サブウーファー配置計算機 — Crawl法 & コーナーゲイン | TheaterOwl

Calculating Subwoofer 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.

仕組み

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.

活用 사례

• When simulating the installation space before purchasing new Subwoofer 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

サブウーファー配置計算機の使い方

部屋の寸法を入力すると、軸方向のルームモード周波数を計算し、サブウーファーの配置オプションを比較できます。

コーナー配置は境界ゲイン+6 dB を提供します。前面の壁は+3 dB。中央配置は最も均一な応答が得られます。

クロウルメソッド: サブウーファーを試聴位置の椅子に置き、低音テスト信号を再生して、部屋を歩き回り最適な位置を探します。
