指引手册
适于分布式声音的扬声器布置
由于分布式声音为遍及某一区域的一般声音,因此应尽
可能均匀地布置各个扬声器,使该区域的各个位置声音
覆盖达到均衡。
将左右两侧的扬声器摆放在距主要收听区域距离尽量相
等的位置。
为避免产生音量过大的“热点”区域,应计划使用更多
的扬声器,并将各个扬声器的音量调低。
双声道立体声扬声器布置
将左右两侧的扬声器摆放在距主要收听区域距离相等(或尽
量相等)的位置。各扬声器距其最近的侧面墙的距离也应尽
量与该等距离接近。
等距
等距
理想情况下,左右两侧的扬声器之间的距离应比其距主要收
听区域的距离稍短。
家庭影院扬声器布置
左前、中置和右前扬声器应相对靠近视频显示器的
中心。
左前、中置和右前扬声器应尽量靠近视频显示器,而非
主要收听区域。例如,如果视频显示器距主要收听区
10 英尺(3 米),则扬声器应距主要收听区域 6 英尺
1.8 米)。
左前和右前扬声器应相对靠近视频显示器的两侧。
例如,当视频显示器为 50 英寸(1.2 米)时,左前和右
前扬声器相距一般不应超过 80 英寸(2 米)。
中置扬声器应与视频显示器的中心对齐。
环绕声声道扬声器应尽量远离主要收听区域,但距侧面
墙和背面墙至少应有 2 英尺(0.6 米)。
5.1 声道扬声器布置
5.1 声道系统中,左环绕声和右环绕声扬声器应直接
放置在主要收听区域的两侧,或放在其后方,最多呈
10 度角。
