Designation:E100714Standard Test Method forField Measurement of Tapping Machine Impact SoundTransmission Through Floor-Ceiling Assemblies andAssociated Support Structures1This standard is issued under the fixed designation E1007;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis test method is part of a set of standards for evaluating the sound insulating properties ofbuilding elements and sound isolation between spaces.It is designed to measure in the field the impactsound isolation between rooms or to estimate lower limits for impact sound transmission through afloor-ceiling partition element installed as an interior part of a building using a standard tappingmachine.Others in the set cover measurement of impact sound transmission through an isolatedfloor-ceiling assembly in a controlled laboratory environment(Test Method E492),the measurementof airborne sound transmission loss of an isolated partition element in a controlled laboratoryenvironment(Test Method E90),the measurement of airborne sound isolation and airborne soundtransmission loss associated with building elements in the field(Test Method E336),the measurementof sound transmission through building facades and facade elements in the field(Guide E966);and themeasurement of sound transmission through a common plenum between two rooms in a controlledlaboratory environment(Test Method E1414).1.Scope1.1 This test method covers the measurement of the trans-mission of impact sound generated by a standard tappingmachine through floor-ceiling assemblies and associated sup-porting structures in field situations.1.2 Measurements may be conducted on all types of floor-ceiling assemblies,including those with floating-floor or sus-pended ceiling elements,or both,and floor-ceiling assembliessurfaced with any type of floor-surfacing or floor-coveringmaterials.1.3 This test method defines several procedures and metricsto assess either the apparent performance of the nominallyseparating floor-ceiling or the isolation of a receiving roomfrom the sound produced by the operation of the tappingmachine.The receiving room may be the space directly belowthe tapping machine or,in some cases,any separated space thatreceives sound from the operation of the tapping machine.Thesource and receiving rooms as well as the floor-ceiling systemare identified and described in the test report.All measuredlevels and derivative single number ratings include the effect offlanking transmission.Efforts to suppress flanking are notpermitted.Available measures and their single number ratingsare the impact sound pressure levels(ISPL)and impact soundrating(ISR),the reverberation time normalized impact soundpressure levels(RTNISPL)and normalized impact soundrating(NISR),and the absorption normalized impact soundpressure levels(ANISPL)and apparent impact insulation class(AIIC).1.4 The ISPL and ISR may be measured and reportedbetween any two specific rooms or usage areas where thesource room area is large enough to accommodate the tappingmachine positions and the receiving room volume is suffi-ciently large to accommodate the microphone positions.For allother measures and ratings in this standard,restrictions such asminimum room volume or dimensions or maximum roomabsorption are imposed.Thus,conditions may exist that willnot allow RTNISPL(NISR)or ANISPL(AIIC)to be deter-mined.1.5 Where a separating floor-ceiling assembly is composedof parts that are constructed differently on the receiving room(ceiling)side,it is not possible to determine the ANISPL andAIIC of the individual elements or portions of the assembly.Inthis situation,the measurement will be of the compositestructure,not of an individual element.1This test method is under the jurisdiction ofASTM Committee E33 on Buildingand Environmental Acoustics and is the direct responsibility of SubcommitteeE33.03 on Sound Transmission.Current edition approved Sept.1,2014.Published November 2014.Originallyapproved 1984.Last previous edition approved in 2013 as E1007 13b.DOI:10.1520/E1007-14.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 1.6 Any single field measurement only represents the per-formance of the actual assembly tested and cannot be usedalone to accurately predict how an identical or similar assem-bly might perform.1.7 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.1.8 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.9 This standard does not purport to address all of thesafety concerns,if
