34、 sound field could be considered to be diffuse, and (b) not explicit as to whether operators could be present in the rooms during the measurement. ISO 16283 differs from ISO 140-4, 5, and 7 in that (a) it applies to rooms in which the sound field may or may not approximate to a diffuse field, (b) it

35、 clarifies how operators can measure the sound field using a hand-held microphone or sound level meter and (c) it includes additional guidance that was previously contained in ISO 140-14.NOTE Survey test methods for field measurements of airborne and impact sound insulation are dealt with in ISO 100
