Kecepatan Bunyi

Bunyi merambat di udara dengan kecepatan 1.224 km/jam. Bunyi merambat lebih lambat jika suhu dan tekanan udara lebih rendah. Di udara tipis dan dingin pada ketinggian lebih dari 11 km, kecepatan bunyi 1.000 km/jam. Di air, kecepatannya 5.400 km/jam, jauh lebih cepat daripada di udara Rumus mencari cepat rambat bunyi adalah v=s:t Dengan s panjang Gelombang bunyi dan t waktu

Gelombang Bunyi

Gelombang bunyi terdiri dari molekul-molekul udara yang bergetar maju-mundur. Tiap saat, molekul-molekul itu berdesakan di beberapa tempat, sehingga menghasilkan wilayah tekanan tinggi, tapi di tempat lain merenggang, sehingga menghasilkan wilayah tekanan rendah. Gelombang bertekanan tinggi dan rendah secara bergantian bergerak di udara, menyebar dari sumber bunyi. Gelombang bunyi ini menghantarkan bunyi ke telinga manusia,Gelombang bunyi adalah gelombang longitudinal.

Gema

Gema terjadi jika bunyi dipantulkan oleh suatu permukaan, seperti tebing pegunungan, dan kembali kepada kita segera setelah bunyi asli dikeluarkan. Kejernihan ucapan dan musik dalam ruangan atau gedung konser tergantung pada cara bunyi bergaung di dalamnya. Bunyi atau suara adalah kompresi mekanikal atau gelombang longitudinal yang merambat melalui medium. Medium atau zat perantara ini dapat berupa zat cair, padat, gas. Jadi, gelombang bunyi dapat merambat misalnya di dalam air, batu bara, atau udara jadi, gema adalah gelombang pantul/ reaksi dari gelombang yang dipancarkan bunyi.

Kenyaringan dan Desibel

Bunyi kereta lebih nyaring daripada bunyi bisikan, sebab bunyi kereta menghasilkan getaran lebih besar di udara. Kenyaringan bunyi juga bergantung pada jarak kita ke sumber bunyi. Kenyaringan diukur dalam satuan desibel (dB). Bunyi pesawat jet yang lepas landas mencapai sekitar 120 dB. Sedang bunyi desiran daun sekitar 33 dB.
Kebanyakan suara adalah merupakan gabungan berbagai sinyal, tetapi suara murni secara teoritis dapat dijelaskan dengan kecepatan osilasi atau frekuensi yang diukur dalam Hertz (Hz) dan amplitudo atau kenyaringan bunyi dengan pengukuran dalam desibel.
Manusia mendengar bunyi saat gelombang bunyi, yaitu getaran di udara atau medium lain, sampai ke gendang telinga manusia. Batas frekuensi bunyi yang dapat didengar oleh telinga manusia kira-kira dari 20 Hz sampai 20 kHz pada amplitudo umum dengan berbagai variasi dalam kurva responsnya. Suara di atas 20 kHz disebut ultrasonik dan di bawah 20 Hz disebut infrasonik.

12-bit/108MHz video DAC
12-bit Video DAC is a superior Digital-to-Analogue-
Converter that preserves every detail of the authentic
picture quality. It shows subtle shades and smoother
graduation of colours, resulting in a more vibrant and
natural picture. The limitation of the usual 10bit DAC
become in particular apparent while using large screens
and projectors.
PAL & NTSC Progressive Scan
Progressive Scan doubles the vertical resolution of the
image resulting in a noticeably sharper picture. Instead of
sending fields with the odd lines to the screen first,
followed by the fields with the even lines, both fields are
written at one time. A flicker free high resolution image is
created giving you the best viewing experience.
Conical Dome Tweeters
Conical Dome Tweeters enhance SACD sound at the
highest frequencies by capturing every nuance and
inflection of sound by using an extremely light and stiff
membrane created of LEXAR, which allows the tweeters
to deliver a higher range of audio frequency. The special
cone shape of the reflector dish ensures a wider sound
distribution of the higher frequencies. This results in
stunningly clear and crisp highs and an overall more
balanced sound perception.
Multi-format Movies-DivX, MP4
Multi format playability allows you to play most disc
formats for maximum compatibility and viewing pleasure.
Music:SACDWindows Media™ Audio
Multi format playability allows you to play most disc
formats for maximum disc compatibility and listening

Speaker Setup for the Creative Sound Blaster Audigy 2 ZS Card

Your PC comes set up to produce sound through two
speakers and, depending on the speakers you have,
a subwoofer too. Some models may come set up for
5.1 channel mode.
If you have a 4, 6 (5.1 channel), 7 (6.1 channel), or 8
(7.1 channel) speaker system, follow these steps to get
proper sound from all speakers.
Connect all speakers to the correct audio connectors on
the subwoofer and the PC.
Refer to the manufacturer’s documentation included with
your speakers.
Speaker Setup in
Sound Blaster Audigy 2 ZS
1 Click Start on the taskbar.
2 Choose All Programs, Creative, Sound Blaster
Audigy 2 ZS, and then click Creative Speaker
Settings.
3 Select either 4/4.1 Speakers, 5.1 Speakers, 6.1
Speakers, or 7.1 Speakers from the
Speaker/Headphone Selection drop-down menu.
4 Check the Digital Output Only box when using
digital speakers (optional).
5 Close the Speaker Settings window.
Speaker Setup in
InterVideo WinDVD
You must complete the “Speaker Setup in Sound Blaster
Audigy 2 ZS” procedure above before proceeding.
1 Insert a DVD movie into the DVD-ROM drive. If the
DVD starts playing automatically, skip to step 4.
2 Click Start on the taskbar.
3 Choose All Programs, Video, InterVideo
WinDVD Player, and then click InterVideo
WinDVD 4.
4 Right-click in the video window, and then click Setup.
5 Select the Audio tab.
6 Under Audio Speaker Configuration, if you have
analog speakers, select either:
• 4 channel (Front L/R and Surround L/R)
