5、of soundtransmission through a common plenum between two rooms(Test Method E1414).1.Scope1.1 The sound insulation properties of a door are measuredin a laboratory as the sound transmission loss in accordancewith Test Method E90.Using those data single number ratingsound transmission class(STC)is ass
6、igned.In the field,therooms on one or both sides of a partition containing a door areoften either too small or too large and absorptive to allow theapparent transmission loss(ATL)of the partition-door assem-bly to be measured.Even if that is not the case,the resultmeasured is the composite ATL of th
7、e partition including thedoor,and not that of the door itself.Test Method E336 actuallystates that it is impossible to measure the ATL of a portion ofa partition such as a door according to the procedures of thatstandard.This test method provides a method of evaluatingdoors in such cases using a nor
8、malized insertion loss with aresulting single number rating door transmission class,DTC.This method is intended primarily for hinged personnel doorswith latching mechanisms and is limited to door openings ofarea less than 6 m2.The flanking effects of surroundingstructure are reduced compared to E336
9、 but not completelyeliminated.In a laboratory environment,the DTC is close to orequal to the STC of the door,but in the field results less thanthe laboratory STC should be expected.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstand
