DVD革命的一大突破在于具有杜比数字环绕音响效果。相对于此前的双声道效果,其五声道环绕配置使得听觉效果更为逼真。然而因为要布置五个扬声器和一个低音炮,环绕立体声音响系统的室内安置也很让人挠头。此外,还要考虑声音对别人影响的问题。由于上述原因,几年前推出的杜比环绕无线耳机现在越来越受到人们的青睐,因为它能让你在不影响别人的情况下,身临其境一般欣赏电影、电视和音乐。 A major breakthrough in the DVD revolution is the Dolby Digital surround sound. Compared with the previous two-channel effect, its five-channel surround configuration makes the auditory effect more realistic. However, due to the layout of the five speakers and a subwoofer, the surround sound system is also very indifferent indoor placement. In addition, consider the issue of sound impact on others. For these reasons, Dolby Surround Wireless Headphones, introduced a few years ago, are now gaining in popularity as it enables you to enjoy movies, television and music on the go, without affecting others.
