36、st methods for fans used in residential ventilation. These methods primarily concern: ventilation fans installed on a wall or in a window without any duct; ventilation fans installed in the downstream of a duct; ventilation fans installed in the upstream of a duct; ventilation fans installed in a du
37、ct; encased ventilation fans having several inlets. For acoustic performance testing one of the following methods is used: in-duct method; reverberant room method; enveloping surface method. 2 Normative references The following referenced documents are indispensable for the application of this docum
