35、2832:2018ISO 16283-2:2018IntroductionISO 16283 (all parts) describes procedures for field measurements of sound insulation in buildings. Airborne, impact and faade sound insulation are described in ISO 162831, this document (ISO 162832) and ISO 162833, respectively.Field sound insulation measurement

36、s that were described previously in ISO 14041), ISO 14052), and ISO 14073)were a) primarily intended for measurements where the 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 (all parts) diffe

37、rs from ISO 1404, ISO 1405, and ISO 1407 in that:a) it applies to rooms in which the sound field may or may not approximate to a diffuse field;b) it clarifies how operators can measure the sound field using a hand-held microphone or sound level meter;c) it includes additional guidance that was previ

38、ously contained in ISO 140144).NOTE Survey test methods for field measurements of airborne and impact sound insulation are dealt with in ISO 10052.Two impact sources are described: the tapping machine and the rubber ball. These impact sources do not exactly replicate all possible types of real impac

39、ts on floors or stairs in buildings.The tapping machine can be used to assess a variety of light, hard impacts such as footsteps from walkers wearing hardheeled footwear or dropped objects. A single number quantity can be calculated using the rating procedures in ISO 7172. This single number quantit

40、y links the measured impact sound insulation using the tapping machine to subjective assessment of general impacts in dwellings that occur on floors or stairs in a building. The tapping machine is also well-suited to the prediction of impact sound insulation using ISO 12354-2. These two aspects faci

41、litate the specification of impact sound insulation in national building requirements using only measurements with the tapping machine as an impact source.The rubber ball can be used to assess heavy, soft impacts such as from walkers in bare feet or children jumping, as well as quantifying absolute

42、values that can be related to human disturbance in terms of a Fast timeweighted maximum sound pressure level.

43、EN ISO 162832:2018Acoustics - Field measurement of sound insulation in buildings and of building elements Part 2: Impact sound insulation1 ScopeThis document specifies procedures to determine the impact sound insulation using sound pressure measurements with an impact source operating on a floor or

44、stairs in a building. These procedures are intended for room volumes in the range from 10 m3to 250 m3in the frequency range from 50 Hz to 5 000 Hz. The test results can be used to quantify, assess and compare the impact sound insulation in unfurnished or furnished rooms where the sound field can app
