立体声与环绕声
Since the old days, human beings have always been sensitive to sound. They used sounds to communicate and identify threats even before the languages were formed. After the languages were formed, sound was still used for a lot of things apart from talking. With the evolution of human beings, as well as, the technology, sound is still being used to serve various purposes. One of those well-known purposes is music or movies. Music has been there in the world for so long, but what makes it different now is that we get a record of music instead of the live performance that used to fill our minds ages back. It is this recorded sound that gives rise to the two varieties we are going to talk about today. The recorded sounds also differ where the initial recordings were in the form of gramophone discs and then the cassettes came to be. Much later in the 1990s came the CD, and with the usage of that, recorded music has been a widespread method of entertainment. It is with the invention of these Digital Media storage devices the concept of surround sound came to being. Let me talk about both of these individually before moving into a comparison.
What is Stereo Sound?
简而言之,如果您正在听电视,立体声,MP3播放器或盒式播放器,那么您会喜欢立体声音乐。用外行的话来说,立体声是您只有两个扬声器产生声音的地方。这两个扬声器也配有第三个子宣传炮,以便重现低音范围的声音。对于几乎所有制作的音乐和2000年之前制作的大多数电影来说,立体声声音都是一种工业规范。您将理解为什么立体声对音乐更好,而不是在我们解释包围的概念之后。出于同样的原因,环绕声系统的电影更好。因此,如今发行的大多数电影都是录制的。
什么是环绕声?
答案是相当简单的。环绕声系统s have more than 2 speakers, minimum 5 speakers to be precise. The sound systems we find as 5.7, 7.1 etc. are all surround sound systems. The home theater systems are also an example for surround sound systems. The enhancement in surround sound line is the fact that it reproduces directional sound. Further, they also give the perception of depth to sound. Let me give you an example for better understanding. Imagine you’re watching a surround sound recorded movie in a surround sound system that is been correctly setup, and you see a man emerging from one edge of the screen and walking off at the other edge. Now, in any normal or to be precise, Stereo condition, you would just hear the footsteps. But in this case, you would hear his footsteps coming towards you and then fading away to silence. In essence, surround sound means you’re surrounded by sounds and they make the movie come alive. Now you may understand why stereo is better for music since there is actually no need for directional sound in music. In fact, some people might mistake it for noise if there were to be directional music. On the other hand, the same reason makes it ideal to watch movie since everything around you comes to life and you can haven an immersed entertainment experience.
立体声声音与环绕声的简短比较 •立体声声音使用两个扬声器并产生非方向声音,而环绕声则使用至少5个扬声器并产生定向声音。 • Stereo Sound is good for music and Surround Sound is ideal for movies. |
结论
在决定是否获得环绕声系统还是立体声音响系统之前,需要决定使用声音系统的内容。但是在大多数情况下,这很可能是您要寻找的环绕系统,因为几乎所有时间,人们都有立体声套装并使用它来听音乐。因此,如果您试图找到一个声音系统与电视或DVD播放器连接,则可能要寻找环绕声系统。但是您需要警告说,环绕声系统的播放不是很好。他们使用的技术是在前两个扬声器上播放它们,但并非旨在播放立体音乐,音乐质量的差异是值得注意的。另一方面,反之亦然,因为立体声音响系统无法播放环绕声。值得一提的是,有些增强的环绕声系统也可以播放优质的立体声音乐,但是这些系统很复杂,因此非常昂贵。您需要担心的另一件事是,无论您的电视还是DVD播放器,还是您要连接到周围音响系统的任何播放器都支持解码环绕声。如果不是这种情况,那么您最好最终得到立体声音响系统。我几乎忘了提到最重要的事情之一。 Say you invested in a Surround Sound system, and since you have five speakers, you place them two on the right and two on the left and one in the middle. Well, if you did that, don’t scold us for giving you false hope for directional sound, as you are not going to get it that way. The placement of the speakers should be according to the manual, and most of the five speaker systems ask you to place two speakers at the front, two at the back and one in the middle. Therefore, make sure you place your speakers as instructed in the manual and get ready to enjoy a movie coming to life. That been said, I still haven’t heard a Surround Sound system that can beat Stereo Sound system to play music, and I’m sure that the gap will be bridged; but till then, Surround Sound will not be a multipurpose system.
