也许不少对“家庭影院”有兴趣的人都会注意到“杜比”这个词。“杜比”是一家在音响界享有盛誉的美国实验室(公司)的名称,它的许多成果都被广泛应用于音响领域。例如“杜比降噪”系统,熟悉录音带的人都已深有印象。杜比在家庭影院方面的贡献之一就是其所谓的“杜比定向逻辑”系统。从发展的角度来看,在我们意识到要有更多声道的必要时,两声道已经在音响领域大行其道了。 Perhaps many people who are interested in “home theater” will notice the word “Dolby.” Dolby is the name of a U.S. laboratory (company) that has a strong reputation in the audio industry, and many of its many achievements are widely used in the audio industry.

One of Dolby’s contributions to home theater is what he calls “Dolby Pro Logic.” From a developmental point of view, two channels have become popular in the acoustics field as we realize the need for more channels.
