本出版物的中文版为译本。AMCA 300-14适用于所有类型和尺寸的风扇。它仅限于确定指定设置的空气声发射。未测量振动，也未确定空气声发射对振动影响的灵敏度。本标准中的测试设置要求确定了成功测试所需的实验室条件。在现场情况下，几乎不可能满足这些要求。本标准不适用于现场测量。在批准将其指定为美国国家标准的过程中，进行了一些小的编辑性修改。

The Chinese edition of this publication is a translation.AMCA 300-14 applies to fans of all types and sizes. It is limited to the determination of airborne sound emission for the specified setups. Vibration is not measured, nor is the sensitivity of airborne sound emission to vibration effects determined. The test setup requirements in this standard establish the laboratory conditions necessary for a successful test. Rarely will it be possible to meet these requirements in a field situation. This standard is not intended for field measurements. Minor editorial changes were made during the approval process for its designation as an American National Standard.
