扬声器布局指南 | TheaterOwl

Calculating Speaker Placement is a fundamental and crucial step in home theater design. It is not just about measuring distance; it must be designed based on scientific evidence to maximize human visual perception limits and immersion. Incorrect settings can cause eye strain or fail to take advantage of resolution benefits. This tool complies with industry standards such as THX and SMPTE guides to provide the most precise data.

工作原理

This system utilizes complex trigonometry and optical formulas. Based on the input variables (screen size, resolution, viewing angle, etc.), it simultaneously calculates the minimum distance where pixels do not appear clustered and the maximum immersion distance that fills the entire field of view. All results are reflected in real-time, suggesting figures optimized for the user's environment.

应用场景

• When simulating the installation space before purchasing new Speaker Placement equipment
• When wanting to optimize the performance of an existing home theater system and achieve professional-level tuning
• When needing to find a compromise for the best audiovisual experience within space constraints

如何使用扬声器布局指南

选择环绕声配置，输入主聆听位置到前置扬声器的距离。指南基于ITU-R BS.775和杜比全景声指南计算推荐角度和距离。

前置左右扬声器应放置在中心±22–30°位置。5.1系统环绕扬声器放置在±90–110°，7.1后置扬声器放置在±135–150°。杜比全景声高度扬声器应在30–55°仰角。

尽量保持所有声道扬声器与聆听位置的距离相等。如果距离不同，使用AV功放的距离补偿设置（时间对齐）保持相位一致性。

常见问题

前置左右扬声器应该放在哪里？

前置L/R扬声器应放置在聆听位置±22-30°角，坐下时与耳朵齐平。与聆听位置形成等边三角形，稍微朝向聆听座位内倾。

5.1环绕扬声器的正确角度是多少？

5.1系统：前置L/R ±30°，中置0°，环绕L/R ±90-110°，低音炮任意位置（低音无方向性）。ITU-R BS.775推荐环绕扬声器±100-120°以获得最佳包围感。

杜比全景声高度扬声器应该安装多高？

杜比全景声高度扬声器（天花板或向上发射型）应位于聆听位置30-55°仰角处。嵌入式天花板扬声器在45°仰角效果最佳。
