hukum kekuatan spektrum yang terbatas jika terintegrasi ke DC, frekuensi rendah batas.

Brown(ian) noise

Brown spektrum (-6 dB / oktaf)

Di bidang yang mengadopsi definisi yang tepat, "kebisingan merah" terminologi, juga disebut

kebisingan Brown atau kebisingan Brown , biasanya akan merujuk pada kepadatan kekuatan

yang berkurang 6 dB per oktaf dengan meningkatnya frekuensi (kerapatan sebanding dengan 1 /fselama rentang frekuensi yang tidak termasukDC (dalam pengertian umum, tidak termasuk

komponen konstan, atau nilai nol frekuensi). Di daerah di mana terminologi yang digunakan

secara longgar, "kebisingan merah" dapat merujuk ke sistem dimana densitas daya berkurangdengan meningkatnya frekuensi.

Definisi pertama dapat dihasilkan oleh suatu algoritma yang mensimulasikan gerak Brown ataudengan mengintegrasikan white noise. "Brown" kebisingan tidak dinamai spektrum daya yang

menunjukkan bahwa warna coklat, melainkan nama adalah korupsi gerak Brown. "KebisinganMerah" menggambarkan bentuk dari spektrum kekuasaan, dengan merah muda yang antara

merah dan putih. Juga dikenal sebagai "random walk" atau "berjalan pemabuk itu" kebisingan.

Spektrum biru (+3 dB / oktaf)

Kerapatan kekuatan suara biru meningkat 3 dB per oktaf dengan meningkatnya frekuensi

(kerapatan proporsional dengan f) selama rentang frekuensi yang terbatas. Dalam grafikkomputer, "noise biru" istilah kadang-kadang digunakan lebih longgar karena setiap suara

dengan minimal komponen frekuensi rendah dan tidak ada lonjakan terkonsentrasi di energi.. Hal

ini dapat suara yang baik untukdithering . retina sel diatur dalam pola biru-suara seperti yangmenghasilkan resolusi visual yang baik.

Violet noise

Spektrum violet (+6 dB / oktaf)

Kepadatan daya Violet kebisingan meningkat 6 dB per oktaf dengan meningkatnya frekuensikerapatan proporsional dengan fselama rentang frekuensi yang terbatas. Hal ini juga dikenal

4/4

Spektrum abu-abu

Kebisingan abu-abu adalah white noise acak dikenakan kurva kenyaringan yang samapsychoacoustic (seperti terbalikkurva A-bobot ) selama rentang frekuensi tertentu, memberikan

pendengar persepsi bahwa itu adalah sama-sama keras pada semua frekuensi. Ini adalah berbeda

dengan kebisingan putih standar yang memiliki kekuatan yang sama atas skala linear frekuensi

tetapi tidak dianggap sebagai sama-sama keras karena bias pada manusiakontur kenyaringansama.

2. PENGUKURAN DI INDOR

Pengukuran di indoor menggunakan jarak 1.25 meter, karena pada jarak itu, sumber bunyi

merupakan sumber garis, karena kurang dari 5 kali diagonanalnya. Dimana diagonal speker yaitu

50 cm. Karena dianggap sumber garis, maka muka gelombangnya berupa silinder, sehingga arah

perambatannya lebih didominasi kedepan. Selain itu dengan jarak yang kecil/pendek makaintensitas bunyi akan semakin besar. Seperti yang diketahui intensitas berbanding kuadrat

dengan jarak..

I=

Dimana: I= intensitas

r= jarak antara speaker dan titik pengamat
