（1）關于Fan Noise，：
由于只有這一個是用于噪音的，所以我認為是適用于所有風機的噪音。
（2）domain部分幫助文檔的解釋是： The domain in which the blade is located
（3）Blade Selection: Set to Automatic for a single blade passage or Custom for a multiple blade passage. If this is set to Custom, you will need to specify the 2D region for the blade (Custom Blade) as well as the number of blades (Custom # Blades).
（4）# of Harmonics: The number of harmonics used in the calculation.
（5）Observer (r) and Observer (theta): The distance and location of the observer, relative to the blade.
（6）Theta Sectors: The number of sampling points (sectors) equally spaced over 360° at a given radius around the fan, used to calculate the noise values. A higher number leads to a more accurate solution, but takes more time to calculate.
（7）Directivity Harm. #: The harmonic level at which the sound pressure levels will be calculated.
（8）Loading Coeff.: A coefficient between 2 and 2.5.
